Soar 101: Security, Orchestration, Automation, and Response

Security, Orchestration, Automation, and Response (SOAR) is still a foreign concept to some but has rapidly evolved into a necessity for high-performing SOCs. SOCs without a SOAR — or without meaningful automation — will struggle with manual repetition, duplicate alerts, and slow response times as they scale. With SOAR, many of these problems can be addressed or reduced.

While SOAR isn’t a “silver bullet” by any means, the operational impacts are real because of the power it gives a SOC to optimize workflows, centralize security alert management, and minimize threat response time (or mean time to resolution). According to the Ponemon Institute, organizations can receive on average upwards of 17,000 malware alerts per week. The BHIS Active SOC reduced overall ticket volume by roughly 60% through intelligent alert grouping — consolidating related signals into single cases instead of working them as individual alerts.

How SOAR Works

To understand how this is possible, we need to discuss what SOAR is and how it works. A SOAR is a platform specialized primarily around security use cases. This platform serves as a centralized hub for data enrichment, integrations, and response actions, all of which take place in the context of “playbooks.” Think of a playbook as a flowchart, where each step performs a specific operation.

At the top of the flowchart, data (let’s say an EDR alert) initially enters the playbook. As it continues, decision points control the directional flow, API requests gather additional data or perform actions, and finally, there is some sort of output. So, a SOAR is really a technology—a curated set of tools and processes that work together to automate what can be wisely automated so as to serve as a happy medium between total manual management and total automation to maximize a SOC team’s ability to respond quickly and appropriately despite the problems and time constraints that the team encounters due to sheer volume.

Real-World Application

Consider a real-world example: Suppose that a device triggers a low-confidence EDR alert. Since it’s low-confidence, the EDR doesn’t take any action and sends it to the SOAR. The SOAR makes an API call out to VirusTotal (a service for detecting malware) with the indicators of compromise (IOCs) of the alert. If the IOCs return as malicious, the SOAR reaches back to the EDR, which in turn, isolates the host.

Now let’s say that this EDR alert fired 100 times, each on a different signature, all on the same host. Let’s also say that network detections for Command and Control also started firing related to that user. With a SOAR, all of those disparate signals could be condensed into one singular Case, rather than a number of individual alerts. Using logic within your SOAR playbooks, you could group all these events together based on numerous field values, going a layer deeper than you normally could with a SIEM, which usually just allows for the suppression of duplicates.

Challenges of Implementing SOAR

Now that you understand the potential power of a SOAR, you might be asking, “Hayden, why isn’t everyone using a SOAR then?” There are a few good reasons for that:

  1. A high price tag: While some offerings are maybe tens of thousands a year, some of the larger enterprise offerings could run you hundreds of thousands a year just to purchase the product.
  2. Required expertise: A SOAR is a very powerful, but very delicate, tool. Used correctly, it could do the work of several FTEs for your team; used incorrectly, at best it may not work as you want, and at worst it could cause runaway scenarios of automated containment or remediation. Having qualified SOAR engineers on your team is critical to extract the true value of the technology.
  3. Implementation effort: Even the most expensive SOAR won’t solve all your problems immediately. Like any technology, it will require maintenance and updates, but with a SOAR, you also have to build many of the functions that you need or at least cater them to your use cases.

The Bottom Line

It may sound like I’m trying to convince you that a SOAR isn’t worth the effort, but that couldn’t be further from the truth. On the contrary, SOAR is becoming an expectation for any high-performing SOC, rather than a nice-to-have. As volume and complexity of alerts increase, a SOAR becomes essential to respond quickly and adequately to these alerts.

How an image could compromise your Mac: understanding an ExifTool vulnerability (CVE-2026-3102)

exiftools featured

Introduction

ExifTool is a widely adopted utility for reading and writing metadata in image, PDF, audio, and video files. It is available both as a standalone command-line application and as a library that can be embedded in other software. In this article, we break down CVE-2026-3102, an ExifTool vulnerability discovered by Kaspersky’s Global Research and Analysis Team (GReAT) in February 2026 and patched by the developers within the same month. Affecting macOS systems with ExifTool version 13.49 and earlier, this flaw could let an attacker run arbitrary commands by hiding instructions inside an image file’s metadata.

This investigation originated from revisiting an n-day vulnerability I first examined years ago: CVE-2021-22204. That flaw exploited weak regex-based sanitization before feeding user input into an eval sink. By auditing adjacent input validation routines across ExifTool codebase for similar oversights, I discovered CVE-2026-3102. Successful exploitation of CVE-2026-3102 enables an attacker to execute arbitrary shell commands with the privileges of the user invoking ExifTool, potentially leading to full system compromise.

Technical details

Disclaimer

Exploiting CVE-2026-3102 requires the -n (also known as -printConv) flag and outputs machine-readable data without additional processing.

Tracing the vulnerable sink

Taint analysis (aka tainted data analysis) allows for the detection of “dirty” data that reaches dangerous locations without validation. In this context, a “sink” is a point or function in a program where data or a parameter marked as “tainted” or originating from an untrusted source (e.g., user input) can affect the program’s behavior. In ExifTool, these functions are eval and system, both of which are capable of executing system commands. While CVE-2021-22204 exploited an eval function as a sink, this vulnerability (CVE-2026-3102) targets the system function. Knowing the vulnerable sink, we needed to trace how user-controlled data reaches it. Below, we break down the details.

Finding an unsanitized date value

The screenshot above shows where the system() sink resides within the SetMacOSTags function. Tracing backward from system(), we identified the $cmd variable as the source of the executed command. This variable is assembled from three inputs: $file (properly sanitized), $setTags (processed iteratively), and $val (user-controlled and, crucially, left unsanitized in the vulnerable branch).

In ExifTool, a tag is a named metadata field. When parsing an image, the utility extracts date and time values from standard EXIF records or macOS filesystem attributes. To handle file creation dates on macOS, ExifTool relies on the Spotlight system attribute MDItemFSCreationDate. Within the program code, this attribute maps to the internal alias $FileCreateDate. These two identifiers govern how the file creation date is stored and applied.

This creates a critical link to the vulnerability: when parsing an image, ExifTool iterates through the discovered tags. The current tag’s name is assigned to the $tag variable, while its text content (e.g., a date string) is assigned to $val. The vulnerable code path is triggered only when $tag matches MDItemFSCreationDate or $FileCreateDate. At this point, the tag’s content flows into $val and is passed to the SetMacOSTags function. As shown in the screenshot below, the filename parameter is properly escaped, but the date value ($val) is not. Because the date is extracted directly from file metadata, an attacker can inject quotes into this field. This breaks the command structure and allows the payload to execute via the system() sink.

The following screenshots show some of the tags that can be modified. With the vulnerable parameter identified, the next challenge was delivery: how to place our payload into FileCreateDate without triggering early validation? We found the answer in the official documentation.


Planning the payload delivery

Let’s refer to the documentation to understand how ExifTool handles tag operations and identify a legitimate feature that can be repurposed for exploitation. Specifically, we need to find a way to deliver our payload into the vulnerable FileCreateDate parameter. When looking for macOS-related tags as well as FileCreateDate, we can find the following information:

  • To write or delete metadata, tag values are assigned using –TAG=[VALUE], and/or the -geotag, -csv= or -json=
  • To copy or move metadata, the -tagsFromFile feature is used.

(You can find the useful info on tag operations above and how it relates under the hood in ExifTool in the dedicated section of the documentation and on the ExifTool description page.)

To trigger the vulnerability, we need to copy a string (date format: MM/DD/YYYY) using the -tagsFromFile feature, as this operation invokes the SetMacOSTags function where the unsanitized $val parameter reaches the system() sink.

Why copy instead of writing directly? Because the vulnerable code path (SetMacOSTags) is only triggered when metadata is copied into FileCreateDate — not when it is written directly. By using -tagsFromFile, we can prepare a “source” tag (e.g., DateTimeOriginal) that accepts arbitrary values and copy that value into FileCreateDate, thereby invoking the vulnerable function with our controlled input.

Furthermore, we want to introduce single quotes (since they are not being escaped in $val). For starters, we can look for date-time tag and copy via -tagsFromFile by searching the EXIF tag table. Direct assignment to FileCreateDate is heavily validated, so we looked for a source tag that accepts raw values and can be copied into the target field. The following snippet shows the beginning of said table.

When doing the analysis, I made use of DateTimeOriginal though I believe you can also use CreateDate which is 0x9004 (see the following screenshot). Initial attempts to inject malformed dates failed: ExifTool’s built-in filter rejected the input. To bypass this, we examined how the tool handles raw metadata.

Bypassing the filter

To confirm that the PrintConvInv filter rejects invalid dates when written directly, I ran the following command, where evil_benign.jpg is a normal JPG with an invalid date time format. We are greeted with the error message: Invalid date/time. This requires the time as well. The next screenshot confirms that direct exploitation fails: ExifTool’s date validation detects the malformed input and rejects the change, activating the internal PrintConvInv filter.

That said, it is possible to ignore the formatting and use the -n flag which accepts raw values instead of human-readable value.  The -n flag skips the PrintConvInv conversion step, which is exactly where input sanitization occurs. This confirmed we could park unsanitized data in a source tag. The final step was to trigger the vulnerable code path by copying that data into FileCreateDate. This means we should now be able to modify the DateTimeOriginal tag with the invalid date time format with an -n flag. Examining the EXIF metadata tag, we can confirm that we can store a raw value without a proper human readable format that ExifTool accepts:

Triggering the exploit

To inject commands, we have to revisit the single quote injection into this datetime related tag.

The following screenshot shows that we have successfully set the datetime metadata with the single quote. With the payload safely stored in a source tag, the next step was to copy it into FileCreateDate, triggering the vulnerable system() call.

The next step now is to copy the datetime tag to a file which invokes SetMacOSTags. According to the documentation, this is how we can copy the data from the SRC tag to the FileCreateDate tag as seen in the SetMacOSTags with the -tagsFromFile feature.

exiftool [_OPTIONS_] -tagsFromFile _SRCFILE_ [-[_DSTTAG_<]_SRCTAG_...] _FILE_...

Therefore, we can craft our final command:

cp evil_benign.jpg pwn.jpg;
../../exiftool -n -tagsFromFile evil_benign.jpg "-FileCreateDate<DateTimeOriginal" pwn.jpg

Here, we confirm that the payload has been executed! Note that when copying tags in MacOS (Darwin), the /usr/bin/setfile command is used. To view the full $cmd value before the injection, I have added the debugging statement to displaying the actual command that is executed within the system function.

Upon injection, we can see that our command gets executed via command substitution. The single quotes that we added helped to make the entire command syntactically valid. The following shows a more detailed labelling and their roles in making this command line injection successful:

Such an image can appear completely benign and easily find its way into a newsroom or any organization that processes photos on macOS using ExifTool. Once processed, an attacker could silently deploy a Trojan for covert data exfiltration, drop additional malware, or use the compromised machine as a foothold to expand the attack within the victim’s network.

Patch analysis

After verifying successful exploitation, we examined how the maintainer addressed the flaw in version 13.50. In the vulnerable version of ExifTool, commands were sanitized before being concatenated together. This means that it is possible to concatenate single quotes which led to the exploitation. However, by abstracting the system call into a dedicated wrapper and requiring a list of arguments instead of concatenated string, the fix removes the need for any manual escaping altogether.

1. Replacing string form to argument list form:

#### BEFORE
$cmd = "/usr/bin/setfile -d '${val}' '${f}'";
system $cmd;
  
#### AFTER
system('/usr/bin/setfile', '-d', $val, $file);

2. Create new System() wrapper. In version 13.49, the output is piped to /dev/null . To maintain that logic, the wrapper would temporarily redirect STDOUT/STDERR to /dev/null and restore them after the call.

# Call system command, redirecting all I/O to /dev/null
# Inputs: system arguments
# Returns: system return code
sub System
{
    open(my $oldout, ">&STDOUT");
    open(my $olderr, ">&STDERR");
    open(STDOUT, '>', '/dev/null');
    open(STDERR, '>', '/dev/null');
    my $result = system(@_);
    open(STDOUT, ">&", $oldout);
    open(STDERR, ">&", $olderr);
    return $result;
}

How to protect against ExifTool vulnerability

It’s critical to ensure that all photo processing workflows are using the updated version. You should verify that all asset management platforms, photo organization apps, and any bulk image processing scripts running on Macs are calling ExifTool version 13.50 or later, and don’t contain an embedded older copy of the ExifTool library.

ExifTool, like any software, may contain additional vulnerabilities of this class. To harden defenses, I recommend using Kaspersky Open Source Software Threats Data Feed for continuous monitoring of open-source components in your software supply chain, and Kaspersky for macOS as comprehensive endpoint protection. Additionally, isolate processing of untrusted files on dedicated machines or virtual environments with strictly limited network and storage access. If you work with freelancers, contractors, or allow BYOD, enforce a policy that only devices with an active macOS security solution can access your corporate network.

Conclusions

CVE-2026-3102 highlights the risks of inconsistent input sanitization in tools that bridge high-level metadata parsing with platform-specific utilities. While exploitation requires explicit flag usage (-n) and is restricted to macOS, the vulnerability underscores the danger of manual escaping routines in evolving codebases. The transition to list-form system execution provides a robust, architecture-level fix that eliminates shell interpretation risks entirely. This case reinforces a core security principle: replacing fragile string concatenation with secure, list-based API calls remains the most reliable mitigation against command injection.
