Executive Summary

This vulnerability is a Denial of Service (DoS) issue in the AddAudioToVideoBlock component of the AutoGPT platform, affecting versions up to 0.6.62.

The problem occurs because AddAudioToVideoBlock downloads and stores video and audio files in a temporary directory but does not delete them after processing. Additionally, the StepThroughItemsBlock component can iterate the MediaDurationBlock multiple times without limiting the number of loops or the disk space consumed.

A malicious user can exploit this by repeatedly requesting audio additions to many videos, causing the disk space to fill up and resulting in a Denial of Service condition.

The vulnerability is worsened because processed videos with added audio are also stored in the working directory, further consuming disk space.

This issue is classified under uncontrolled resource consumption (CWE-400) and has a high severity with a CVSS score of 7.1.

Impact Analysis

This vulnerability can impact you by causing a Denial of Service (DoS) on the system running AutoGPT.

Because the system does not properly delete temporary video and audio files or limit disk space usage, a malicious user can fill up the disk space by repeatedly adding audio to videos.

Once the disk space is exhausted, the system may become unresponsive or fail to operate correctly, disrupting availability and potentially halting workflows that depend on AutoGPT.

Detection Guidance

This vulnerability can be detected by monitoring disk space usage on the system where AutoGPT is running, especially focusing on the temporary directories and the current working directory used by AddAudioToVideoBlock.

You can check for unusually large or growing files related to video and audio processing in these directories, which may indicate exploitation of the vulnerability.

Suggested commands to detect this condition include:

• Use disk usage commands to identify large files or directories: `du -sh /path/to/tempdir/*` and `du -sh /path/to/workingdir/*`
• Check overall disk space usage with: `df -h`
• List files sorted by size to find large video/audio files: `ls -lhS /path/to/tempdir` and `ls -lhS /path/to/workingdir`
• Monitor running processes that may be invoking AddAudioToVideoBlock or StepThroughItemsBlock excessively.

Mitigation Strategies

The immediate mitigation step is to upgrade AutoGPT to version 0.6.63 or later, where this vulnerability has been patched.

Until the upgrade can be applied, monitor and manage disk space carefully to prevent exhaustion caused by leftover temporary and output files.

Additionally, consider implementing manual cleanup scripts to delete temporary files created by AddAudioToVideoBlock after processing completes.

Limit or monitor the usage of StepThroughItemsBlock to prevent excessive looping that can lead to uncontrolled disk space consumption.

Compliance Impact

The vulnerability causes a Denial of Service (DoS) by uncontrolled disk space consumption, impacting system availability.

While the CVE description and resources do not explicitly mention compliance with standards such as GDPR or HIPAA, a DoS affecting availability could potentially impact compliance with regulations that require systems to maintain availability and reliability of services.

However, there is no direct information provided about data confidentiality, integrity, or privacy breaches related to this vulnerability, which are often critical for GDPR and HIPAA compliance.
