Adobe After Effects version 18.4 (and earlier) is affected by a memory corruption vulnerability due to insecure handling of a malicious .m4a file, potentially resulting in arbitrary code execution in the context of the current user. User interaction is required in that the victim must open a specially crafted file to exploit this vulnerability. This high-severity issue has a CVSS score of 7.8, indicating significant risk.
Risk to organizations includes potential unauthorized access and control over affected systems. Attackers may leverage this vulnerability to execute malicious code, making it imperative for users to address it promptly. Given the requirement for user interaction, the attack vector is primarily local, but the consequences could be severe.
Organizations should prioritize patching immediately. The vulnerability was published on November 18, 2021, and has been modified since. Users must ensure they are operating on the most recent version of Adobe After Effects to mitigate this risk.
Monitoring for signs of exploitation and ensuring proper security measures are in place will help organizations defend against potential attacks leveraging this vulnerability.
Vulnerability Details
The vulnerability allows for potential arbitrary code execution due to improper handling of malicious audio files. The CVSS score of 7.8 indicates a high severity level, which reflects the serious implications for confidentiality, integrity, and availability.
Adobe has classified this as a memory corruption issue (CWE-119) alongside another weakness (CWE-788). The affected product is Adobe After Effects, specifically versions prior to 18.4.1. The vulnerability requires user interaction, heightening the risk during file opening operations.
Technical Analysis
The root cause of the vulnerability lies in the memory management of the application when processing .m4a files. This leads to a situation where an attacker can craft a malicious audio file, and when the victim opens this file, arbitrary code execution can occur. The attack vector is local, and the complexity is low, requiring no special privileges. User interaction is necessary, as victims must open the crafted file.
The impact on confidentiality, integrity, and availability is rated as high. If successfully exploited, attackers could potentially take full control of the affected system, leading to severe consequences.
Risk & Impact Analysis
The real-world deployment risk is considerable, especially in environments where Adobe After Effects is used for creative production. The potential blast radius is significant, as exploitation could lead to unauthorized access to sensitive information and the ability to execute arbitrary code within the context of the user.
Given the CVSS score of 7.8 and the fact that it is not listed in the KEV catalog, organizations must urgently assess their exposure and implement the necessary patches. The urgency for remediation is high due to the potential for exploitation.

Affected Versions
The affected versions include Adobe After Effects version 18.4 and earlier, specifically up to version 18.4.1. Organizations are encouraged to check their installations and ensure they are updated to the latest version to mitigate this vulnerability.
Mitigation & Remediation
Adobe has released patches to address this vulnerability. Organizations should upgrade to the latest version of Adobe After Effects to remediate this vulnerability. In cases where the patch cannot be applied immediately, consider implementing configuration hardening measures to limit exposure.
Monitoring systems for unusual behavior and ensuring that users are trained to recognize malicious file types will also be beneficial. For further insights on vulnerability management, organizations may refer to vulnerability management programs to strengthen their overall security posture.
Detection Guidance
To detect potential exploitation of this vulnerability, organizations should monitor logs for indicators such as unexpected application crashes, unusual file access patterns, and any unauthorized changes to application configurations.
Behavioral anomalies in user interactions with .m4a files should also be investigated, as these may indicate attempts to exploit this vulnerability.
AppSecure Threat Intelligence Insight
