CVE-2021-44699 is an out-of-bounds read vulnerability (CWE-125) affecting Adobe Audition versions 14.4 and earlier, as well as version 22.0 and earlier. This vulnerability arises when Adobe Audition processes specially crafted MP4 files, leading to an out-of-bounds read condition that can disclose sensitive memory contents. The flaw can be exploited by an attacker who convinces a user to open a malicious MP4 file within the vulnerable Adobe Audition application. The out-of-bounds read may allow attackers to bypass security mitigations such as Address Space Layout Randomization (ASLR), which is designed to prevent exploitation of memory corruption vulnerabilities by randomizing memory addresses. Although the vulnerability itself does not directly allow code execution or privilege escalation, the information disclosure can be leveraged to facilitate further attacks. Exploitation requires user interaction, specifically opening a malicious file, and there are no known public exploits in the wild as of the published date. The vulnerability affects multiple versions of Adobe Audition, a professional audio editing software widely used in media production environments. No official patches or updates are linked in the provided information, indicating that organizations should verify with Adobe for available fixes or workarounds. The vulnerability is classified as medium severity, reflecting the moderate impact and exploitation complexity.

For European organizations, the primary impact of CVE-2021-44699 lies in the potential leakage of sensitive memory information, which could include cryptographic keys, user credentials, or other confidential data residing in memory during audio processing. Media production companies, broadcasters, advertising agencies, and any enterprises relying on Adobe Audition for audio editing are at risk. The information disclosure could be a stepping stone for attackers to bypass ASLR and mount more sophisticated attacks, potentially leading to further compromise of systems. While the vulnerability does not directly cause system crashes or remote code execution, the breach of confidentiality can undermine trust and lead to intellectual property theft or exposure of sensitive project data. Given the requirement for user interaction, social engineering or phishing campaigns targeting employees who handle audio files could be used to deliver malicious MP4 files. The impact is thus more pronounced in organizations with less stringent security awareness or those that frequently exchange multimedia files. The vulnerability may also affect organizations involved in critical infrastructure sectors if Adobe Audition is used in operational environments, potentially exposing sensitive operational data.

Verify with Adobe for the availability of official patches or updates addressing CVE-2021-44699 and apply them promptly. Implement strict email and file filtering to detect and block malicious MP4 files, especially those received from untrusted or unknown sources. Educate users, particularly those in media and production roles, about the risks of opening unsolicited or suspicious multimedia files and encourage verification before opening. Use application whitelisting and sandboxing techniques to limit the execution context of Adobe Audition, reducing the impact of potential exploitation. Monitor system and application logs for unusual behavior or crashes related to Adobe Audition that could indicate exploitation attempts. Restrict the use of Adobe Audition to trusted environments and consider isolating it from critical network segments to limit lateral movement in case of compromise. Employ memory protection technologies and keep operating systems and security software up to date to complement mitigation of memory disclosure vulnerabilities.
