CVE-2023-47043 is an out-of-bounds read vulnerability classified under CWE-125 affecting Adobe Media Encoder versions 24.0.2 and earlier, and 23.6 and earlier. The vulnerability arises during the parsing of crafted media files, where the software reads beyond the allocated memory buffer, potentially exposing sensitive data or enabling memory corruption. This memory corruption can be leveraged by attackers to execute arbitrary code within the context of the current user. Exploitation requires the victim to open a maliciously crafted file, making user interaction mandatory. The CVSS v3.1 base score is 7.8, reflecting high severity due to the combination of local attack vector, low attack complexity, no privileges required, but requiring user interaction, and high impact on confidentiality, integrity, and availability. Although no public exploits have been reported yet, the vulnerability's nature and impact make it a critical concern for environments where Adobe Media Encoder is used. The absence of patches at the time of reporting necessitates immediate risk mitigation through operational controls. Attackers could craft files that, when opened, trigger the out-of-bounds read leading to potential arbitrary code execution, data leakage, or system compromise. This vulnerability is particularly relevant for organizations involved in media production, broadcasting, and digital content creation, where Adobe Media Encoder is commonly deployed.

For European organizations, this vulnerability presents a significant risk especially for media companies, broadcasters, advertising agencies, and any enterprise relying on Adobe Media Encoder for content processing. Exploitation could lead to unauthorized code execution, data breaches, and disruption of media workflows. Confidentiality could be compromised through memory disclosure, while integrity and availability could be affected by arbitrary code execution leading to system instability or malware deployment. Given the requirement for user interaction, phishing or social engineering campaigns could be used to deliver malicious files. The impact is heightened in sectors with strict data protection regulations such as GDPR, where data leakage could result in regulatory penalties. Additionally, compromised media production environments could disrupt critical communications and content delivery, affecting business continuity and reputation.

Until Adobe releases a patch, European organizations should implement strict controls on file handling and user privileges. This includes disabling or restricting the use of Adobe Media Encoder to trusted users only, employing application whitelisting, and enforcing strict email and file scanning policies to detect and block malicious media files. User training to recognize suspicious files and avoid opening untrusted attachments is critical. Network segmentation can limit the spread of potential compromise. Monitoring for unusual application behavior or crashes related to Adobe Media Encoder can provide early detection. Organizations should also prepare to deploy patches promptly once available and consider using sandbox environments for processing untrusted media files. Employing endpoint detection and response (EDR) tools to identify exploitation attempts can further reduce risk.
