CVE-2025-54282 is a heap-based buffer overflow vulnerability identified in Adobe Framemaker versions 2020.9, 2022.7, and earlier. The vulnerability arises due to improper handling of input data when processing Framemaker files, leading to a buffer overflow condition on the heap. This memory corruption can be exploited by an attacker to execute arbitrary code within the context of the current user. The attack vector requires that the victim open a maliciously crafted Framemaker file, thus necessitating user interaction but no prior authentication or elevated privileges. The vulnerability is classified under CWE-122 (Heap-based Buffer Overflow), which typically allows attackers to overwrite memory, potentially hijacking control flow or corrupting data. The CVSS v3.1 score of 7.8 reflects a high severity with the vector string AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, indicating local attack vector, low attack complexity, no privileges required, user interaction required, unchanged scope, and high impact on confidentiality, integrity, and availability. No patches or public exploits have been reported at the time of publication, but the risk remains significant due to the potential for arbitrary code execution. Organizations using Adobe Framemaker should monitor for vendor patches and advisories.

For European organizations, the impact of this vulnerability can be substantial, especially in sectors relying heavily on Adobe Framemaker for technical documentation, publishing, or content creation. Successful exploitation could lead to unauthorized disclosure of sensitive information, modification or destruction of critical documents, and potential lateral movement within networks if attackers escalate privileges post-exploitation. The requirement for user interaction means phishing or social engineering campaigns could be used to deliver malicious files, increasing risk in environments with less stringent email or file handling policies. Confidentiality, integrity, and availability of organizational data are all at risk, potentially affecting compliance with GDPR and other data protection regulations. The disruption caused by arbitrary code execution could also impact business continuity and operational workflows.

European organizations should implement the following specific mitigations: 1) Immediately inventory and identify all systems running affected versions of Adobe Framemaker (2020.9, 2022.7, and earlier). 2) Monitor Adobe’s official channels for patches or security updates and apply them promptly once released. 3) Enforce strict file handling policies, including disabling automatic opening of Framemaker files from untrusted sources and scanning all incoming files with advanced malware detection tools. 4) Educate users on the risks of opening unsolicited or suspicious Framemaker documents, emphasizing the need for caution with email attachments and downloads. 5) Employ application whitelisting and sandboxing techniques to limit the execution context of Framemaker and contain potential exploits. 6) Utilize endpoint detection and response (EDR) solutions to detect anomalous behaviors indicative of exploitation attempts. 7) Regularly back up critical documentation and ensure backups are isolated from the main network to prevent ransomware or data corruption impacts.
