CVE-2025-47133 is a high-severity out-of-bounds write vulnerability (CWE-787) affecting Adobe FrameMaker versions 2020.8, 2022.6, and earlier. This vulnerability arises when the software improperly handles memory boundaries during processing of certain input data, leading to a write operation outside the intended buffer limits. Such out-of-bounds writes can corrupt memory, potentially allowing an attacker to execute arbitrary code within the context of the current user. Exploitation requires user interaction, specifically that the victim opens a maliciously crafted FrameMaker file. The vulnerability does not require elevated privileges or prior authentication, but successful exploitation depends on tricking a user into opening a malicious file. The CVSS v3.1 base score is 7.8, reflecting high impact on confidentiality, integrity, and availability, with low attack complexity but requiring user interaction. No known exploits are currently reported in the wild, and no patches have been linked yet, indicating that organizations using affected versions remain at risk until updates are released. Adobe FrameMaker is a specialized document processing tool widely used in technical writing, particularly for complex documentation in engineering, aerospace, and manufacturing sectors.

For European organizations, this vulnerability poses a significant risk especially to industries relying on Adobe FrameMaker for technical documentation, such as aerospace, automotive, manufacturing, and engineering firms. Successful exploitation could lead to arbitrary code execution, enabling attackers to steal sensitive intellectual property, disrupt documentation workflows, or establish footholds for further network compromise. Given that FrameMaker documents are often shared internally and externally, the attack vector could be via spear-phishing or supply chain attacks targeting document exchange. The impact extends beyond confidentiality to integrity and availability of critical documentation, potentially affecting compliance with regulatory requirements for document control and traceability. The requirement for user interaction limits mass exploitation but targeted attacks against key personnel (e.g., technical writers, engineers) could be highly effective. The absence of patches increases the urgency for risk mitigation in affected environments.

European organizations should implement the following specific mitigations: 1) Immediately inventory and identify all systems running Adobe FrameMaker versions 2020.8, 2022.6, or earlier. 2) Until official patches are available, restrict usage of FrameMaker to trusted files only and implement strict email and file filtering to block or quarantine suspicious FrameMaker documents. 3) Educate users, especially technical writers and engineers, about the risks of opening unsolicited or unexpected FrameMaker files and encourage verification of file sources. 4) Employ endpoint detection and response (EDR) solutions to monitor for anomalous process behavior indicative of exploitation attempts. 5) Use application whitelisting to prevent unauthorized execution of code spawned by FrameMaker processes. 6) Segment networks to limit lateral movement if a compromise occurs. 7) Regularly back up critical documentation and verify backup integrity to enable recovery in case of disruption. 8) Monitor Adobe security advisories closely and apply patches promptly once released. 9) Consider deploying sandboxing or virtualized environments for opening untrusted FrameMaker files to contain potential exploits.
