CVE-2025-30299 is a heap-based buffer overflow vulnerability identified in Adobe Framemaker versions 2020.8, 2022.6, and earlier. The vulnerability arises from improper handling of memory buffers when processing Framemaker files, leading to a situation where an attacker can overflow a heap buffer. This overflow can corrupt memory and enable arbitrary code execution within the context of the current user. Exploitation requires the victim to open a maliciously crafted Framemaker file, meaning user interaction is necessary. The vulnerability does not require any prior authentication, increasing its risk profile. The CVSS v3.1 score of 7.8 indicates a high severity, with the vector showing local attack vector (AV:L), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Although no public exploits are known at this time, the potential for arbitrary code execution makes this a critical concern for users of affected Framemaker versions. The lack of available patches at the time of disclosure necessitates immediate attention to mitigation strategies.

The exploitation of this vulnerability can lead to complete compromise of the affected system under the privileges of the current user. This includes unauthorized disclosure of sensitive information, modification or deletion of data, and disruption of system availability. For organizations relying on Adobe Framemaker for technical documentation, publishing, or content creation, a successful attack could result in intellectual property theft, operational disruption, and potential lateral movement within the network if the compromised user has elevated privileges. Since exploitation requires user interaction, phishing or social engineering campaigns could be used to deliver malicious files, increasing the risk in environments where users frequently exchange Framemaker documents. The absence of known exploits currently reduces immediate risk but does not eliminate the threat, especially once exploit code becomes publicly available.

Organizations should implement the following specific mitigation measures: 1) Monitor Adobe’s official channels closely for patches addressing CVE-2025-30299 and apply updates immediately upon release. 2) Restrict the use of Adobe Framemaker to trusted users and environments, limiting exposure to untrusted files. 3) Implement strict email and file scanning policies to detect and block malicious Framemaker files before they reach end users. 4) Educate users on the risks of opening unsolicited or unexpected Framemaker documents, emphasizing caution with files from unknown sources. 5) Employ application whitelisting and sandboxing techniques to limit the impact of potential exploitation. 6) Use endpoint detection and response (EDR) tools to identify anomalous behavior indicative of exploitation attempts. 7) Regularly back up critical documentation and data to enable recovery in case of compromise. These targeted actions go beyond generic advice by focusing on controlling file sources, user behavior, and rapid patch deployment.
