CVE-2021-28596: Out-of-bounds Write (CWE-787) in Adobe FrameMaker
Adobe Framemaker version 2020.0.1 (and earlier) and 2019.0.8 (and earlier) are affected by an Out-of-bounds Write vulnerability when parsing a specially crafted file. An unauthenticated attacker could leverage this vulnerability to achieve arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
AI Analysis
Technical Summary
CVE-2021-28596 is an out-of-bounds write vulnerability (CWE-787) found in Adobe FrameMaker versions 2020.0.1 and earlier, as well as 2019.0.8 and earlier. This vulnerability occurs during the parsing of specially crafted FrameMaker files, where improper bounds checking allows an attacker to write data outside the intended buffer boundaries. Such memory corruption can lead to arbitrary code execution within the context of the current user. Exploitation requires user interaction, specifically that the victim opens a maliciously crafted FrameMaker document. The attacker does not need to be authenticated to exploit this vulnerability, but successful exploitation depends on convincing the user to open the malicious file. There are no known exploits in the wild reported to date, and no official patches or updates are linked in the provided information. The vulnerability affects widely used versions of FrameMaker, a desktop publishing and document processor application primarily used for technical documentation and publishing workflows.
Potential Impact
For European organizations, the impact of this vulnerability could be significant in environments where Adobe FrameMaker is used, particularly in sectors reliant on technical documentation such as aerospace, automotive, manufacturing, and engineering firms. Successful exploitation could allow attackers to execute arbitrary code, potentially leading to data theft, installation of malware, or lateral movement within the network. Since the code execution occurs with the privileges of the current user, the impact depends on the user's access rights; however, many users may have access to sensitive documents or network resources. The requirement for user interaction limits the attack vector to targeted phishing or social engineering campaigns distributing malicious FrameMaker files. Given the lack of known exploits in the wild, the immediate risk may be moderate, but the vulnerability remains a potential vector for targeted attacks against organizations using FrameMaker in Europe.
Mitigation Recommendations
1. Immediately update Adobe FrameMaker to the latest available version beyond 2020.0.1 or 2019.0.8 once patches are released by Adobe. 2. Implement strict email and file attachment filtering to detect and block suspicious FrameMaker files, especially from unknown or untrusted sources. 3. Educate users on the risks of opening unsolicited or unexpected FrameMaker documents, emphasizing verification of file sources before opening. 4. Employ application whitelisting and sandboxing techniques to restrict FrameMaker’s ability to execute arbitrary code or access sensitive system resources. 5. Monitor endpoint behavior for unusual activity following the opening of FrameMaker files, including unexpected process spawning or network connections. 6. Use endpoint detection and response (EDR) tools to detect exploitation attempts or anomalous memory corruption behaviors. 7. Where possible, limit user privileges to reduce the impact of potential code execution. 8. Maintain regular backups of critical documentation and system states to enable recovery in case of compromise.
