CVE-2025-47123: Adobe FrameMaker Heap Overflow Allows Arbitrary Code Execution
Adobe FrameMaker is susceptible to a heap-based buffer overflow vulnerability. If exploited, this could allow an attacker to execute arbitrary code on a victim's machine. User interaction is required, meaning the victim must open a specially crafted malicious file.
Vulnerability Details
- CVE ID: CVE-2025-47123
- Description: Adobe Framemaker versions 2020.8, 2022.6 and earlier are affected by a Heap-based Buffer Overflow vulnerability that could result in 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.
- CVSS Score: 7.8 HIGH
- CVSS Vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
- CVSS Vector Explanation: This means the vulnerability is locally exploitable with low complexity, no privileges are needed, but user interaction (opening a malicious file) is required. A successful exploit has high impact on confidentiality, integrity, and availability.
- Exploit Requirements: An attacker needs to craft a malicious FrameMaker file and convince a user to open it.
- Affected Products: Adobe FrameMaker versions 2020.8, 2022.6 and earlier.
- CWE: CWE-122 - Heap-based Buffer Overflow. This means the program writes data past the end of an allocated buffer on the heap, potentially overwriting other important data or injecting malicious code.

Exploitability & Real-World Risk
While the exploit requires user interaction, malicious actors could easily distribute crafted FrameMaker files via email, social engineering, or compromised websites. Given the widespread use of FrameMaker in document creation and publishing, successful exploitation poses a significant risk to organizations and individuals.
Recommendations
- Apply the latest Adobe FrameMaker updates. Adobe has released patches to address this vulnerability.
- Exercise caution when opening FrameMaker files from untrusted sources. Verify the sender's identity and the file's legitimacy before opening.
- Implement security awareness training. Educate users about the risks of opening suspicious files.
Technical Insight
The heap-based buffer overflow likely occurs when FrameMaker processes a malformed or oversized data structure within a FrameMaker file. This allows an attacker to overwrite memory regions on the heap, potentially redirecting program execution to malicious code injected into the file.
