Overview
Adobe’s popular document processor software, Framemaker, has been identified as vulnerable to a critical Heap-based Buffer Overflow vulnerability, referenced as CVE-2025-47125. This vulnerability, if exploited, could grant malicious actors the ability to execute arbitrary code in the context of the current user. This flaw affects Adobe Framemaker versions 2020.8, 2022.6, and earlier. Given the widespread use of Adobe Framemaker in businesses for document processing, this vulnerability could have severe implications, potentially leading to system compromise or data leakage.

How the Exploit Works
The Heap-based Buffer Overflow vulnerability in Adobe Framemaker arises from the software’s failure to properly handle certain maliciously crafted files. When a user opens a malicious file, it triggers the overflow in the software memory heap. This overflow can be manipulated by an attacker to execute arbitrary code in the user’s context. The exploit is particularly insidious because it requires no elevated privileges and is initiated through a seemingly innocuous user action: opening a file.
Conceptual Example Code
To visualize this, consider an attacker creating a malicious Framemaker file with a payload designed to trigger the overflow. The file might look something like this:
FRAMEMAKER_OPEN
"malicious_data": "A"*8000 + "B"*8000 + "C"*4000 + "shellcode"
FRAMEMAKER_CLOSEThis is a simplified representation, but it conveys the idea. The “A”*8000, “B”*8000, and “C”*4000 are filler data meant to overflow the heap buffer. The “shellcode” would be the malicious code that the attacker wants to execute.
Please note: This is a conceptual representation only. Malicious activity is unlawful and strictly against the ethical guidelines of cybersecurity practices.
