GHSA-826X-6XRJ-6VG9
Vulnerability from github – Published: 2025-03-11 21:30 – Updated: 2025-03-11 21:30
VLAI
Details
Ashlar-Vellum Cobalt VS File Parsing Use of Uninitialized Variable Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Ashlar-Vellum Cobalt. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the parsing of VS files. The issue results from the lack of proper initialization of memory prior to accessing it. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-25235.
