What to do

AI-suggested

European organizations should prioritize the following specific mitigations: 1) Immediately identify and inventory all installations of Ashlar-Vellum Cobalt 12 SP1 within their environment. 3) Implement strict email and file filtering to block or quarantine suspicious CO files, especially from external or unknown senders. 4) Educate users on the risks of opening unsolicited or unexpected design files and the importance of verifying file sources. 5) Employ endpoint detection and response (EDR) solutions to monitor for anomalous behavior indicative of exploitation attempts, such as unexpected process launches or memory modifications related to Ashlar-Vellum Cobalt. 6) Use application whitelisting to restrict execution of unauthorized code and sandboxing to isolate the application where feasible. 7) Monitor threat intelligence feeds for any emerging exploits or indicators of compromise related to this vulnerability to enable rapid response.

Description

Ashlar-Vellum Cobalt CO File Parsing Type Confusion 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 CO files. The issue results from the lack of proper validation of user-supplied data, which can result in a type confusion condition. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-25981.
