OpenText Brava! Desktop 16.6.3.84 DXF parsing memory corruption allows remote code execution via user opening malicious file.
Vulnerability
The vulnerability exists in OpenText Brava! Desktop version 16.6.3.84 during parsing of DXF files. The lack of proper validation of user-supplied data leads to memory corruption. User interaction is required (target must open a malicious file or visit a malicious page). [1]
Exploitation
An attacker can exploit this by crafting a malicious DXF file and persuading a user to open it with Brava! Desktop. No authentication is needed, and the attack is remote. [1]
Impact
Successful exploitation allows an attacker to execute arbitrary code in the context of the current process. This could lead to full compromise of confidentiality, integrity, and availability (CVSS 7.8). [1]
