Technical Analysis

CVE-2025-66835 describes a DLL hijacking vulnerability in TrueConf Client 8.5.2. An attacker with local access can exploit this by placing a malicious wfapi.dll, causing the application to load the attacker-controlled DLL and execute arbitrary code with the privileges of the user. The vulnerability is due to improper DLL search order or validation, categorized as CWE-427. The CVSS v3.1 score of 7.1 reflects high impact on confidentiality and integrity, with low attack complexity and requiring local privileges but no user interaction.

Potential Impact

Successful exploitation allows local attackers to execute arbitrary code within the user's security context, potentially leading to full compromise of the user's session and access to sensitive information. The vulnerability does not affect availability and requires local access with low complexity but no user interaction.

Mitigation Recommendations

No official patch or remediation guidance is currently available. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is released, restrict local access to trusted users and monitor for suspicious activity related to DLL loading in the application directory.
