DescriptionNVD

KeePassXC OpenSSL Configuration Uncontrolled Search Path Element Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of KeePassXC. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.

The specific flaw exists within the configuration of OpenSSL. The product loads configuration from an unsecured location. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of KeePassXC when run by a target user on the system. Was ZDI-CAN-29156.

AnalysisAI

Local privilege escalation in KeePassXC password manager allows authenticated attackers with low privileges to execute arbitrary code by exploiting insecure OpenSSL configuration file loading. When a target user launches KeePassXC, malicious configuration planted in an unsecured path is loaded, enabling code execution in KeePassXC's security context. …

Sign in for full analysis, threat intelligence, and remediation guidance.

RemediationAI

Within 24 hours: Inventory all systems running KeePassXC and document current versions in use. Within 7 days: Restrict file system permissions on KeePassXC configuration directories to prevent unauthorized modification by low-privileged accounts; audit access logs for suspicious configuration file changes. …
