CVE-2023-28140

Estado: ModificadaAlta (7)—

An Executable Hijacking condition exists in the Qualys Cloud Agent for Windows platform in versions before 4.5.3.1. Attackers may load a malicious copy of a Dependency Link Library (DLL) via a local attack vector instead of the DLL that the application was expecting, when processes are running with escalated privileges. This vulnerability is bounded only to the time of uninstallation and can only be exploited locally.

At the time of this disclosure, versions before 4.0 are classified as End of Life.
