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.
An NTFS Junction condition exists in the Qualys Cloud Agent
for Windows platform in versions before 4.8.0.31. Attackers may write files to
arbitrary locations via a local attack vector. This allows attackers to assume
the privileges of the process, and they may delete or otherwise on unauthorized
files, allowing for the potential modification or deletion of sensitive files
limited only to that specific directory/file object. This vulnerability is
bounded to the time of installation/uninstallation and can only be exploited locally.
At the time of this disclosure, versions before 4.0 are
classified as End of Life.
A Race Condition exists in the Qualys Cloud Agent for Windows
platform in versions from 3.1.3.34 and before 4.5.3.1. This allows attackers to
escalate privileges limited on the local machine during uninstallation of the
Qualys Cloud Agent for Windows. Attackers may gain SYSTEM level privileges on
that asset to run arbitrary commands.
At the time of this disclosure, versions before 4.0 are classified as End
of Life.
