The kluser is able to interact with the kav4fs-control binary in Kaspersky Anti-Virus for Linux File Server before Maintenance Pack 2 Critical Fix 4 (version 8.0.4.312). By abusing the quarantine read and write operations, it is possible to elevate the privileges to root.

Security readout for executives and security teams

CVE-2017-9811 is a local privilege escalation issue in Kaspersky Anti-Virus for Linux File Server. A low-privileged kluser account could abuse quarantine read/write operations through kav4fs-control to gain root privileges. This matters most where the affected product still protects Linux file servers. Likely exposure is limited to systems running Kaspersky Anti-Virus for Linux File Server versions before 8.0.4.312. The source bundle does not list CPEs or a complete affected-version matrix, so teams should confirm exact installed builds against vendor guidance. Prioritize remediation where this product remains deployed on file servers with local user access. Root escalation on security infrastructure can undermine host integrity, but the provided evidence does not show current active exploitation. Mitigation focus: Upgrade affected installations to Maintenance Pack 2 Critical Fix 4, version 8.0.4.312, or later.; Inventory Linux file servers running Kaspersky Anti-Virus for Linux File Server.; Check Kaspersky/vendor guidance for any supported compensating controls..
