Analyst readout for executives and security teams
Plain-English summary
This is an old local-permission flaw in Kaspersky Anti-Virus for Unix/Linux File Servers. A user with local access could tamper with antivirus logs or license files, potentially disrupting updates and obscuring activity. It is not a remote compromise based on the provided sources.
Executive priority
Treat as a legacy exposure cleanup item unless affected servers are shared or still security-critical. Prioritize confirming whether the product exists in the environment, then remove, upgrade, or harden it.
Technical view
Kaspersky Anti-Virus for Unix/Linux File Servers 5.0-5 created world-writable log and license directories. Local users could delete logs, abuse a symlink involving kavmonitor.log to append to arbitrary files, or delete license keys and disrupt keepup2date execution.
Likely exposure
Exposure appears limited to systems still running Kaspersky Anti-Virus for Unix/Linux File Servers 5.0-5 with default insecure directory permissions and local untrusted users.
Exploitation context
The provided bundle does not show CISA KEV listing or active exploitation. It includes historical public references from 2005. The attack requires local user access, so risk depends heavily on shared-server use and account isolation.
Researcher notes
The CVE data is sparse: no CVSS, CWE, or structured affected CPEs are provided. The core issue is unsafe default filesystem permissions enabling local tampering and symlink abuse, not a network-facing vulnerability.
Mitigation direction
- Identify any remaining Kaspersky Anti-Virus for Unix/Linux File Servers 5.0-5 installations.
- Check vendor guidance or upgrade paths for corrected permissions and supported versions.
- Restrict write permissions on antivirus log and license directories per vendor guidance.
- Limit local shell access to trusted administrators only.
- Monitor for missing antivirus logs, license deletion, or update failures.
Validation and detection
- Inventory Unix/Linux file servers for the affected Kaspersky product and version.
- Inspect log and license directory ownership and write permissions.
- Check whether kavmonitor.log can be replaced or influenced by untrusted users.
- Review antivirus update logs for keepup2date failures.
- Confirm compensating controls restrict local untrusted user access.
