Published: Translated: NVD NIST

Summary

The host-deny.sh script in OSSEC before version 2.8.1 writes to temporary files with predictable filenames without verifying ownership. This allows local users to modify access restrictions in hosts.deny and gain root privileges by creating the temporary files before automatic IP blocking occurs.

Risk Assessment

The organization may be exposed to unauthorized access to the system, potentially leading to privilege escalation and damage to the IT infrastructure.

Recommendation

It is recommended to update OSSEC to version 2.8.1 or later to eliminate this vulnerability and implement additional security measures to protect against local attacks.
