CVE-2004-1767

Vulnerability

The kernel in Solaris 2.6, 7, 8, and 9 supports loadable kernel modules (LKMs). A vulnerability exists that allows an unprivileged local user to load arbitrary kernel modules, possibly via the modload function [1]. This bypasses intended access controls.

Exploitation

An attacker with local user access can load a malicious kernel module using the modload command or similar mechanism. No special privileges are required beyond a local shell account [1].

Impact

Successful exploitation allows the attacker to gain root privileges by executing arbitrary code in kernel context [1]. This results in full compromise of the system.

Mitigation

No official patch or workaround is documented in the available reference [1]. The CERT note indicates vendor information but no solution. Users should restrict local access and monitor for unauthorized module loading.
