High
Published: Translated: NVD NIST

Summary

QNX Neutrino RTOS 6.3.0 ships /etc/rc.d/rc.local with world-writable permissions, allowing local users to modify the file and execute arbitrary code at system startup.

Risk Assessment

The risk is that a local attacker can escalate privileges by modifying the startup script, leading to persistent system compromise and arbitrary code execution on every boot.

Recommendation

Immediately change permissions of /etc/rc.d/rc.local to 755 (or more restrictive) and verify the file has not been tampered with by unauthorized users.
