A remote buffer overflow vulnerability in Shibby Tomato 1.28 exposes the system to potential memory corruption and unauthorized control.

This is a stack-based buffer overflow vulnerability residing in the sub_42537C function within the Scheduler Name Handler component. An authenticated attacker can exploit this flaw remotely to trigger memory corruption.

The vulnerability carries a CVSS score of 8.8, indicating a high level of risk. Successful exploitation could lead to system instability, denial of service, or arbitrary code execution, potentially compromising the integrity of the network infrastructure managed by the router.

Immediate Action: As the Shibby Tomato project is no longer maintained, users must migrate to a supported alternative such as FreshTomato to remediate this risk.

Proactive Monitoring: Review system logs for unusual crashes or unexpected behavior within the scheduler process.

Compensating Controls: Restrict access to the router management interface to trusted internal networks only.

Public Exploit Available: Unknown

Given that Shibby Tomato is an unmaintained project, there is no vendor patch available. Security teams should prioritize replacing any devices running this firmware with a supported version of FreshTomato to eliminate this and future security risks.
