AI Analysis
Technical Summary
This vulnerability affects Shibby Tomato firmware up to version 1.28 in the UPS Service component, where improper handling in the sub_9068 function of tomatoups.cgi leads to a stack-based buffer overflow. The flaw can be exploited remotely without user interaction and requires low attack complexity and privileges. The vulnerability has a CVSS 4.0 score of 8.7, indicating high severity. The project is deprecated and replaced by FreshTomato, and no official fix or mitigation guidance is available from the vendor.
Potential Impact
Successful exploitation of this vulnerability could allow remote attackers to cause a stack-based buffer overflow, potentially leading to arbitrary code execution or denial of service on affected devices running Shibby Tomato up to version 1.28. Given the high CVSS score and remote attack vector, impacted devices are at significant risk if exposed to untrusted networks.
Mitigation Recommendations
No official patch or remediation is currently available as the affected Shibby Tomato versions are no longer supported and the project has been superseded by FreshTomato. Users are advised to upgrade to FreshTomato or another supported firmware to mitigate this vulnerability. Patch status is not yet confirmed — check the vendor advisory or project repositories for any updates or community fixes.
