Technical Summary
The vulnerability CVE-2026-10066 involves a stack-based buffer overflow in the sub_9068 function of the tomatoups.cgi file, part of the UPS Service component in Shibby Tomato firmware versions 1.0 through 1.28. This flaw allows remote attackers to cause a buffer overflow, potentially leading to code execution or denial of service. The project is no longer maintained and has been replaced by FreshTomato, and no official fix or patch has been released for this vulnerability.
Potential Impact
Successful exploitation of this vulnerability could allow a remote attacker to execute arbitrary code or cause a denial of service on affected devices running Shibby Tomato firmware up to version 1.28.
