AI Analysis
Technical Summary
This vulnerability affects the Shibby Tomato firmware versions up to 1.28.0000 in the apcupsd component, specifically in the main function of www/apcupsd/tomatodata.cgi. An attacker can remotely trigger an out-of-bounds write condition, potentially leading to memory corruption. The vulnerability has a CVSS 4.0 base score of 8.7, indicating high severity with network attack vector, low attack complexity, no privileges required, no user interaction, and high impacts on confidentiality, integrity, and availability. Exploits are publicly available. The project is no longer maintained and has been superseded by FreshTomato. No official fix or patch has been documented.
Potential Impact
Successful exploitation allows remote attackers to perform out-of-bounds writes, which can lead to memory corruption and potentially compromise system confidentiality, integrity, and availability. Given the high CVSS score and remote attack vector, this vulnerability poses a significant risk to affected devices running Shibby Tomato firmware up to 1.28.0000.
Mitigation Recommendations
No official patch or remediation is currently available for this vulnerability. Since the Shibby Tomato project is superseded by FreshTomato, users are advised to migrate to FreshTomato firmware or other maintained alternatives. Until then, restricting network access to the vulnerable component and disabling the apcupsd service if not required may reduce exposure. Monitor vendor advisories for any future updates.
