AI Analysis

Impact

An OS command injection flaw exists in the new_qoslimit_start function of Shibby Tomato firmware 1.28.0000. Manipulating the new_qoslimit_enable argument allows an attacker to inject arbitrary operating system commands into the router's process. The flaw can be exploited remotely, giving attackers the ability to run commands with the device's operating‑system privileges, potentially compromising confidentiality, integrity, and availability.

Affected Systems

Shibby Tomato routers running firmware version 1.28.0000 are affected. The vulnerability resides in /etc/qoslimit, and no later releases are indicated as safe in the available data.

Risk and Exploitability

The CVSS score of 8.6 denotes high severity. EPSS data is not available, but a publicly available exploit demonstrates that attackers can use this flaw. The vulnerability is not listed in CISA's KEV catalog. Because the flaw permits remote OS command execution, operators who have not applied a patch face a significant risk of total device compromise.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade the router firmware to the latest Shibby Tomato release or transition to FreshTomato, which removes the vulnerable code.
  • Restrict access to the new_qoslimit_* endpoints by allowing only authenticated and privileged users, and block the administrative interface from external networks.
  • Monitor the router's logs for attempts to alter qoslimit settings and review them regularly for anomalous activity that could indicate injection attempts.
