Summary

CVE-2024-2353 is a high-severity OS Command Injection (CWE-78) vulnerability in Totolink X6000R Firmware. Its CVSS base score is 8.8 (High).

Deeper analysis

A critical OS command injection vulnerability (CWE-78) affects the Totolink X6000R router running firmware 9.4.0cu.852_20230719. The flaw resides in the setDiagnosisCfg function of /cgi-bin/cstecgi.cgi within the shttpd component; unsanitized input to the ip argument is passed directly to the operating system, enabling arbitrary command execution.

An attacker with low-privileged network access can exploit the issue remotely without user interaction, achieving full control over confidentiality, integrity, and availability on the device. A working proof-of-concept has been publicly released, and the vendor did not respond to early disclosure.

EPSS scores rose from a low baseline to a peak of 0.1232 in December 2025 before receding to the current 0.0626, indicating measurable post-disclosure interest in the exploit. No official patches or mitigation guidance have been issued.
