Summary

CVE-2024-0292 is a medium-severity OS Command Injection (CWE-78) vulnerability in Totolink Lr1200Gb Firmware. Its CVSS base score is 6.3 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 18.4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

Deeper analysis

A critical OS command injection vulnerability, tracked as CVE-2024-0292 and assigned CWE-78, affects the Totolink LR1200GB router running firmware 9.1.0u.6619_B20230130. The flaw resides in the setOpModeCfg function within /cgi-bin/cstecgi.cgi, where unsanitized input to the hostName argument allows arbitrary command execution.

An authenticated remote attacker with low privileges can supply a crafted hostName value to the CGI endpoint and execute operating system commands on the device. Successful exploitation yields limited read, write, and disruption capabilities on the affected router without requiring user interaction.

Public exploit code has been released via GitHub and Vuldb, and the vendor did not respond to early disclosure notifications. The EPSS score rose materially from a low baseline to a peak of 0.0656 on 2025-01-22 before receding to the current value of 0.0151, indicating post-disclosure exploitation interest that warrants renewed attention.

Mitigating Controls

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

SC-27 Platform-independent Applications
addresses: CWE-78

Platform-independent apps typically execute inside a managed runtime or sandbox that restricts direct OS command execution, reducing the ability to exploit OS command injection.

SI-10 Information Input Validation
addresses: CWE-78

Validates inputs to block special elements that would alter OS command execution.
