Summary

CVE-2024-0293 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 NTDS (T1003.003); ranked in the top 8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

A critical OS command injection vulnerability exists in the Totolink LR1200GB router firmware version 9.1.0u.6619_B20230130. The flaw resides in the setUploadSetting function of /cgi-bin/cstecgi.cgi, where unsanitized input to the FileName argument allows arbitrary command execution. It is tracked as CVE-2024-0293 with CWE-78 and carries a CVSS 3.1 score of 6.3.

An authenticated remote attacker can supply a crafted FileName value to the affected CGI endpoint and execute operating-system commands on the device. Public exploit code has been released, enabling attackers to achieve limited confidentiality, integrity, and availability impacts without user interaction.

No vendor patch or mitigation guidance has been issued; the manufacturer did not respond to disclosure. The associated EPSS score rose from a low baseline to a peak of 0.0656 on 2025-01-22 before receding, indicating increased exploitation interest well after the January 2024 publication.

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and evaluation can discover missing or incorrect command sanitization during development.

Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.

Least privilege reduces the permissions available to any process that could be subverted by injected commands.

Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.

Secure engineering principles require proper neutralization of untrusted input before command construction.

PR.PS-06 mostly match
blocks

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.

PR.PS-02 partial match
blocks

Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
