Summary

CVE-2024-22663 is a critical-severity Command Injection (CWE-77) vulnerability in Totolink A3700R Firmware. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Unix Shell (T1059.004); ranked in the top 10.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

Deeper analysis

TOTOLINK A3700R routers running firmware version V9.1.2u.6165_20211012 contain a command injection vulnerability in the setOpModeCfg function. The flaw is tracked as CVE-2024-22663, carries a CVSS 3.1 score of 9.8, and is categorized under CWE-77. It allows unauthenticated network callers to supply crafted input that is passed directly to a system command interpreter.

An attacker with no credentials or user interaction can send a malicious request to the affected device's web management interface and execute arbitrary operating-system commands. Successful exploitation grants complete control over the device, enabling actions such as configuration changes, traffic interception, or persistence mechanisms.

Public proof-of-concept code demonstrating the setOpModeCfg injection has been published on GitHub. The EPSS score rose from a low baseline to a peak of 0.6009 on 2025-01-22 before receding to its current value of 0.0476, indicating a period of increased exploitation interest after disclosure. No vendor advisory or patch information is referenced in the available sources.
