CVE-2022-25441
Published: 18 March 2022
Summary
CVE-2022-25441 is a critical-severity OS Command Injection (CWE-78) vulnerability in Tenda Ac9 Firmware. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 5.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
Tenda AC9 firmware version 15.03.2.21 contains a remote command execution vulnerability in the SetIPTVCfg function, where the vlanid parameter is passed to a system command without proper sanitization. The flaw is tracked as CWE-78 and carries a CVSS 3.1 score of 9.8, reflecting network-accessible, unauthenticated attackability with high impact on confidentiality, integrity, and availability.
An unauthenticated attacker with network access can supply a crafted vlanid value to the affected endpoint and execute arbitrary operating-system commands on the device. Successful exploitation grants full control of the router, enabling actions such as configuration changes, traffic interception, or use of the device as an internal network foothold.
Public references consist of proof-of-concept material hosted on GitHub that demonstrates the injection vector; no vendor advisory or firmware patch information is included in the supplied sources. The EPSS score reached a peak of 0.1592 after disclosure before settling at the current value of 0.1271, indicating measurable post-publication exploitation interest.
