CVE-2022-27078
Published: 24 March 2022
Summary
CVE-2022-27078 is a critical-severity Command Injection (CWE-77) vulnerability in Tenda M3 Firmware. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 5.4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
Tenda M3 firmware version 1.10 V1.0.0.12(4856) contains a command-injection flaw (CWE-77) in the /goform/setAdInfoDetail endpoint. The vulnerability received a CVSS 3.1 score of 9.8, reflecting network attack vector, low complexity, and no required credentials or user interaction, with high impact on confidentiality, integrity, and availability.
An unauthenticated attacker with network access can supply crafted input to the affected endpoint and execute arbitrary operating-system commands on the device. Successful exploitation grants the attacker full control over the router, enabling actions such as configuration changes, traffic interception, or use of the device as an internal network pivot.
Public proof-of-concept material is available in GitHub repositories that demonstrate the injection. The associated EPSS score rose from a low baseline to a peak of 0.1908 (currently 0.1434), indicating measurable post-disclosure exploitation interest that warrants renewed attention for any exposed Tenda M3 instances.
