Summary

CVE-2022-25079 is a critical-severity OS Command Injection (CWE-78) vulnerability in Totolink A810R Firmware. Its CVSS base score is 9.8 (Critical).

Operationally, ranked in the top 9.4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

Deeper analysis

TOTOLink A810R firmware version V4.1.2cu.5182_B20201026 contains a command injection vulnerability (CWE-78) in the Main function. The flaw permits unauthenticated remote attackers to supply arbitrary operating-system commands through the QUERY_STRING parameter, yielding a CVSS 3.1 base score of 9.8.

An attacker with network access to the device can therefore achieve full command execution, resulting in complete compromise of confidentiality, integrity, and availability without any user interaction or credentials.

Public references consist solely of a proof-of-concept disclosure on GitHub; no vendor advisory or patch information is provided. The associated EPSS score remains flat at 0.0566 with no material increase since publication.
