Deeper analysis

CVE-2022-37149 is a command injection vulnerability, tracked under CWE-78, that affects the WAVLINK WL-WN575A3 wireless range extender running firmware RPT75A3.V4300.201217. The flaw resides in the adm.cgi endpoint and is triggered when unsanitized input is processed through the username parameter, allowing operating-system command execution.

An unauthenticated attacker with network access can supply a crafted username value to adm.cgi and execute arbitrary commands on the device. The vulnerability carries a CVSS 3.1 score of 9.8, reflecting that no authentication, user interaction, or special network positioning is required to obtain full control over the affected device.

Public references consist of a GitHub repository that documents the issue and supplies proof-of-concept details; no vendor advisory or firmware patch information is included in the available sources.

The EPSS score for this CVE rose from a low baseline after disclosure to a peak of 0.4207 on 2025-01-22 before receding to its current value of 0.1331, indicating a later surge in exploitation interest that warrants renewed attention.
