Deeper analysis

CVE-2022-2488 is an OS command injection vulnerability, tracked under CWE-78, that affects the WAVLINK WN535K2 and WN535K3 devices. It resides in the unknown processing of the file /cgi-bin/touchlist_sync.cgi, where manipulation of the IP argument permits injection of operating system commands. The flaw carries a CVSS 3.1 score of 8.0 reflecting adjacent-network attack vector, low complexity, and low required privileges.

An attacker positioned on the adjacent network who can supply a crafted IP value to the affected CGI endpoint can execute arbitrary commands on the device, resulting in full compromise of confidentiality, integrity, and availability. Public exploit code for the issue has been disclosed.

The EPSS score currently stands at 0.9332 with a recorded peak of 0.9702, indicating sustained exploitation interest. A 2024 Talos report (TALOS-2024-1999) further documents the vulnerability alongside the original disclosure references.
