Deeper analysis
CVE-2022-35537 is a command-injection vulnerability in the wireless.cgi component of several WAVLINK wireless routers, specifically the WN572HP3, WN533A8, WN530H4, WN535G3, and WN531P3 models. The flaw stems from missing input filtering on the mac_5g and Newname parameters, which are processed when the device renders the /wifi_mesh.shtml page.
An unauthenticated attacker with network access can supply crafted values for these parameters to execute arbitrary operating-system commands on the device. Successful exploitation grants full control over the router, allowing arbitrary code execution with impacts across confidentiality, integrity, and availability.
The associated EPSS score rose from a low baseline to a peak of 0.0876 on 2025-01-22 before receding to its current value of 0.0187, indicating a period of increased exploitation interest well after the original disclosure.
