CVE-2026-7690

Description

A weakness has been identified in Wavlink WL-WN570HA1 R70HA1 V1410_221110. This issue affects the function set_sys_adm of the file /cgi-bin/adm.cgi. This manipulation of the argument Username causes command injection. It is possible to initiate the attack remotely. The exploit has been made available to the public and could be used for attacks. Once again the vendors acted very professional and confirms, "that the WN570HA1 firmware version R70HA1 V1410_221110 has been removed from our website." This vulnerability only affects products that are no longer supported by the maintainer.
