[TLP:CLEAR] Zyxel fixes a high-severity vulnerability
Zyxel fixes a high-severity vulnerability in the firmware of some of its access points (AP). The affected models and the corresponding fixed firmware versions can be found at [1].
An authenticated remote attacker with administrator rights is, due to a path traversal vulnerability in the CGI program 'file_upload-cgi' of some APs, allowed to delete specific files, including configuration files, on the vulnerable device [1]. However, successful exploitation is conditional on prior compromise of administrator credentials.
