What is CVE-2021-25310?

The administration web interface of Belkin Linksys WRT160NL routers is susceptible to a command injection vulnerability that enables remote authenticated attackers to execute arbitrary system commands with root privileges. This security flaw arises from improper validation of the ui_language POST parameter sent to the apply.cgi endpoint through the do_upgrade_post function in mini_httpd. Note that this vulnerability poses a risk primarily to devices that are no longer supported by the vendor, leaving them unpatched and vulnerable to exploitation.
