Technical details
The vulnerability exists in the checkLogin function within libwebcmn.so and networkDiag.cgi, which validates session cookies based solely on a cleartext username without cryptographic integrity checks or random identifiers. An unauthenticated remote attacker can forge a session cookie containing a guessed default account name (such as "Admin" or "sftp_user") to satisfy the login check and gain authenticated access, chaining into arbitrary root command execution.
