Shenzhen Tenda W30E V2 firmware versions up to and including V16.01.0.19(5037) allow account passwords to be changed through the maintenance interface without requiring verification of the existing password. This enables unauthorized password changes when access to the affected endpoint is obtained.

The Sunshine Photo Cart: Free Client Photo Galleries for Photographers plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 3.4.11. This is due to the plugin not properly validating a user-supplied key. This makes it possible for authenticated attackers, with Subscriber-level access and above, to change arbitrary user's passwords through the password reset functionality, including administrators, and leverage that to reset the user's password and gain access to their account.

The Frontend Login and Registration Blocks plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 1.0.7. This is due to the plugin not properly validating a user's identity prior to updating a password. This makes it possible for authenticated attackers, with Subscriber-level access and above, to change arbitrary user's passwords, including administrators, and leverage that to gain access to their account.

The LevelOne WBR-6012 router's web application has a vulnerability in its firmware version R0.40e6, allowing attackers to change the administrator password and gain higher privileges without the current password.

EventSentry versions prior to 6.0.1.20 contain an unverified password change vulnerability in the account management functionality of the Web Reports interface. The password change mechanism does not require validation of the current password before allowing a new password to be set. An attacker who gains temporary access to an authenticated user session can change the account password without knowledge of the original credentials. This enables persistent account takeover and, if administrative accounts are affected, may result in privilege escalation.
