Improper authentication vulnerability in TP-Link WA850RE (httpd modules) allows unauthenticated attackers to download the configuration file.This issue affects: ≤ WA850RE V2_160527, ≤ WA850RE V3_160922.

An authentication bypass vulnerability within the HTTP handling of the DS configuration service in TP-Link Tapo C520WS v2.6 was identified, due to inconsistent parsing and authorization logic in JSON requests during authentication check. An unauthenticated attacker can append an authentication-exempt action to a request containing privileged DS do actions, bypassing authorization checks. Successful exploitation allows unauthenticated execution of restricted configuration actions, which may result in unauthorized modification of device state.

Authentication bypass in the password recovery feature of the local web interface across multiple VIGI camera models allows an attacker on the LAN to reset the admin password without verification by manipulating client-side state. Attackers can gain full administrative access to the device, compromising configuration and network security.
