Wordapp <= 1.6.0 - Authorization Bypass through Use of Insufficiently Unique Cryptographic Signature
Source: CVE Program / CVE List V5
Vulnerability Description
The Wordapp plugin for WordPress is vulnerable to authorization bypass due to an use of insufficiently unique cryptographic signature on the 'wa_pdx_op_config_set' function in versions up to, and including, 1.6.0. This makes it possible for unauthenticated attackers to the plugin to change the 'validation_token' in the plugin config, providing access to the plugin's remote control functionalities, such as creating an admin access URL, which can be used for privilege escalation.
