What the vulnerability does
The xShare plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.0.1. This is due to missing nonce validation on the 'xshare_plugin_reset()' function. This makes it possible for unauthenticated attackers to reset the plugin's settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
Explanation of Vulnerability in Simple Terms
xShare versions 1.0.1 and earlier are vulnerable to cross-site request forgery (CSRF) attacks. An attacker can craft a malicious webpage that, when visited by a logged-in xShare user, performs unwanted actions on their behalf without their knowledge. The attack requires the user to visit the attacker's page while authenticated to xShare. This vulnerability affects the integrity of user actions but does not expose sensitive data.
What an attacker can do
Perform unwanted actions on behalf of a logged-in user without their consent.
Potential impact on your site
Users' accounts can be manipulated to perform unintended actions if they visit malicious sites while logged in.
Conditions required to exploit
User must be logged into xShare and visit an attacker-controlled webpage.
