Vulnerability Overview

The Task Manager Pro plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'Add a comment' section in versions up to, and including, 1.3.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user.

CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Reaching this weakness in Task Manager Pro - Task Management Plugin For Wordpress <= 1.3.1 takes a caller who can reach the endpoint. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.

Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For Task Manager Pro - Task Management Plugin For Wordpress the fix is 1.3.2: builds <= 1.3.1 are affected, anything from 1.3.2 onward is not.

Remediation

Update to version 1.3.2, or a newer patched version
