Vulnerability Overview

The Social Sharing Plugin – Sassy Social Share plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's shortcode(s) in all versions up to, and including, 3.3.60 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Technical Analysis

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-179: Incorrect Behavior Order: Early Validation

The product validates input before applying protection mechanisms that modify the input, which could allow an attacker to bypass the validation via dangerous inputs that only arise after the modification.

Remediation

Update to version 3.3.61, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: Social Sharing Plugin 3.3.61 closes this, and updating the plugin is the step that ends it.
