info:
|
|
name: WordPress W3 Total Cache <2.1.4 - Cross-Site Scripting
|
|
author: theamanrawat
|
|
severity: medium
|
|
description: |
|
|
WordPress W3 Total Cache plugin before 2.1.4 is susceptible to cross-site scripting within the extension parameter in the Extensions dashboard, which is output in an attribute without being escaped first. This can allow an attacker to convince an authenticated admin into clicking a link to run malicious JavaScript within the user's web browser, which could lead to full site compromise.
|
|
remediation: Fixed in version 2.1.4.
