MyBB < 1.6.17 Multiple Vulnerabilities

high Nessus Network Monitor Plugin ID 9123

Synopsis

The remote web server is running a PHP application that is vulnerable to multiple attack vectors.

Description

Versions of MyBB (MyBulletinBoard) prior to 1.6.17 are affected by the following vulnerabilities :

- Multiple unspecified flaws exist that allow stored cross-site scripting (XSS) attacks. These flaws exist because the program does not validate input before returning it to users. This may allow an authenticated remote attacker to create a specially crafted request that would execute arbitrary script code in a user's browser session within the trust relationship between their browser and the server.
- A flaw in ACP login as HTTP requests do not require multiple steps, explicit confirmation, or a unique token when performing certain sensitive actions. By tricking a user into following a specially crafted link, a context-dependent attacker can perform a Cross-Site Request Forgery (CSRF / XSRF) attack causing the victim to perform unspecified actions.
- A flaw exists that is due to the cache handler using 'var_export' without encoding checks. This may allow an attacker to have an unspecified impact.

Solution

Upgrade to MyBB version 1.6.17 or later.
