Easy Forum join.php image Parameter XSS
Remote / Network Access Input Manipulation
Loss of Integrity
Exploit Unknown

- 漏洞描述

Easy Forum contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the Image URL field ('image' variable) upon submission to the 'join.php' script. This could allow a user to create a specially crafted URL that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity.

- 漏洞讨论

Easy Forum is prone to an HTML-injection vulnerability. This issue is due to a failure in the application to properly sanitize user-supplied input before using it in dynamically generated content.

Attacker-supplied HTML and script code would be executed in the context of the affected website, potentially allowing for the theft of cookie-based authentication credentials. An attacker could also exploit this issue to control how the site is rendered to the user; other attacks are also possible.

This issue is reported to affect version 2.5. Other versions may also be vulnerable.

- 漏洞利用

These issues can be exploited through use of a web client.

Example 'Image File' data sufficient to demonstrate this issue was provided:
javascript:alert(123) sometext.gif

- 解决方案

The vendor has re-released version 2.5 with a fix included, and has also released a patch to address this issue.
