CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to improper filtering of HTML code from user-supplied input. A remote authenticated user can cause arbitrary scripting code execution by the target authenticated user's browser. The code will originate from the site running the Tenable Nessus software. As a result, the code will be able to access the target user's cookies, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.

Mitigation

The vendor has issued a fix (6.8).
