Tenable Nessus < 8.5.0 Multiple Vulnerabilities (TNS-2019-04)

medium Nessus Plugin ID 126627

Language:

Synopsis

Tenable Nessus running on the remote host is affected by multiple vulnerabilities.

Description

According to its self-reported version, the Tenable Nessus application running on the remote host is prior to 8.5.0.
It is, therefore, affected by multiple vulnerabilities:

 - A reflected XSS vulnerability due to improper validation of user-supplied input. An unauthenticated, remote attacker could potentially exploit this vulnerability via a specially crafted request to execute arbitrary script code in a users browser session. (CVE-2019-3961)

 - A content injection vulnerability. An authenticated, local attacker could exploit this vulnerability by convincing another targeted Nessus user to view a malicious URL and use Nessus to send fraudulent messages. Successful exploitation could allow the authenticated adversary to inject arbitrary text into the feed status, which will remain saved post session expiration. (CVE-2019-3962)

Solution

Upgrade to Tenable Nessus version 8.5.0 or later.
