medium Nessus Plugin ID 63334
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote web server hosts an auditing application that is affected by multiple vulnerabilities.


According to its self-reported version number, the installation of Snare Agent for Linux hosted on the remote web server is affected by multiple vulnerabilities in the optionally configured web interface:

- The web interface discloses a hashed password for remote logins. An attacker can view the page source at /remote and see the hashed password in the 'RemotePassword' field. (CVE-2011-5247)

- The web interface suffers from a cross-site scripting vulnerability because the application fails to sanitize input passed via logged events. An attacker could create a specially crafted request that would execute arbitrary script code in a user's browser.

- The web interface suffers from a cross-site request forgery (CSRF) vulnerability because it fails to properly implement the 'ChToken' parameter used to prevent CSRF attacks. (CVE-2011-5250)


Upgrade to version 1.7.0 / 2.0.0 or later.
