Vulnerability Information

Vulnerability Published: 2010-11-30
Patch Published: 2010-11-30
CVE [?]: CVE-2010-4279
CPE [?]: cpe:/a:artica:pandora_fms

Synopsis

A web console on the remote host is affected by an authentication bypass vulnerability.

Description

The Pandora FMS console hosted on the remote web server is affected by an authentication bypass vulnerability. The 'auto login (hash) password' feature allows third parties to authenticate using a combination of username and a shared secret. This shared secret is undefined by default, which means it is possible to authenticate solely by providing the hash of a valid username.

A remote attacker can exploit this issue to access the console as admin.

This version of Pandora FMS is also affected by other vulnerabilities; however, Nessus has not tested for those issues.

Solution

Apply the security fix for Pandora FMS 3.1, or upgrade to version 3.1.1 or later.

Public Exploits
