Synopsis

The remote FreeBSD host is missing a security-related update.

Description

The phpMyAdmin development team reports : Summary XSS in Designer feature Description A Cross-Site Scripting vulnerability was found in the Designer feature, where an attacker can deliver a payload to a user through a specially crafted database name. Severity We consider this attack to be of moderate severity. Summary File inclusion and remote code execution attack Description A flaw has been discovered where an attacker can include (view and potentially execute) files on the server.

The vulnerability comes from a portion of code where pages are redirected and loaded within phpMyAdmin, and an improper test for whitelisted pages.

An attacker must be authenticated, except in these situations :

- $cfg['AllowArbitraryServer'] = true: attacker can specify any host he/she is already in control of, and execute arbitrary code on phpMyAdmin

- $cfg['ServerDefault'] = 0: this bypasses the login and runs the vulnerable code without any authentication Severity We consider this to be severe. Mitigation factor Configuring PHP with a restrictive `open_basedir` can greatly restrict an attacker's ability to view files on the server. Vulnerable systems should not be run with the phpMyAdmin directives $cfg['AllowArbitraryServer'] = true or $cfg['ServerDefault'] = 0

Solution

Update the affected package.
