Readycheck to confirm it

SquirrelMail 1.4.6 and earlier versions are susceptible to a PHP local file inclusion vulnerability in functions/plugin.php if register_globals is enabled and magic_quotes_gpc is disabled. This allows remote attackers to execute arbitrary PHP code via a URL in the plugins array parameter.

Impact

An attacker can exploit this vulnerability to read sensitive files on the server, potentially leading to unauthorized access or information disclosure.

Fix

Upgrade Squirrelmail to a version higher than 1.4.6 or apply the necessary patches to fix the LFI vulnerability.

How to confirm it

Send: GET {{BaseURL}}/src/redirect.php?plugins[]=../../../../etc/passwd%00
Positive when: matches /root:[x*]:0:0/ AND status 200
