7.5
CVSS v3.1
Official Description
load_prefs.php and supporting include files in SquirrelMail 1.0.4 and earlier do not properly initialize certain PHP variables, which allows remote attackers to (1) view sensitive files via the config_php and data_dir options, and (2) execute arbitrary code by using options_order.php to upload a message that could be interpreted as PHP.
Technical Analysis
CVE-2001-1159 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
