7.5
CVSS v3.1
Official Description
The loadUserSettings function in Load.php in Simple Machines Forum (SMF) before 1.1.13, and 2.x before 2.0 RC5, does not properly handle invalid login attempts, which might make it easier for remote attackers to obtain access or cause a denial of service via a brute-force attack.
Technical Analysis
CVE-2011-1128 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.
