Exploitation Summary

EIP tracks 1 public exploit for CVE-2008-6971. PoCs published by Raz0r.

AI-analyzed exploit summary This exploit targets a weakness in SMF <= 1.1.5 on Windows-based servers, where the rand() function's predictability allows an attacker to reset the admin password by brute-forcing the seed value derived from a leaked MD5 hash. The PoC automates the process of predicting the validation code and generating a password reset link.

Description

The password reset functionality in Simple Machines Forum (SMF) 1.0.x before 1.0.14, 1.1.x before 1.1.6, and 2.0 before 2.0 beta 4 includes clues about the random number generator state within a hidden form field and generates predictable validation codes, which allows remote attackers to modify passwords of other users and gain privileges.
