A buffer overflow vulnerability exists in the dbm and shm session cache code of mod_ssl before 2.8.7-1.3.23 and Apache-SSL before 1.3.22+1.46. The vulnerability is due to improper memory initialization when using the i2d_SSL_SESSION function. Remote attackers can exploit this by presenting a large client certificate, signed by a trusted CA, which results in a large serialized session and triggers the overflow, potentially allowing arbitrary code execution.

This repository contains a single C exploit (764.c) and a README. The exploit is a classic remote buffer overflow targeting Apache mod_ssl (versions < 2.8.7) with vulnerable OpenSSL libraries, known as 'OpenFuck'. The exploit works by sending specially crafted SSL handshake messages to the target server, exploiting a buffer overflow to execute shellcode and spawn a remote shell. The code includes a large table of target architectures and function addresses, which must be matched to the target system (often requiring the attacker to know the address of the 'free' function in the target's httpd binary). The README provides compilation instructions and references to further documentation. The exploit is operational and requires network access to the target's HTTPS port (default 443). No hardcoded IPs or domains are present, but the exploit is highly configurable for different Linux distributions and Apache/OpenSSL versions.
