CVE-2025-34102 is a remote code execution vulnerability affecting the discontinued PHP version of CryptoLog. The issue is exploitable through a chained attack path involving an authentication-bypass SQL injection in login.php and a subsequent OS command injection in logshares_ajax.php. An unauthenticated attacker can submit crafted SQL in the user POST parameter to bypass authentication, then send a malicious lsid POST parameter to logshares_ajax.php using shell substitution syntax such as $(...) to execute arbitrary operating system commands. Successful exploitation yields shell access in the context of the web server user. The described attack path does not affect the ASP.NET version of CryptoLog released since 2009.

This repository contains a single Metasploit module (modules/exploits/linux/http/crypttech_cryptolog_login_exec.rb) targeting the PHP version of Crypttech CryptoLog. The exploit leverages two vulnerabilities: a SQL injection in login.php to bypass authentication and obtain a valid session, and a command injection in logshares_ajax.php to execute arbitrary commands as the web user. The module is weaponized, using a customizable Python Meterpreter reverse shell payload. The exploit is unauthenticated, requiring only network access to the CryptoLog web interface. The code is well-structured, following Metasploit conventions, and registers options for the target URI and port. The main attack vector is network-based, and the endpoints /cryptolog/login.php and /cryptolog/logshares_ajax.php are fingerprintable. The exploit targets CVE-2025-34102 and is effective against the PHP version of CryptoLog prior to its rewrite in ASP.NET.
