CVE-2025-34102Public exploitNetwork attack vector

Unauthenticated RCE via chained SQL and command injection

Published Jul 10, 2025 · Updated Apr 7, 2026

Command injection in Crypttech CryptoLog PHP releases before the 2009 ASP.NET rewrite allows remote attackers to execute OS commands. login.php concatenates the user POST parameter into an SQL query, enabling authentication bypass; logshares_ajax.php then passes the lsid value into a shell command without neutralization. No credentials are required, and the chain executes commands in the web server context on affected Linux deployments.
