CVE-2025-34102: CWE-89 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in Crypttech CryptoLog
A remote code execution vulnerability exists in CryptoLog (PHP version, discontinued since 2009) due to a chained exploitation of SQL injection and command injection vulnerabilities. An unauthenticated attacker can gain shell access as the web server user by first exploiting a SQL injection flaw in login.php to bypass authentication, followed by command injection in logshares_ajax.php to execute arbitrary operating system commands. The login bypass is achieved by submitting crafted SQL via the user POST parameter. Once authenticated, the attacker can abuse the lsid POST parameter in the logshares_ajax.php endpoint to inject and execute a command using $(...) syntax, resulting in code execution under the web context. This exploitation path does not exist in the ASP.NET version of CryptoLog released since 2009.
AI Analysis
Technical Summary
This vulnerability in CryptoLog (PHP version) enables remote code execution through a two-step exploitation: first, an unauthenticated attacker exploits an SQL injection flaw in login.php by submitting crafted SQL via the user POST parameter to bypass authentication. Then, with authenticated access, the attacker abuses a command injection vulnerability in the lsid POST parameter of logshares_ajax.php, using shell command substitution syntax $(...) to execute arbitrary commands under the web server's privileges. The ASP.NET version of CryptoLog released since 2009 does not contain this vulnerability.
Potential Impact
Successful exploitation allows an unauthenticated attacker to gain shell access as the web server user, leading to full remote code execution on the affected system. This compromises the confidentiality, integrity, and availability of the server and potentially the broader network environment. Given the critical CVSS score of 9.3, the impact is severe.
Mitigation Recommendations
No official patch or remediation is currently available for this vulnerability, as the PHP version of CryptoLog has been discontinued since 2009 and no patch links are provided. Users should consider migrating to the ASP.NET version of CryptoLog released after 2009, which does not contain this vulnerability. Until a fix is available, affected systems should be isolated or decommissioned to prevent exploitation.
