Exploitation Summary

EIP tracks 2 public exploits for CVE-2013-10043. PoCs published by xistence, including Metasploit module exploits/linux/http/astium_sqli_upload.

AI-analyzed exploit summary This exploit leverages SQL injection to bypass authentication in Astium VoIP PBX, then uploads a PHP script to modify the config.php file with a reverse shell payload. The exploit triggers a sudo service reload to execute the payload as root, then cleans up the config.php file to restore functionality.

Description

A vulnerability exists in OAstium VoIP PBX astium-confweb-2.1-25399 and earlier, where improper input validation in the logon.php script allows an attacker to bypass authentication via SQL injection. Once authenticated as an administrator, the attacker can upload arbitrary PHP code through the importcompany field in import.php, resulting in remote code execution. The malicious payload is injected into /usr/local/astium/web/php/config.php and executed with root privileges by triggering a configuration reload via sudo /sbin/service astcfgd reload. Successful exploitation leads to full system compromise.
