## What is CVE-2013-10043?

CVE-2013-10043 is a critical SQL injection vulnerability in Astium VoIP PBX, published on 31 Jul 2025. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official 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.

Weakness: CWE-89 (Improper Neutralization of Special Elements used in an SQL Command), CWE-434 (Unrestricted Upload of File with Dangerous Type)
