# CVE-2013-10043

> 9.5 CRITICAL · 🧪 PoC

## Beschreibung

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.

## Schwachstellen-Klasse

- **CWE-434** — Unrestricted Upload of File with Dangerous Type
  The product allows the upload or transfer of dangerous file types that are automatically processed within its environment.
- **CWE-89** — Improper Neutralization of Special Elements used in an SQL Command
  The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as…
