Zero X has reported some vulnerabilities in K+B-Bestellsystem, which can be exploited by malicious people to compromise a vulnerable system.
Input passed to the "domain" and "tld" parameters in kb_whois.cgi when the "action" parameter is set to "check_owner" is not properly sanitised before being used. This can be exploited to inject arbitrary shell commands via the ";" character.
Solution: Edit the source code to ensure that input is properly sanitised.
