Administrators can help protect affected systems from external attacks by using a solid firewall strategy.

Administrators are advised to monitor affected systems.

Exploitation

To exploit this vulnerability, an attacker must send a request that submits malicious input to the targeted system, making exploitation more difficult in environments that restrict network access from untrusted sources.
