Description

A remote buffer-overflow vulnerability affects Savant Web Server. This issue occurs because the application fails to validate the length of user-supplied strings before copying them into finite process buffers.

A remote attacker may leverage this issue to execute arbitrary code with the privileges of the affected webserver. This issue may facilitate unauthorized access or privilege escalation.
