Plesk Obsidian, a widely used web hosting and server management platform, is vulnerable to a flaw that allows attackers to disable its web interface.

## Technical details

The flaw is categorized under CWE-400 (Uncontrolled Resource Consumption) and CWE-606 (Unchecked Input for Loop Condition). An unauthenticated remote attacker can send a crafted request containing a malicious payload that causes the web interface to enter an infinite reload loop, characterized by continuous 'Bad Request' responses.
