A flaw was found in Plesk Obsidian. A remote attacker, without needing to authenticate, can send a specially crafted request to the get_password.php endpoint. This malicious request causes the web interface to continuously reload, leading to a Denial of Service (DoS) condition. This renders the service unavailable to legitimate users, impacting the availability of the Plesk Obsidian instance.

Plesk Obsidian versions 8.0.1 through 18.0.73 are vulnerable to a Denial of Service (DoS) condition. The vulnerability exists in the get_password.php endpoint, where a crafted request containing a malicious payload can cause the affected web interface to continuously reload, rendering the service unavailable to legitimate users. An attacker can exploit this issue remotely without authentication, resulting in a persistent availability impact on the affected Plesk Obsidian instance.
