What an attacker can do

The source says a remote unauthenticated attacker can submit a failed login with a crafted username that is written to the error log and executes JavaScript in an administrator's browser when the logs are viewed, allowing the attacker to create accounts or execute code on the server with the administrator's privileges. Vendor/CNA’s CVSS 4.0 assessment (base score 5.3/10) rates confidentiality, integrity and availability impact as none.
