PRTG Network Monitor before 18.2.40.1683 allows remote unauthenticated attackers to create users with read-write privileges (including administrator). A remote unauthenticated user can craft an HTTP request and override attributes of the 'include' directive in /public/login.htm and perform a Local File Inclusion attack, by including /api/addusers and executing it. By providing the 'id' and 'users' parameters, an unauthenticated attacker can create a user with read-write privileges (including administrator).
Impact
Unauthenticated attackers can create administrator users with full privileges via local file inclusion, leading to complete compromise of the monitoring system and access to network infrastructure.
Remediation
Upgrade to PRTG Network Monitor version 18.2.40.1683 or later and ensure the /public directory is properly secured.
