CVE-2025-44203: 
Linux Debian vulnerability analysis and mitigation

CVE-2025-44203 is a vulnerability discovered in HotelDruid versions 3.0.0 and 3.0.7, disclosed on June 20, 2025. The vulnerability affects the creadb.php endpoint before the 'create database' button is pressed. This security flaw allows an unauthenticated attacker to exploit verbose SQL error messages to obtain sensitive information (NVD, GitHub).

The vulnerability exists in the creadb.php endpoint of HotelDruid's installation process. By sending malformed POST requests to this endpoint before the database creation step, an attacker can exploit verbose SQL error messages to extract sensitive information including administrator username, password hash, and salt. The vulnerability is particularly exploitable when HotelDruid's access is not restricted to localhost during the debian package configuration (GitHub).

The successful exploitation of this vulnerability leads to two main impacts: 1) Disclosure of sensitive information including administrator username, password hash, and salt, which could potentially lead to password recovery through brute force attacks if the password is weak, and 2) A Denial of Service (DoS) condition that prevents the administrator from logging in with their credentials, even when correct (GitHub).

The primary mitigation is to ensure that during HotelDruid debian package configuration, the option 'Restrict HotelDruid access to localhost?' is set to 'Yes'. Additionally, administrators should consider implementing a Web Application Firewall (WAF) to help protect against unauthorized access to the installation endpoints (GitHub).
