Background
Postfix Admin is a web-based management tool for Postfix mail servers, allowing administrators to manage email accounts and domains easily. It provides a user-friendly interface and various features, including user authentication and backup functionalities. However, prior to version 2.3.5, Postfix Admin was susceptible to multiple SQL injection vulnerabilities, which could be exploited by authenticated users to execute arbitrary SQL commands.
Vulnerability Detail
Multiple SQL injection vulnerabilities in Postfix Admin (aka postfixadmin) before version 2.3.5 allow remote authenticated users to execute arbitrary SQL commands. The vulnerabilities arise from improper handling of user input, specifically in the 'pw' parameter of the 'pacrypt' function when 'mysql_encrypt' is configured, and other unspecified vectors used in backup files generated by 'backup.php'. This can lead to unauthorized data access, data manipulation, and potential system compromise.
