Revenue Collection System 1.0 SQL Injection / Remote Code Execution

Posted on 16 November 2022

Revenue Collection System version 1.0 suffers from an unauthenticated SQL injection vulnerability in step1.php that allows remote attackers to write a malicious PHP file to disk. The resulting file can then be accessed within the /rates/admin/DBbackup directory. This script will write the malicious PHP file to disk, issue a user-defined command, then retrieve the result of that command.
