This vulnerability allowed unauthenticated users to execute arbitrary SQL commands. GitHub PoCs for this often show how to extract the admin_user table, which contains the salted hashes of administrator passwords.

Merchants must understand that the risk increases over time—as hackers continue to develop new exploitation techniques and discover additional undisclosed vulnerabilities, unpatched Magento 1 installations become increasingly dangerous. The combination of automated scanners on GitHub, publicly available exploit code, and the complete absence of security updates makes running Magento 1.x after its end-of-life a severe business risk. The recommended course of action is clear: migrate to Magento 2 or an alternative supported platform immediately, and in the meantime, implement defense-in-depth security measures including WAF protection, regular malware scanning, and continuous monitoring for compromise.

Once the admin user is created, the attacker logs in and uses the Magento "Connect Manager" or template editors to upload a PHP shell. SQL Injection and PHP Object Injection

Use a Web Application Firewall (WAF): A WAF can block many of the common exploit patterns found in GitHub scripts before they reach your server.

Is your Magento 1.9.0.0 store and accepting payments?

Magento 1.9.0.0 was released in 2014. It remains a frequent target for cybercriminals. Security researchers and malicious actors actively host proof-of-concept (PoC) exploits on GitHub. Understanding these repositories is critical for securing legacy systems. Why Magento 1.9.0.0 Remains Vulnerable

Many exploits occur through outdated third-party extensions. Remove anything you are not actively using. The Ultimate Solution: Migration
