iMLog < 1.307 is vulnerable to persistent cross-site scripting (XSS) via the "User Management" feature. An attacker could inject malicious javascript code on a controlled user so when an admin goes to the "User Maintenance" malicious code is executed and could lead to new admin user creations resulting in privilege escalation.

1. Login to user account
2. Go to Setup > "User Maintenance"
3. Click on "Search" and then select your UserID.
4. Change the "Last Name" input to `<img/src/onerror=prompt('XSS')>`
5. Click on "Save"
6. Refresh the page, XSS will be triggered.
