hznuoj's Issues

Insufficient SQL filtering results in xss injection

description

The code problem occurred in OJ / admin-tools / cal_scores.php. The $ realname in the output form was obtained from the database. There was no filtering of angle brackets “<>” during registration, which caused the reorganization here. xss injection
