Summary
Moodle SSRF Vulnerability
Details

The edit_blog.php script allows a registered user to add external RSS feed resources. It was identified that this feature could be abused to be used as a SSRF attack vector by adding a malicious URL/TCP PORT in order to target internal network or an internet hosted server, bypassing firewall rules, IP filtering and more.

This kind of vulnerability is then called “blind” because of no response available on Moodle web site, enforcing attacker to exploit it using a “time based” approach.

Severity ?
7.5 (High)
CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H
