CVE-2016-15032Network attack vector

Cross-site scripting via unescaped address output

Published Jun 1, 2023 · Updated Aug 6, 2024

Cross-site scripting in mback2k http:BL Blocking 1.1.0 through 1.1.7 allows remote attackers to inject script into a TYPO3 block page. The stopOutput function inserts REMOTE_ADDR and its reverse-host lookup into the REQUEST_IP placeholder without HTML encoding. Exploitation requires a browser to render a generated blocking page containing attacker-controlled address or reverse-host data.
