CVE-2024-5737Public exploitNetwork attack vector

HTML injection via missing image content type

Published Jun 28, 2024 · Updated Aug 1, 2024

HTML injection in Nikola Vasilijevski AdmirorFrames before 5.0 allows remote attackers to inject HTML through crafted image data. The afGdStream.php script sends attacker-controlled image bytes without a Content-Type header, so PHP defaults the response to text/html. Exploitation requires a browser to load the crafted response, allowing injected markup to alter rendered page content.
