An attacker may cause an HTTP/2 endpoint to read arbitrary amounts of header data by sending an excessive number of CONTINUATION frames. Maintaining HPACK state requires parsing and processing all HEADERS and CONTINUATION frames on a connection. When a request's headers exceed MaxHeaderBytes, no memory is allocated to store the excess headers, but they are still parsed. This permits an attacker to cause an HTTP/2 endpoint to read arbitrary amounts of header data, all associated with a request which is going to be rejected. These headers can include Huffman-encoded data which is significantly more expensive for the receiver to decode than for an attacker to send. The fix sets a limit on the amount of excess header frames we will process before closing a connection.\n\nFIRST-EPSS: 0.000450000", "creation_timestamp": "2024-04-07T22:26:02.000000Z"} 2024-04-07T22:26:02+00:00 https://vulnerability.circl.lu/sighting/c5980e3d-a9c7-45e1-b91d-f0b897cf950f/export 2026-05-28T05:17:00.541917+00:00 Automation user https://cve.circl.lu/user/automation {"uuid": "c5980e3d-a9c7-45e1-b91d-f0b897cf950f", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2023-45288", "type": "seen", "source": "https://t.me/arpsyndicate/4415", "content": "#ExploitObserverAlert\n\nCVE-2023-45288\n\nDESCRIPTION: Exploit Observer has 43 entries in 10 file formats related to CVE-2023-45288.
