CVE-2024-40324Public exploitNetwork attack vector

HTTP response splitting via unsanitized CRLF input

Published Jul 25, 2024 · Updated Aug 2, 2024

CRLF injection in HTTP headers in Datex Software e-staff 5.1 allows remote attackers to split responses through crafted input fields. The application places unneutralized carriage-return and line-feed characters from an input field into HTTP headers, creating attacker-controlled header lines. The published demonstration does not identify the affected field or authentication gate; the bounded result is HTTP-header manipulation.
