Kerentanan Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') pada gnome libsoup, redhat enterprise linux. Skor CVSS 3.1 6.5 (Medium) menurut NVD.

Deskripsi (NVD)

A flaw was found in libsoup, an HTTP client/server library. This HTTP Request Smuggling vulnerability arises from non-RFC-compliant parsing in the soup_filter_input_stream_read_line() logic, where libsoup accepts malformed chunk headers, such as lone line feed (LF) characters instead of the required carriage return and line feed (CRLF). A remote attacker can exploit this without authentication or user interaction by sending specially crafted chunked requests. This allows libsoup to parse and process multiple HTTP requests from a single network message, potentially leading to information disclosure.
