CVE-2019-18277 (GCVE-0-2019-18277)

Vulnerability from cvelistv5 – Published: 2019-10-23 13:07 – Updated: 2024-08-05 01:47

Summary

A flaw was found in HAProxy before 2.0.6. In legacy mode, messages featuring a transfer-encoding header missing the "chunked" value were not being correctly rejected. The impact was limited but if combined with the "http-reuse always" setting, it could be used to help construct an HTTP request smuggling attack against a vulnerable component employing a lenient parser that would ignore the content-length header as soon as it saw a transfer-encoding one (even if not entirely valid according to the specification).

Severity
