Summary
The remote host is missing an update for the Huawei EulerOS 'haproxy' package(s) announced via the EulerOS-SA-2020-1105 advisory.
Insight
Insight
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).(CVE-2019-18277)
