gsd-2020-25613
Vulnerability from gsd
Modified
2020-09-29 00:00
Details
WEBrick was too tolerant against an invalid Transfer-Encoding header. This may lead to inconsistent interpretation between WEBrick and some HTTP proxy servers, which may allow the attacker to "smuggle" a request. See CWE-444 in detail.
