HTTP Request Smuggling

Overview webrick is a HTTP server toolkit that can be configured as an HTTPS server, a proxy server, and a virtual-host server. Affected versions of this package are vulnerable to HTTP Request Smuggling. It was too tolerant against an invalid Transfer-Encoding header. This may lead to inconsisten...

Potential HTTP Request Smuggling Vulnerability in WEBrick

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...

Ruby through 2.4.7 2.5.x through 2.5.6 and 2.6.x through 2.6.4 allows HTTP Response Splitting. If a program using WEBrick inserts untrusted input into the response header an attacker can exploit it to insert a newline character to split a header and inject malicious content to deceive clients. NOTE: this issue exists because of an incomplete fix for CVE-2017-17742 which addressed the CRLF vector but did not address an isolated CR or an isolated LF.

WEBrick::HTTPAuth::DigestAuth in Ruby through 2.4.7 2.5.x through 2.5.6 and 2.6.x through 2.6.4 has a regular expression Denial of Service cause by looping/backtracking. A victim must expose a WEBrick server that uses DigestAuth to the Internet or a untrusted network.
