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. La función WEBrick::HTTPAuth::DigestAuth en Ruby versiones hasta la versión 2.4.7, versiones 2.5.x hasta 2.5.6 y versiones 2.6.x hasta 2.6.4, tiene una expresión regular de denegación de servicio causada mediante looping/backtracking.

CVSS: 5.3EPSS: 1%CPEs: 5EXPL: 0CVE-2019-16254 – ruby: HTTP response splitting in WEBrick
https://notcve.org/view.php?id=CVE-2019-16254
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. Ruby versiones hasta 2.4.7, versiones 2.5.x hasta 2.5.6 y versiones 2.6.x hasta 2.6.4, permite HTTP Response Splitting. Si un programa que utiliza WEBrick inserta información no segura en el encabezado de respuesta, un atacante puede explotarlo para insertar un carácter newline para dividir un encabezado e inyectar contenido malicioso para engañar a los clientes. • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00041.html https://hackerone.com/reports/331984 https://lists.debian.org/debian-lts-announce/2019/11/msg00025.html https://lists.debian.org/debian-lts-announce/2019/12/msg00009.html https://lists.debian.org/debian-lts-announce/2020/08/msg00027.html https://lists.debian.org/debian-lts-announce/2023/04/msg00033.html https://seclists.org/bugtraq/2019/Dec/31 https://seclists.org/bugtraq/2019/Dec/32 https://security • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') CWE-113: Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Request/Response Splitting') •
