CVSS: 7.5EPSS: 0%CPEs: 6EXPL: 1CVE-2020-25613 – ruby: Potential HTTP request smuggling in WEBrick
https://notcve.org/view.php?id=CVE-2020-25613
An issue was discovered in Ruby through 2.5.8, 2.6.x through 2.6.6, and 2.7.x through 2.7.1. WEBrick, a simple HTTP server bundled with Ruby, had not checked the transfer-encoding header value rigorously. An attacker may potentially exploit this issue to bypass a reverse proxy (which also has a poor header check), which may lead to an HTTP Request Smuggling attack. Se detectó un problema en Ruby versiones hasta 2.5.8, versiones 2.6.x hasta 2.6.6 y versiones 2.7.x hasta 2.7.1. WEBrick, un simple servidor HTTP integrado con Ruby, no había comprobado rigurosamente el valor del encabezado transfer-encoding. • https://github.com/metapox/CVE-2020-25613 https://github.com/ruby/webrick/commit/8946bb38b4d87549f0d99ed73c62c41933f97cc7 https://hackerone.com/reports/965267 https://lists.debian.org/debian-lts-announce/2023/04/msg00033.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PFP3E7KXXT3H3KA6CBZPUOGA5VPFARRJ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/YTZURYROG3FFED3TYCQOBV66BS4K6WOV https://security.gentoo.org/glsa/202401-27 https://sec • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •

https://notcve.org/view.php?id=CVE-2019-11879
The WEBrick gem 1.4.2 for Ruby allows directory traversal if the attacker once had local access to create a symlink to a location outside of the web root directory. NOTE: The vendor states that this is analogous to Options FollowSymlinks in the Apache HTTP Server, and therefore it is "not a problem. ** EN DISPUTA ** La WEBrick gem versión 1.4.2 para Ruby permite salto de directorio si el atacante alguna vez tuvo acceso local para crear un enlace simbólico a una ubicación fuera del directorio web root. NOTA: El proveedor declara que esto es similar a las Opciones FollowSymlinks en el Servidor HTTP de Apache, y por lo tanto "no es un problema". • https://bugs.ruby-lang.org/issues/15835 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-59: Improper Link Resolution Before File Access ('Link Following') •

https://notcve.org/view.php?id=CVE-2009-4492
WEBrick 1.3.1 in Ruby 1.8.6 through patchlevel 383, 1.8.7 through patchlevel 248, 1.8.8dev, 1.9.1 through patchlevel 376, and 1.9.2dev writes data to a log file without sanitizing non-printable characters, which might allow remote attackers to modify a window's title, or possibly execute arbitrary commands or overwrite files, via an HTTP request containing an escape sequence for a terminal emulator. WEBrick v1.3.1 en Ruby v1.8.6 del patchlevel 383, v1.8.7 al patchlevel 248, v1.8.8dev, 1.9.1 al patchlevel 376, y v1.9.2dev ,escribe datos en un archivo de los sin depurar los caracteres no escribibles, lo que podría permitir a atacantes remotos modificar la ventana de título, o posiblemente ejecutar comandos de su elección o sobrescribir archivos, a través de una petición HTTP que contiene una secuencia de escape para el emulador de terminal. Nginx, Varnish, Cherokee, thttpd, mini-httpd, WEBrick, Orion, AOLserver, Yaws and Boa are subject to log escape sequence injection vulnerabilities. • https://www.exploit-db.com/exploits/33489 http://secunia.com/advisories/37949 http://securitytracker.com/id?1023429 http://www.redhat.com/support/errata/RHSA-2011-0908.html http://www.redhat.com/support/errata/RHSA-2011-0909.html http://www.ruby-lang.org/en/news/2010/01/10/webrick-escape-sequence-injection http://www.securityfocus.com/archive/1/508830/100/0/threaded http://www.securityfocus.com/bid/37710 http://www.ush.it/team/ush/hack_httpd_escape/adv.txt http: •

Directory traversal vulnerability in WEBrick in Ruby 1.8 before 1.8.5-p115 and 1.8.6-p114, and 1.9 through 1.9.0-1, when running on systems that support backslash (\) path separators or case-insensitive file names, allows remote attackers to access arbitrary files via (1) "..%5c" (encoded backslash) sequences or (2) filenames that match patterns in the :NondisclosureName option. Una vulnerabilidad de salto de directorio en WEBrick en Ruby versiones 1.8 anteriores a 1.8.5-p115 y 1.8.6-p114, y versiones 1.9 hasta 1.9.0-1, cuando se ejecuta en sistemas que admiten separadores de ruta de barra invertida (\) o nombres de archivo sin distinción entre mayúsculas y minúsculas, permite a atacantes remotos acceder a archivos arbitrarios por medio de secuencias o (1) "..%5c" (barra invertida codificada) o (2) nombres de archivo que coinciden con los patrones de la opción :NondisclosureName. • https://www.exploit-db.com/exploits/5215 http://lists.apple.com/archives/security-announce/2008//Jun/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2008-08/msg00006.html http://secunia.com/advisories/29232 http://secunia.com/advisories/29357 http://secunia.com/advisories/29536 http://secunia.com/advisories/30802 http://secunia.com/advisories/31687 http://secunia.com/advisories/32371 http://support.apple.com/kb/HT2163 http://wiki.rpath.com/Advisories:rPSA&# • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •
