https://notcve.org/view.php?id=CVE-2022-30122
A possible denial of service vulnerability exists in Rack <2.0.9.1, <2.1.4.1 and <2.2.3.1 in the multipart parsing component of Rack. Existe una posible vulnerabilidad de Denegación de Servicio (DoS) en Rack <2.0.9.1, <2.1.4.1 y <2.2.3.1 en el componente de análisis multiparte de Rack. A denial of service flaw was found in ruby-rack. An attacker crafting multipart POST requests can cause Rack's multipart parser to take much longer than expected, leading to a denial of service. • https://discuss.rubyonrails.org/t/cve-2022-30122-denial-of-service-vulnerability-in-rack-multipart-parsing/80729 https://security.gentoo.org/glsa/202310-18 https://security.netapp.com/advisory/ntap-20231208-0012 https://www.debian.org/security/2023/dsa-5530 https://access.redhat.com/security/cve/CVE-2022-30122 https://bugzilla.redhat.com/show_bug.cgi?id=2099519 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling CWE-1333: Inefficient Regular Expression Complexity •

https://notcve.org/view.php?id=CVE-2020-8161
A directory traversal vulnerability exists in rack < 2.2.0 that allows an attacker perform directory traversal vulnerability in the Rack::Directory app that is bundled with Rack which could result in information disclosure. Se presenta una vulnerabilidad de salto de directorio en rack versiones anteriores a 2.2.0, que permite a un atacante realizar una vulnerabilidad de salto de directorio en la aplicación Rack::Directory que esta incorporada con Rack, lo que podría resultar en una divulgación de información A directory traversal vulnerability was found in the Rack::Directory app that is bundled with Rack. If certain directories exist in a director managed by the Rack::Directory, this flaw allows an attacker to read the contents of files on the server outside of the root specified in the Rack::Directory initializer. The highest threat from this vulnerability is to confidentiality. • https://groups.google.com/g/rubyonrails-security/c/IOO1vNZTzPA https://hackerone.com/reports/434404 https://lists.debian.org/debian-lts-announce/2020/07/msg00006.html https://lists.debian.org/debian-lts-announce/2023/01/msg00038.html https://usn.ubuntu.com/4561-1 https://access.redhat.com/security/cve/CVE-2020-8161 https://bugzilla.redhat.com/show_bug.cgi?id=1838281 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-548: Exposure of Information Through Directory Listing •

https://notcve.org/view.php?id=CVE-2020-8184
A reliance on cookies without validation/integrity check security vulnerability exists in rack < 2.2.3, rack < 2.1.4 that makes it is possible for an attacker to forge a secure or host-only cookie prefix. Se presenta una dependencia de las cookies sin vulnerabilidad de seguridad de control de validación e integridad en rack versiones anteriores a 2.2.3, rack versiones anteriores a 2.1.4, que hace posible a un atacante forjar un prefijo de cookie seguro o solo de host A flaw was found in rubygem-rack. An attacker may be able to trick a vulnerable application into processing an insecure (non-SSL) or cross-origin request if they can gain the ability to write arbitrary cookies that are sent to the application.

CVSS: 6.3EPSS: 0%CPEs: 4EXPL: 0CVE-2019-16782 – Possible Information Leak / Session Hijack Vulnerability in Rack
https://notcve.org/view.php?id=CVE-2019-16782
There's a possible information leak / session hijack vulnerability in Rack (RubyGem rack). This vulnerability is patched in versions 1.6.12 and 2.0.8. Attackers may be able to find and hijack sessions by using timing attacks targeting the session id. Session ids are usually stored and indexed in a database that uses some kind of scheme for speeding up lookups of that session id. By carefully measuring the amount of time it takes to look up a session, an attacker may be able to find a valid session id and hijack the session. • http://lists.opensuse.org/opensuse-security-announce/2020-02/msg00016.html http://www.openwall.com/lists/oss-security/2019/12/18/2 http://www.openwall.com/lists/oss-security/2019/12/18/3 http://www.openwall.com/lists/oss-security/2019/12/19/3 http://www.openwall.com/lists/oss-security/2020/04/08/1 http://www.openwall.com/lists/oss-security/2020/04/09/2 https://github.com/rack/rack/commit/7fecaee81f59926b6e1913511c90650e76673b38 https://github.com/rack/rack/securit • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-203: Observable Discrepancy CWE-208: Observable Timing Discrepancy •
