CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 0CVE-2024-24814 – Denial of service when manipulating mod_auth_openidc_session_chunks cookie in mod_auth_openidc
https://notcve.org/view.php?id=CVE-2024-24814
mod_auth_openidc is an OpenID Certified™ authentication and authorization module for the Apache 2.x HTTP server that implements the OpenID Connect Relying Party functionality. In affected versions missing input validation on mod_auth_openidc_session_chunks cookie value makes the server vulnerable to a denial of service (DoS) attack. An internal security audit has been conducted and the reviewers found that if they manipulated the value of the mod_auth_openidc_session_chunks cookie to a very large integer, like 99999999, the server struggles with the request for a long time and finally gets back with a 500 error. Making a few requests of this kind caused our server to become unresponsive. Attackers can craft requests that would make the server work very hard (and possibly become unresponsive) and/or crash with minimal effort. • https://github.com/OpenIDC/mod_auth_openidc/commit/4022c12f314bd89d127d1be008b1a80a08e1203d https://github.com/OpenIDC/mod_auth_openidc/security/advisories/GHSA-hxr6-w4gc-7vvv https://lists.debian.org/debian-lts-announce/2024/03/msg00004.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/T7DKVEVREYAI4F46CQAVOTPL75WLOZOE https://access.redhat.com/security/cve/CVE-2024-24814 https://bugzilla.redhat.com/show_bug.cgi?id=2264092 • CWE-400: Uncontrolled Resource Consumption •
CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 0CVE-2023-28625 – mod_auth_openidc core dump when OIDCStripCookies is set and an empty Cookie header is supplied
https://notcve.org/view.php?id=CVE-2023-28625
mod_auth_openidc is an authentication and authorization module for the Apache 2.x HTTP server that implements the OpenID Connect Relying Party functionality. In versions 2.0.0 through 2.4.13.1, when `OIDCStripCookies` is set and a crafted cookie supplied, a NULL pointer dereference would occur, resulting in a segmentation fault. This could be used in a Denial-of-Service attack and thus presents an availability risk. Version 2.4.13.2 contains a patch for this issue. As a workaround, avoid using `OIDCStripCookies`. • https://github.com/OpenIDC/mod_auth_openidc/blame/3f11976dab56af0a46a7dddb7a275cc16d6eb726/src/mod_auth_openidc.c#L178-L179 https://github.com/OpenIDC/mod_auth_openidc/commit/c0e1edac3c4c19988ccdc7713d7aebfce6ff916a https://github.com/OpenIDC/mod_auth_openidc/releases/tag/v2.4.13.2 https://github.com/OpenIDC/mod_auth_openidc/security/advisories/GHSA-f5xw-rvfr-24qr https://lists.debian.org/debian-lts-announce/2023/04/msg00034.html https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/ • CWE-476: NULL Pointer Dereference •
CVSS: 6.1EPSS: 0%CPEs: 2EXPL: 0CVE-2022-23527 – Open Redirect in oidc_validate_redirect_url()
https://notcve.org/view.php?id=CVE-2022-23527
mod_auth_openidc is an OpenID Certified™ authentication and authorization module for the Apache 2.x HTTP server. Versions prior to 2.4.12.2 are vulnerable to Open Redirect. When providing a logout parameter to the redirect URI, the existing code in oidc_validate_redirect_url() does not properly check for URLs that start with /\t, leading to an open redirect. This issue has been patched in version 2.4.12.2. Users unable to upgrade can mitigate the issue by configuring mod_auth_openidc to only allow redirection when the destination matches a given regular expression with OIDCRedirectURLsAllowed. • https://github.com/zmartzone/mod_auth_openidc/blob/v2.4.12.1/auth_openidc.conf#L975-L984 https://github.com/zmartzone/mod_auth_openidc/security/advisories/GHSA-q6f2-285m-gr53 https://lists.debian.org/debian-lts-announce/2023/07/msg00020.html https://access.redhat.com/security/cve/CVE-2022-23527 https://bugzilla.redhat.com/show_bug.cgi?id=2153655 • CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •

https://notcve.org/view.php?id=CVE-2021-39191
mod_auth_openidc is an authentication/authorization module for the Apache 2.x HTTP server that functions as an OpenID Connect Relying Party, authenticating users against an OpenID Connect Provider. In versions prior to 2.4.9.4, the 3rd-party init SSO functionality of mod_auth_openidc was reported to be vulnerable to an open redirect attack by supplying a crafted URL in the `target_link_uri` parameter. A patch in version 2.4.9.4 made it so that the `OIDCRedirectURLsAllowed` setting must be applied to the `target_link_uri` parameter. There are no known workarounds aside from upgrading to a patched version. mod_auth_openidc es un módulo de autenticación/autorización para el servidor HTTP Apache versión 2.x, que funciona como OpenID Connect Relying Party, autenticando a usuarios contra un proveedor de OpenID Connect. En las versiones anteriores a 2.4.9.4, la funcionalidad de SSO init de terceros de mod_auth_openidc era vulnerable a un ataque de redirección abierta mediante el suministro de una URL diseñada en el parámetro "target_link_uri". • https://github.com/zmartzone/mod_auth_openidc/commit/03e6bfb446f4e3f27c003d30d6a433e5dd8e2b3d https://github.com/zmartzone/mod_auth_openidc/issues/672 https://github.com/zmartzone/mod_auth_openidc/releases/tag/v2.4.9.4 https://github.com/zmartzone/mod_auth_openidc/security/advisories/GHSA-2pgf-8h6h-gqg2 https://lists.debian.org/debian-lts-announce/2023/07/msg00020.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/32RGPW5LZDLDTB7MKZIGAHPSLFOUNWR5 https://lists.fedorap • CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •
CVSS: 5.9EPSS: 0%CPEs: 4EXPL: 0CVE-2021-32791 – Hardcoded static IV and AAD with a reused key in AES GCM encryption in mod_auth_openidc
https://notcve.org/view.php?id=CVE-2021-32791
mod_auth_openidc is an authentication/authorization module for the Apache 2.x HTTP server that functions as an OpenID Connect Relying Party, authenticating users against an OpenID Connect Provider. In mod_auth_openidc before version 2.4.9, the AES GCM encryption in mod_auth_openidc uses a static IV and AAD. It is important to fix because this creates a static nonce and since aes-gcm is a stream cipher, this can lead to known cryptographic issues, since the same key is being reused. From 2.4.9 onwards this has been patched to use dynamic values through usage of cjose AES encryption routines. mod_auth_openidc es un módulo de autenticación/autorización para el servidor HTTP Apache versión 2.x que funciona como OpenID Connect Relying Party, autenticando a usuarios contra un OpenID Connect Provider.
