CVSS: 6.5EPSS: 0%CPEs: 1EXPL: 0CVE-2021-41267 – Webcache Poisoning in Symfony
https://notcve.org/view.php?id=CVE-2021-41267
Symfony/Http-Kernel is the HTTP kernel component for Symfony, a PHP framework for web and console applications and a set of reusable PHP components. Headers that are not part of the "trusted_headers" allowed list are ignored and protect users from "Cache poisoning" attacks. In Symfony 5.2, maintainers added support for the `X-Forwarded-Prefix` headers, but this header was accessible in SubRequest, even if it was not part of the "trusted_headers" allowed list. An attacker could leverage this opportunity to forge requests containing a `X-Forwarded-Prefix` header, leading to a web cache poisoning issue. Versions 5.3.12 and later have a patch to ensure that the `X-Forwarded-Prefix` header is not forwarded to subrequests when it is not trusted. • https://github.com/symfony/symfony/commit/95dcf51682029e89450aee86267e3d553aa7c487 https://github.com/symfony/symfony/pull/44243 https://github.com/symfony/symfony/releases/tag/v5.3.12 https://github.com/symfony/symfony/security/advisories/GHSA-q3j3-w37x-hq2q • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
CVSS: 8.8EPSS: 0%CPEs: 1EXPL: 0CVE-2021-41268 – Cookie persistence in Symfony
https://notcve.org/view.php?id=CVE-2021-41268
Symfony/SecurityBundle is the security system for Symfony, a PHP framework for web and console applications and a set of reusable PHP components. Since the rework of the Remember me cookie in version 5.3.0, the cookie is not invalidated when the user changes their password. Attackers can therefore maintain their access to the account even if the password is changed as long as they have had the chance to login once and get a valid remember me cookie. Starting with version 5.3.12, Symfony makes the password part of the signature by default. In that way, when the password changes, then the cookie is not valid anymore. • https://github.com/symfony/symfony/commit/36a808b857cd3240244f4b224452fb1e70dc6dfc https://github.com/symfony/symfony/pull/44243 https://github.com/symfony/symfony/releases/tag/v5.3.12 https://github.com/symfony/symfony/security/advisories/GHSA-qw36-p97w-vcqr • CWE-384: Session Fixation •
CVSS: 8.8EPSS: 0%CPEs: 1EXPL: 0CVE-2021-32693 – Authentication granted with multiple firewalls
https://notcve.org/view.php?id=CVE-2021-32693
Symfony is a PHP framework for web and console applications and a set of reusable PHP components. A vulnerability related to firewall authentication is in Symfony starting with version 5.3.0 and prior to 5.3.2. When an application defines multiple firewalls, the token authenticated by one of the firewalls was available for all other firewalls. This could be abused when the application defines different providers for each part of the application, in such a situation, a user authenticated on a part of the application could be considered authenticated on the rest of the application. Starting in version 5.3.2, a patch ensures that the authenticated token is only available for the firewall that generates it. • https://github.com/symfony/security-http/commit/6bf4c31219773a558b019ee12e54572174ff8129 https://github.com/symfony/symfony/commit/3084764ad82f29dbb025df19978b9cbc3ab34728 https://github.com/symfony/symfony/security/advisories/GHSA-rfcf-m67m-jcrq https://symfony.com/blog/cve-2021-32693-authentication-granted-to-all-firewalls-instead-of-just-one • CWE-287: Improper Authentication •
CVSS: 5.3EPSS: 0%CPEs: 5EXPL: 0CVE-2021-21424 – Prevent user enumeration using Guard or the new Authenticator-based Security
https://notcve.org/view.php?id=CVE-2021-21424
Symfony is a PHP framework for web and console applications and a set of reusable PHP components. The ability to enumerate users was possible without relevant permissions due to different handling depending on whether the user existed or not when attempting to use the switch users functionality. We now ensure that 403s are returned whether the user exists or not if a user cannot switch to a user or if the user does not exist. The patch for this issue is available for branch 3.4. Symfony es un framework PHP para aplicaciones web y de consola y un conjunto de componentes PHP reutilizables. • https://github.com/symfony/symfony/commit/2a581d22cc621b33d5464ed65c4bc2057f72f011 https://github.com/symfony/symfony/security/advisories/GHSA-5pv8-ppvj-4h68 https://lists.debian.org/debian-lts-announce/2023/07/msg00014.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/KENRNLB3FYXYGDWRBH2PDBOZZKOD7VY4 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/RH7TMM5CHQYBFFGXWRPJDPB3SKCZXI2M https://lists.fedoraproject.org/archives/list/package-announce%40lists.fe • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-203: Observable Discrepancy •
CVSS: 8.8EPSS: 0%CPEs: 6EXPL: 0CVE-2020-15094 – RCE in Symfony
https://notcve.org/view.php?id=CVE-2020-15094
In Symfony before versions 4.4.13 and 5.1.5, the CachingHttpClient class from the HttpClient Symfony component relies on the HttpCache class to handle requests. HttpCache uses internal headers like X-Body-Eval and X-Body-File to control the restoration of cached responses. The class was initially written with surrogate caching and ESI support in mind (all HTTP calls come from a trusted backend in that scenario). But when used by CachingHttpClient and if an attacker can control the response for a request being made by the CachingHttpClient, remote code execution is possible. This has been fixed in versions 4.4.13 and 5.1.5. • https://github.com/symfony/symfony/commit/d9910e0b33a2e0f993abff41c6fbc86951b66d78 https://github.com/symfony/symfony/security/advisories/GHSA-754h-5r27-7x3r https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/HNGUWOEETOFVH4PN3I3YO4QZHQ4AUKF3 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VAQJXAKWPMWB7OL6QPG2ZSEQZYYPU5RC https://packagist.org/packages/symfony/http-kernel https://packagist.org/packages/symfony/symfony • CWE-212: Improper Removal of Sensitive Information Before Storage or Transfer •
