CVSS: 8.0EPSS: 0%CPEs: 4EXPL: 0CVE-2022-39369 – Service Hostname Discovery Exploitation in phpCAS
https://notcve.org/view.php?id=CVE-2022-39369
phpCAS is an authentication library that allows PHP applications to easily authenticate users via a Central Authentication Service (CAS) server. The phpCAS library uses HTTP headers to determine the service URL used to validate tickets. This allows an attacker to control the host header and use a valid ticket granted for any authorized service in the same SSO realm (CAS server) to authenticate to the service protected by phpCAS. Depending on the settings of the CAS server service registry in worst case this may be any other service URL (if the allowed URLs are configured to "^(https)://.*") or may be strictly limited to known and authorized services in the same SSO federation if proper URL service validation is applied. This vulnerability may allow an attacker to gain access to a victim's account on a vulnerable CASified service without victim's knowledge, when the victim visits attacker's website while being logged in to the same CAS server. phpCAS 1.6.0 is a major version upgrade that starts enforcing service URL discovery validation, because there is unfortunately no 100% safe default config to use in PHP. • https://github.com/apereo/phpCAS/security/advisories/GHSA-8q72-6qq8-xv64 https://lists.debian.org/debian-lts-announce/2023/07/msg00007.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/2XL7SMW6ESSP2Y6HHRYWW2MMCZSI4LBZ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/RUA2JM6YT3ZXSZLBJVRA32AXYM3GJMO3 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/VJZGTWJ5ZXUUT47EHARNOUUNTH6SYDSE • CWE-99: Improper Control of Resource Identifiers ('Resource Injection') CWE-1287: Improper Validation of Specified Type of Input •
