CVE-2023-45683 1 Saml Project 1 Saml 2024-11-21 7.1 High
github.com/crewjam/saml is a saml library for the go language. In affected versions the package does not validate the ACS Location URI according to the SAML binding being parsed. If abused, this flaw allows attackers to register malicious Service Providers at the IdP and inject Javascript in the ACS endpoint definition, achieving Cross-Site-Scripting (XSS) in the IdP context during the redirection at the end of a SAML SSO Flow. Consequently, an attacker may perform any authenticated action as the victim once the victim’s browser loaded the SAML IdP initiated SSO link for the malicious service provider. Note: SP registration is commonly an unrestricted operation in IdPs, hence not requiring particular permissions or publicly accessible to ease the IdP interoperability. This issue is fixed in version 0.4.14. Users unable to upgrade may perform external validation of URLs provided in SAML metadata, or restrict the ability for end-users to upload arbitrary metadata.
CVE-2023-28119 1 Saml Project 1 Saml 2024-11-21 7.5 High
The crewjam/saml go library contains a partial implementation of the SAML standard in golang. Prior to version 0.4.13, the package's use of `flate.NewReader` does not limit the size of the input. The user can pass more than 1 MB of data in the HTTP request to the processing functions, which will be decompressed server-side using the Deflate algorithm. Therefore, after repeating the same request multiple times, it is possible to achieve a reliable crash since the operating system kills the process. This issue is patched in version 0.4.13.
CVE-2022-41912 2 Redhat, Saml Project 4 Acm, Ceph Storage, Openshift and 1 more 2024-11-21 9.1 Critical
The crewjam/saml go library prior to version 0.4.9 is vulnerable to an authentication bypass when processing SAML responses containing multiple Assertion elements. This issue has been corrected in version 0.4.9. There are no workarounds other than upgrading to a fixed version.
CVE-2020-27846 4 Fedoraproject, Grafana, Redhat and 1 more 7 Fedora, Grafana, Enterprise Linux and 4 more 2024-11-21 9.8 Critical
A signature verification vulnerability exists in crewjam/saml. This flaw allows an attacker to bypass SAML Authentication. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
