CVSS: 7.1EPSS: 0%CPEs: 1EXPL: 0CVE-2023-45683 – Cross site scripting via missing binding syntax validation In ACS location in github.com/crewjam/saml
https://notcve.org/view.php?id=CVE-2023-45683
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. • https://github.com/crewjam/saml/commit/b07b16cf83c4171d16da4d85608cb827f183cd79 https://github.com/crewjam/saml/security/advisories/GHSA-267v-3v32-g6q5 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
CVSS: 5.3EPSS: 0%CPEs: 1EXPL: 0CVE-2023-40178 – @node-saml/node-saml's validatePostRequestAsync does not include checkTimestampsValidityError
https://notcve.org/view.php?id=CVE-2023-40178
Node-SAML is a SAML library not dependent on any frameworks that runs in Node. The lack of checking of current timestamp allows a LogoutRequest XML to be reused multiple times even when the current time is past the NotOnOrAfter. This could impact the user where they would be logged out from an expired LogoutRequest. In bigger contexts, if LogoutRequests are sent out in mass to different SPs, this could impact many users on a large scale. This issue was patched in version 4.0.5. • https://github.com/node-saml/node-saml/commit/045e3b9c54211fdb95f96edf363679845b195cec https://github.com/node-saml/node-saml/releases/tag/v4.0.5 https://github.com/node-saml/node-saml/security/advisories/GHSA-vx8m-6fhw-pccw • CWE-347: Improper Verification of Cryptographic Signature CWE-613: Insufficient Session Expiration •
CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 0CVE-2023-28119 – crewjam/saml vulnerable to Denial Of Service Via Deflate Decompression Bomb
https://notcve.org/view.php?id=CVE-2023-28119
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. • https://github.com/crewjam/saml/commit/8e9236867d176ad6338c870a84e2039aef8a5021 https://github.com/crewjam/saml/security/advisories/GHSA-5mqj-xc49-246p • CWE-770: Allocation of Resources Without Limits or Throttling •

https://notcve.org/view.php?id=CVE-2022-41912
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. La librería Crewjam/saml go anterior a la versión 0.4.9 es vulnerable a una omisión de autenticación al procesar respuestas SAML que contienen múltiples elementos de afirmación.
