SCA: security update for github.com/crewjam/saml (GHSA-267v-3v32-g6q5)

medium Tenable Self-Hosted Container Security Plugin ID 408727

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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-2023-45683)
