VUL-0: CVE-2023-45683: teleport: github.com/crewjam/saml: XSS via missing Binding syntax validation
Last modified: 2024-01-24 16:37:16 UTC
Impact 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: The severity is considered “High” because the SP registration is commonly an unrestricted operation in IdPs, hence not requiring particular permissions or publicly accessible to ease the IdP interoperability. Patches This issue is fixed in 0.4.14 Workarounds Users of the package can perform external validation of URLs provided in SAML metadata, or restrict the ability for end-users to upload arbitrary metadata.

github.com/crewjam/saml is embedded in: - openSUSE:Factory/teleport (github.com/crewjam/saml v0.4.12)
I went back as far as teleport 13.3.8, which was sent to Factory beginning of September. This already had "github.com/crewjam/saml v0.4.14-0.20230420111643-34930b26d33b" in the go.mod file. So I daresay this should already be fixed in Tumbleweed. But the issue says something regarding 15.6, not sure which version is included in Leap 15.6. Kind Regards Johannes
All fixed, closing.
