Vulnerability from github – Published: 2018-01-04 21:03 – Updated: 2023-08-18 21:00

Summary

Samlify vulnerable to Authentication Bypass by allowing tokens to be reused with different usernames

Details

Versions of samlify prior to 2.4.0-rc5 are vulnerable to Authentication Bypass. The package fails to prevent XML Signature Wrapping, allowing tokens to be reused with different usernames. A remote attacker can modify SAML content for a SAML service provider without invalidating the cryptographic signature, which may allow attackers to bypass primary authentication for the affected SAML service provider.

Recommendation

Upgrade to version 2.4.0-rc5 or later

Severity

7.5 (High)
