SCA: security update for CIE.AspNetCore.Authentication (GHSA-vq63-8f72-f486)

critical Tenable Cloud Security Plugin ID 420914

Description

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

 - CIE.AspNetCore.Authentication is an AspNetCore Remote Authenticator for CIE 3.0. Authentication using Spid
 and CIE is based on the SAML2 standard which provides two entities: 1. Identity Provider (IDP): the system
 that authenticates users and provides identity information (SAML affirmation) to the Service Provider, in
 essence, is responsible for the management of the credentials and identity of users; 2. Service Provider
 (SP): the system that provides a service to the user and relies on the Identity Provider to authenticate
 the user, receives SAML assertions from the IdP to grant access to resources. The library cie-aspnetcore
 refers to the second entity, the SP, and implements the validation logic of SAML assertions within SAML
 responses. In affected versions there is no guarantee that the first signature refers to the root object,
 it follows that if an attacker injects an item signed as the first element, all other signatures will not
 be verified. The only requirement is to have an XML element legitimately signed by the IdP, a condition
 that is easily met using the IdP's public metadata. An attacker could create an arbitrary SAML response
 that would be accepted by SPs using vulnerable SDKs, allowing him to impersonate any Spid and/or CIE user.
 This issue has been addressed in version 2.1.0 and all users are advised to upgrade. There are no known
 workarounds for this vulnerability. (CVE-2025-24895)
