Description

A vulnerability of plugin openid-connect in Apache APISIX.

This vulnerability will only have an impact if all of the following conditions are met:

  1. Use the openid-connect plugin with introspection mode
  2. The auth service connected to openid-connect provides services to multiple issuers
  3. Multiple issuers share the same private key and relies only on the issuer being different

If affected by this vulnerability, it would allow an attacker with a valid account on one of the issuers to log into the other issuer.

This issue affects Apache APISIX: until 3.12.0.

Users are recommended to upgrade to version 3.12.0 or higher.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.

Weaknesses

Authentication Bypass by Assumed-Immutable Data

The authentication scheme or implementation uses key data elements that are assumed to be immutable, but can be controlled or modified by the attacker. Learn more on MITRE.
