Apache Linkis Authentication Bypass vulnerability

Critical severity GitHub Reviewed Published Jul 6, 2023 to the GitHub Advisory Database • Updated Oct 18, 2024

Package

maven org.apache.linkis:linkis (Maven)

Affected versions

< 1.3.2

Patched versions

1.3.2

Description

In Apache Linkis <=1.3.1, due to the default token generated by Linkis Gateway deployment being too simple, it is easy for attackers to obtain the default token for the attack. Generation rules should add random values.

We recommend users upgrade the version of Linkis to version 1.3.2 And modify the default token value. You can refer to Token authorization.

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.
