Critical severity GitHub Reviewed Published Feb 2, 2024 in line/centraldogma • Updated Apr 25, 2024

Package

maven com.linecorp.centraldogma:centraldogma-server (Maven)

Affected versions

< 0.64.1

Patched versions

0.64.1

Description

Vulnerability Overview

A vulnerability has been identified in Central Dogma versions prior to 0.64.1, allowing for the leakage of user sessions and subsequent authentication bypass. The issue stems from a Cross-Site Scripting (XSS) attack vector that targets the RelayState of Security Assertion Markup Language (SAML).

Impact

Successful exploitation of this vulnerability enables malicious actors to leak user sessions, leading to the compromise of authentication mechanisms. This, in turn, can facilitate unauthorized access to sensitive resources.

Patches

This vulnerability is addressed and resolved in Central Dogma version 0.64.1 Users are strongly encouraged to upgrade to this version or later to mitigate the risk associated with the authentication bypass.

Workarounds

No viable workarounds are currently available for this vulnerability. It is recommended to apply the provided patch promptly.

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.
