Session Fixation in Apache CXF

High severity GitHub Reviewed Published May 13, 2022 to the GitHub Advisory Database • Updated Dec 21, 2023

Package

maven org.apache.cxf:cxf-core (Maven)

Affected versions

>= 3.1.0, <= 3.1.10
<= 3.0.12

Patched versions

3.1.11
3.0.13

Description

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.
