Description

Impact

The Connection handler in Hazelcast and Hazelcast Jet allows an unauthenticated, remote attacker to access and manipulate data in the cluster with another authenticated connection's identity.
The affected Hazelcast versions are through 3.12.12, 4.0.6, 4.1.9, 4.2.5, 5.0.3, and 5.1.2.
The affected Hazelcast Jet versions are through 4.5.3.

Patches

Hazelcast Jet (and Enterprise) 4.5.4.
Hazelcast IMDG (and Enterprise)3.12.13
Hazelcast IMDG (and Enterprise) 4.1.10
Hazelcast IMDG (and Enterprise) 4.2.6
Hazelcast Platform (and Enterprise) 5.1.3

Workarounds

There is no known workaround, but setups with TLS and mutual authentication enabled significantly lowers the exploitation risk.

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.
