Description

This security bulletin contains information about 1 vulnerability.

1) Deserialization of Untrusted Data (CVE-ID: CVE-2023-42809)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to some of the messages received from the Redis server contain Java objects that the client deserializes without further validation. A remote attacker can manage to trick clients into communicating with a malicious server to include especially crafted objects in its responses that, once deserialized by the client, force it to execute arbitrary code. This can be abused to take control of the machine the client is running in.

Remediation
