CWE-499

Serializable Class Containing Sensitive Data

Category: VariantCVE: 2

Description

The code contains a class with sensitive data, but the class does not explicitly deny serialization. The data can be accessed by serializing the class through another class.

Extended Description

Serializable classes are effectively open classes since data cannot be hidden in them. Classes that do not explicitly deny serialization can be serialized by any other class, which can then in turn use the data stored inside it.

MEDIUM

CVE-2022-39309

GoCD is a continuous delivery server. GoCD helps you automate and streamline the build-test-release cycle for continuous delivery of your product. GoCD versions prior to 21.1.0 leak the symmetric key used to encrypt/decrypt any secure variables/secrets in GoCD configuration to authenticated agents. A malicious/compromised agent may then expose that key from memory, and potentially allow an attacker the ability to decrypt secrets intended for other agents/environments if they also are able to obtain access to encrypted configuration values from the GoCD server. This issue is fixed in GoCD version 21.1.0. There are currently no known workarounds.
