Encryption Flaw in Jenkins by CloudBees Non-ideal AES ECB Mode

CVE-2017-2598

What is CVE-2017-2598?

Jenkins prior to versions 2.44 and 2.32.2 uses the AES block cipher in ECB mode without an initialization vector (IV), leading to potential exposure of sensitive encrypted data. This design flaw compromises the confidentiality of stored secrets, which could be at risk of unauthorized access and exploitation. It is crucial for users to promptly update to the latest versions to mitigate these risks and secure their Jenkins environments.
