CVE-2020-2114Network attack vector

Secret-key exposure via plaintext configuration transmission

Published Feb 12, 2020 · Updated Aug 4, 2024

Cleartext transmission in Jenkins S3 publisher Plugin 0.11.4 and earlier allows context-dependent attackers to read a secret key. The global configuration form inserts the stored S3 secret key into its response without preserving the encryption used for storage. Exposure requires the form data to become visible to a browser extension, a cross-site scripting payload, or a similar observer, and is limited to credential disclosure.
