CVE-2020-2091Network attack vector

Authenticated SSRF via unchecked form validation

Published Jan 15, 2020 · Updated Aug 4, 2024

SSRF in Jenkins Amazon EC2 Plugin 1.47 and earlier allows remote authenticated users to initiate outbound AWS-region connections. Its form-validation methods accept an attacker-specified URL and credentials ID, then connect without enforcing Overall/Administer permission. Overall/Read access and a credentials ID obtained elsewhere are required; unauthorized outbound connection is confirmed, but credential capture is unconfirmed.
