Description
This security bulletin contains information about 1 security vulnerability.
1) Open redirect (CVE-ID: CVE-2020-5409)
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
Pivotal Concourse, most versions prior to 6.0.0, allows redirects to untrusted websites in its login flow. A remote unauthenticated attacker could convince a user to click on a link using the OAuth redirect link with an untrusted website and gain access to that user's access token in Concourse. (This issue is similar to, but distinct from, CVE-2018-15798.)
Remediation
Install update from vendor's website.
