CVE-2018-15798

Name of the Vulnerable Software and Affected Versions Pivotal Concourse Release versions 4.x prior to 4.2.2

Description The login flow in Pivotal Concourse Release allows redirects to untrusted websites. 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.

Recommendations For versions 4.x prior to 4.2.2, update to version 4.2.2 or later to resolve the issue. As a temporary workaround, consider restricting the use of oAuth redirect links to trusted websites until a patch is applied. Avoid using the oAuth redirect link with untrusted websites to minimize the risk of exploitation.
