CVE-2020-5409

Pivotal Concourse, most versions prior to 6.0.0, allows redirects to untrusted websites in its login flow.

MEDIUM 6.1EPSS 0.91%

Does this matter?

Lower severity and a low EPSS score (0.91%). Track it; it rarely justifies an emergency change on its own.

Description

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.)
