Concourse (7.x.y prior to 7.8.3 and 6.x.y prior to 6.7.9) contains an authorization bypass issue. A Concourse user can send a request with body including :team_name=team2 to bypass team scope check to gain access to certain resources belong to any other team.

Concourse, versions prior to 6.3.1 and 6.4.1, in installations

CVE-2020-5415 10 - Critical - August 12, 2020

Concourse, versions prior to 6.3.1 and 6.4.1, in installations which use the GitLab auth connector, is vulnerable to identity spoofing by way of configuring a GitLab account with the same full name as another user who is granted access to a Concourse team. GitLab groups do not have this vulnerability, so GitLab users may be moved into groups which are then configured in the Concourse team.

Authentication Bypass by Spoofing

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

CVE-2020-5409 6.1 - Medium - May 14, 2020

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.)

Pivotal Concourse after 2018-03-05 might allow remote attackers to have an unspecified impact, if a customer obtained the Concourse software from a DNS domain

CVE-2018-1227 7.5 - High - March 13, 2018

Pivotal Concourse after 2018-03-05 might allow remote attackers to have an unspecified impact, if a customer obtained the Concourse software from a DNS domain that is no longer controlled by Pivotal. The original domain for the Concourse CI (concourse-dot-ci) open source project has been registered by an unknown actor, and is therefore no longer the official website for Concourse CI. The new official domain is concourse-ci.org. At approximately 4 am EDT on March 7, 2018 the Concourse OSS team began receiving reports that the Concourse domain was not responding. The Concourse OSS team discovered, upon investigation with both the original and the new domain registrars, that the originating domain registrar had made the domain available for purchase. This was done despite the domain being renewed by the Concourse OSS team through August 2018. For a customer to be affected, they would have needed to access a download from a "concourse-dot-ci" domain web site after March 6, 2018 18:00:00 EST. Accessing that domain is NOT recommended by Pivotal. Anyone who had been using that domain should immediately begin using the concourse-ci.org domain instead. Customers can also safely access Concourse software from the traditionally available locations on the Pivotal Network or GitHub.
