Harded Coded Remember-Me Cookie

Opencast uses a harded coded remember-me cookie. The remember-me cookie is created by hashing the username, password, and an additional system key, allowing anyone with an access to the remember-me token for one server to compromise all servers using the same credentials...

Authentication Bypass

opencast-kernel is vulnerable to authentication bypass. The vulnerability exists as media publication via OAI-PMH allows unauthenticated public access to all media and metadata by default...

Authorization Bypass

opencast-kernel is vulnerable to authorization bypass. The vulnerability exists as a user with the non-standard role, ROLECOURSEADMIN, is able to create new users using the user-utils endpoint...

Authentication Bypass

opencast-kernel is vulnerable to authentication bypass. The vulnerability exists as a fake remember-me token can be used to gain access of arbitrary users without the need to be authenticated...

Weak Encryption Standards

opencast-kernel is vulnerable to weak encryption standards. It uses a broken hashing standard, MD5, to hash sensitive information, such as passwords, for its cookies...

CVE-2020-5206

In Opencast before 7.6 and 8.1, using a remember-me cookie with an arbitrary username can cause Opencast to assume proper authentication for that user even if the remember-me cookie was incorrect given that the attacked endpoint also allows anonymous access. This way, an attacker can, for example...

CVE-2020-5231

In Opencast before 7.6 and 8.1, users with the role ROLECOURSEADMIN can use the user-utils endpoint to create new users not including the role ROLEADMIN. ROLECOURSEADMIN is a non-standard role in Opencast which is referenced neither in the documentation nor in any code except for tests but only i...

Authentication flaw

In Opencast before 7.6 and 8.1, using a remember-me cookie with an arbitrary username can cause Opencast to assume proper authentication for that user even if the remember-me cookie was incorrect given that the attacked endpoint also allows anonymous access. This way, an attacker can, for example...

Default configuration

In Opencast before 7.6 and 8.1, users with the role ROLECOURSEADMIN can use the user-utils endpoint to create new users not including the role ROLEADMIN. ROLECOURSEADMIN is a non-standard role in Opencast which is referenced neither in the documentation nor in any code except for tests but only i...

CVE-2020-5206

Opencast prior to versions 7.6 and 8.1 was vulnerable to an authentication bypass: a fake remember-me token could be accepted as a valid login for a user (even if the token was incorrect) because the attacked endpoint allowed anonymous access. This could let an attacker impersonate a user, includ...

CVE-2020-5206 Authentication Bypass For Endpoints With Anonymous Access in OpenCast

In Opencast before 7.6 and 8.1, using a remember-me cookie with an arbitrary username can cause Opencast to assume proper authentication for that user even if the remember-me cookie was incorrect given that the attacked endpoint also allows anonymous access. This way, an attacker can, for example...

GHSA-6F54-3QR9-PJGJ Unauthenticated Access Via OAI-PMH

Impact Media publication via OAI-PMH allows unauthenticated public access to all media and metadata by default. OAI-PMH is part of the default workflow and is activated by default, requiring active user intervention of users to protect media. This leads to users unknowingly handing out public...

Password Hashing: Do not use MD5

Impact User passwords are stored in the database using the rather outdated and cryptographically insecure MD5 hash algorithm. Furthermore, the hashes are salted using the username instead of a random salt, causing hashes for users with the same username and password to collide which is problemati...
