CVE-2020-5228 Opencast allows unauthorized public access via OAI-PMH
Opencast before 8.1 and 7.6 allows unauthorized public access to all media and metadata by default via OAI-PMH. 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...
CVE-2020-5228
CVE-2020-5228 affects Opencast versions prior to 7.6/8.1 where OAI-PMH publication was enabled by default, allowing unauthenticated public access to media and metadata. The root cause is the OAI-PMH endpoint being part of the default workflow and not protected by default. Mitigations implemented ...
CVE-2020-5222: Use of Hard-coded Credentials
Opencast before 7.6 and 8.1 enables a remember-me cookie based on a hash created from the username, password, and an additional system key. This means that an attacker getting access to a remember-me token for one server can get access to all servers which allow log-in using the same credentials...
CVE-2020-5206: Improper Authorization
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: Improper Authorization
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-2020-5230: Improper Control of Resource Identifiers
Opencast before 8.1 and 7.6 allows almost arbitrary identifiers for media packages and elements to be used. This can be problematic for operation and security since such identifiers are sometimes used for file system operations which may lead to an attacker being able to escape working directorie...
CVE-2020-5228: Missing Authorization
Opencast before 8.1 and 7.6 allows unauthorized public access to all media and metadata by default via OAI-PMH. 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...
CVE-2020-5229: Use of a Broken or Risky Cryptographic Algorithm
Opencast before 8.1 stores passwords 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 problematic especially...

Design/Logic Flaw
In Opencast 2.2.3 and older if user names overlap, the Opencast search service used for publication to the media modules and players will handle the access control incorrectly so that users only need to match part of the user name used for the access restriction. For example, a user with the role...
