CVE-2020-5230

Opencast CVE-2020-5230 affects Opencast versions older than 8.1 and 7.6, where media package and element identifiers can be almost arbitrary. The identifiers are sometimes used in filesystem operations, which can allow an attacker to escape working directories and write files to unintended locati...

CVE-2020-5230 Opencast uses unsafe 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-2020-5222

Opencast prior to 7.6 and 8.1 uses a remember-me cookie whose value is derived from a hash of the username, password, and a system key. If an attacker obtains a remember-me token from one server, they can access other servers that accept the same credentials without handling credentials. The issu...

CVE-2020-5222 Hard-Coded Key Used For Remember-me Token in OpenCast

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-2020-5228

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

Opencast before 8.1 stores passwords using the rather outdated and cryptographically insecure MD5 hash algorithm.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...

CVE-2020-5229

Opencast CVE-2020-5229 concerns weak password hashing: previous releases stored passwords with MD5 salted by username, causing vulnerability where attacker with DB access could attempt password cracking. Opencast 8.1 switched to bcrypt, but legacy MD5 hashes remain until passwords are updated. Af...

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 ...
