Impact Opencast 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 directories and write...

GHSA-MH8G-HPRG-8363 Hard-Coded Key Used For Remember-me Token in Opencast

Impact The security configuration in etc/security/mhdefaultorg.xml enables a remember-me cookie based on a hash created from the username, password, and an additional system key. Opencast has hard-coded this system key in the large XML file and never mentions to change this, basically ensuring th...

Users with ROLE_COURSE_ADMIN can create new users in Opencast

Impact Users with the role ROLECOURSEADMIN can use the user-utils endpoint to create new users not including the role ROLEADMIN. For example: bash Use the admin to create a new user with ROLECOURSEADMIN using the admin user. We expect this to work. % curl -i -u admin:opencast...

Impact Users with the role ROLECOURSEADMIN can use the user-utils endpoint to create new users not including the role ROLEADMIN. For example: bash Use the admin to create a new user with ROLECOURSEADMIN using the admin user. We expect this to work. % curl -i -u admin:opencast...

GHSA-VMM6-W4CF-7F3X Authentication Bypass For Endpoints With Anonymous Access in Opencast

Impact 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, fake a remember-me toke...

Authentication Bypass For Endpoints With Anonymous Access in Opencast

Impact 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, fake a remember-me toke...

CVE-2020-5231

Opencast is affected in versions before 7.6 and before 8.1 where users with the non‑standard ROLE_COURSE_ADMIN can use the user-utils endpoint to create new users (not granting ROLE_ADMIN). Root cause: a misconfiguration in security allowing creation by a course admin. Impact: authorization bypas...

CVE-2020-5231 Opencast users with ROLE_COURSE_ADMIN can create new users

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

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 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-2020-5222

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...

Code injection

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...

Default 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-2020-5230

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...
