Apache Zeppelin vulnerabilities

In Apache Zeppelin versions 0.9.0 through 0.12.0, when FileSystemNotebookRepo is configured, an authenticated attacker with rename or folder operation permissions can use traversal segments in note or folder paths. Zeppelin composes these into filesystem paths without ensuring they remain under the configured notebook directory, potentially allowing file move, write, or delete outside the notebook root.

Apache Zeppelin versions 0.11.1, 0.11.2, and 0.12.0 are vulnerable to LDAP filter injection. LdapRealm uses incorrect escaping (RFC 4514 instead of RFC 4515), leaving filter characters insufficiently escaped. This is an incomplete fix of CVE-2024-31867.

Apache Zeppelin versions 0.6.0 through 0.12.0 are vulnerable to LDAP injection. ActiveDirectoryGroupRealm constructs LDAP filters without escaping user input, allowing an authenticated attacker to inject filter syntax via the user-search endpoint.

Apache Zeppelin versions 0.6.0 through 0.12.0 are vulnerable to Cross-Site Request Forgery (CSRF). The default CORS configuration allows cross-origin state-changing requests and accepts text/plain bodies, enabling an attacker to perform actions on behalf of an authenticated user.
