Description
Privilege Defined With Unsafe Actions vulnerability in Apache Cassandra. An user with MODIFY permission ON ALL KEYSPACES can escalate privileges to superuser within a targeted Cassandra cluster via unsafe actions to a system resource. Operators granting data MODIFY permission on all keyspaces on affected versions should review data access rules for potential breaches. This issue affects Apache Cassandra 3.0.30, 3.11.17, 4.0.16, 4.1.7, 5.0.2, but this advisory is only for 4.0.16 because the fix to CVE-2025-23015 was incorrectly applied to 4.0.16, so that version is still affected. Users in the 4.0 series are recommended to upgrade to version 4.0.17 which fixes the issue. Users from 3.0, 3.11, 4.1 and 5.0 series should follow recommendation from CVE-2025-23015.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability in Apache Cassandra allows a user who has MODIFY permission on all keyspaces to escalate their privileges to superuser by performing unsafe actions on a system resource. Essentially, it means that someone with certain data modification rights can gain full administrative control over the Cassandra cluster.


How can this vulnerability impact me? :

If exploited, this vulnerability can allow an attacker with MODIFY permissions on all keyspaces to gain superuser privileges, potentially leading to unauthorized access, data breaches, or full control over the Cassandra cluster. This could compromise the integrity, confidentiality, and availability of your data and systems.


What immediate steps should I take to mitigate this vulnerability?

Review and restrict data MODIFY permissions on all keyspaces to prevent unauthorized privilege escalation. Specifically, avoid granting MODIFY permission ON ALL KEYSPACES to users unless absolutely necessary. For Apache Cassandra 4.0 series, upgrade to version 4.0.17 which contains the fix for this vulnerability. For other affected versions (3.0, 3.11, 4.1, and 5.0 series), follow the recommendations provided in CVE-2025-23015.
