CVE-2024-27137 | Apache Cassandra: unrestricted deserialization of JMX authentication credentials

In Apache Cassandra it is possible for a local attacker without access to the Apache Cassandra process or configuration files to manipulate the RMI registry to perform a man-in-the-middle attack and capture user names and passwords used to access the JMX interface. The attacker can then use these credentials to access the JMX interface and perform unauthorized operations. This is same vulnerability that CVE-2020-13946 was issued for, but the Java option was changed in JDK10. This issue affects Apache Cassandra from 4.0.2 through 5.0.2 running Java 11. Operators are recommended to upgrade to a release equal to or later than 4.0.15, 4.1.8, or 5.0.3 which fixes the issue.

5.3 3.1 MEDIUM
CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:L Click to expand
Attack vector (AV:L)
They already need access on the box, or another person has to do something wrong; it’s not a remote drive-by.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:R)
A real person has to do something—click, install, enable—otherwise it doesn’t land.
Scope (S:U)
Damage stays in the same “trust bubble” as the broken component—no big spill into unrelated systems.
Confidentiality (C:L)
Some sensitive info could get out, but not a total data dump.
Integrity (I:L)
Attackers could change some data, but it’s limited—not everything goes.
Availability (A:L)
Might cause slowdowns, glitches, or partial disruption—not a full brick.
