Package : zookeeper Version : 3.4.13-2+deb10u1 CVE ID : CVE-2023-44981 Debian Bug : 1054224

It was discovered that there was a potential authorisation bypass vulnerability in Apache Zookeeper, a co-ordination service for reliable distributed applications.

Specifically, if SASL Quorum Peer authentication was enabled via quorum.auth.enableSasl, authorisation was performed by verifying that the instance part in the SASL authentication ID was listed in the zoo.cfg server list. However, this value is optional, and, if missing (such as in '[email protected]'), the authorisation check will be skipped. As a result, an arbitrary endpoint could join the cluster and begin propagating counterfeit changes to the leader, essentially giving it complete read-write access to the data tree.

For Debian 10 buster, this problem has been fixed in version 3.4.13-2+deb10u1.

We recommend that you upgrade your zookeeper packages.

For the detailed security status of zookeeper please refer to its security tracker page at:
