CyberRota Analysis
AI-GeneratedApache ZooKeeper in FIPS-mode deployments is vulnerable due to inadequate hostname verification when certain SSL configurations are enabled, allowing a malicious or misissued peer certificate to join quorum traffic. This could lead to unauthorized participation in leader elections and replication flows, compromising the integrity of the system. Organizations using affected versions should prioritize upgrading to versions 3.8.7 or 3.9.6 to mitigate this risk.
Original NVD Description
Apache ZooKeeper quorum TLS fails to enforce peer hostname verification in FIPS-mode deployments. When sslQuorum=true, zookeeper.fips-mode=true, ssl.quorum.hostnameVerification=true, and ssl.quorum.clientHostnameVerification=true are enabled, the Java SSLSocket quorum path accepts a CA-trusted peer certificate whose SAN does not match the connected host. A malicious or misissued peer certificate can therefore join quorum traffic, participate in leader election, and enter replication flows. Users are recommended to upgrade to version 3.8.7 or 3.9.6, which fixes the issue.
