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.

    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

The versions of Primavera Unifier installed on the remote host are affected by multiple vulnerabilities as referenced in the October 2026 CPU advisory.

  - Vulnerability in the Primavera Unifier product of Oracle Construction and Engineering (component: Document     Management (Spring Framework)). Supported versions that are affected are 22.12.0-22.12.15,     23.12.0-23.12.16, 24.12.0-24.12.16 and 25.12.0-25.12.9. Difficult to exploit vulnerability allows     unauthenticated attacker with network access via HTTP to compromise Primavera Unifier. Successful attacks     of this vulnerability can result in unauthorized update, insert or delete access to some of Primavera     Unifier accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of     Primavera Unifier. (CVE-2026-22735, CVE-2026-22741, CVE-2026-22745, CVE-2026-41838, CVE-2026-41839,     CVE-2026-41840, CVE-2026-41841, CVE-2026-41842, CVE-2026-41843, CVE-2026-41844, CVE-2026-41845,     CVE-2026-41846, CVE-2026-41848, CVE-2026-41850, CVE-2026-41851, CVE-2026-41852, CVE-2026-41854,     CVE-2026-41855)

  - Vulnerability in the Primavera Unifier product of Oracle Construction and Engineering (component: Platform     (jsoup)). Supported versions that are affected are 21.12.0-21.12.17, 22.12.0-22.12.15, 23.12.0-23.12.16,     24.12.0-24.12.16 and 25.12.0-25.12.9. Easily exploitable vulnerability allows unauthenticated attacker     with network access via HTTP to compromise Primavera Unifier. Successful attacks of this vulnerability can     result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Primavera     Unifier. (CVE-2026-75140)

  - Vulnerability in the Primavera Unifier product of Oracle Construction and Engineering (component: Platform     (jackson-databind)). Supported versions that are affected are 21.12.0-21.12.17, 22.12.0-22.12.15,     23.12.0-23.12.16, 24.12.0-24.12.16 and 25.12.0-25.12.9. Easily exploitable vulnerability allows     unauthenticated attacker with network access via HTTP to compromise Primavera Unifier. Successful attacks     of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash     (complete DOS) of Primavera Unifier. (CVE-2026-19032, CVE-2026-68497, CVE-2026-91777)

  - Vulnerability in the Primavera Unifier product of Oracle Construction and Engineering (component: Core).
    Supported versions that are affected are 21.12.0-21.12.17. Difficult to exploit vulnerability allows     unauthenticated attacker with network access via HTTP to compromise Primavera Unifier. Successful attacks     of this vulnerability can result in unauthorized creation, deletion or modification access to critical     data or all Primavera Unifier accessible data as well as unauthorized access to critical data or complete     access to all Primavera Unifier accessible data. (CVE-2026-101736)

  - Vulnerability in the Primavera Unifier product of Oracle Construction and Engineering (component: Project     Control). Supported versions that are affected are 23.12.0-23.12.16. Easily exploitable vulnerability     allows low privileged attacker with network access via HTTP to compromise Primavera Unifier. Successful     attacks of this vulnerability can result in unauthorized creation, deletion or modification access to     critical data or all Primavera Unifier accessible data as well as unauthorized read access to a subset of     Primavera Unifier accessible data. (CVE-2026-101735)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The version of Apache ZooKeeper listening on the remote host is 3.8.x prior to 3.8.7 or 3.9.x prior to 3.9.6. It is, therefore, affected by multiple vulnerabilities:

  - Information disclosure via SetWatches reconnect replay due to a missing ACL check. An attacker     can discover ACL-restricted paths by registering exists-watches on non-existent paths, then     reconnecting after the paths are created with restricted ACLs. The SetWatches/SetWatches2     reconnect replay handler calls watcher.process(event) with null ACL, bypassing the check in     WatchManager.triggerWatch(). Only the path is exposed, not the znode data, but znode paths     can contain sensitive information such as usernames or login IDs. (CVE-2026-59739)

  - 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. (CVE-2026-59969)

  - The deleteContainer opcode (0x14/20) is processed without verifying the caller's ACL     permissions. A client that can open a plain TCP session on the ZooKeeper client port, with no     authentication and no ACL permissions, can delete any empty persistent znode, including     regular persistent nodes, container nodes and TTL nodes, by issuing the raw protocol     deleteContainer opcode. The deleteContainer request path skips both the session check and the     DELETE ACL check that are enforced by the regular delete path. (CVE-2026-79993)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - 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. (CVE-2026-59969)

Note that Nessus relies on the presence of the package as reported by the vendor.
