When using IPAuthenticationProvider in ZooKeeper Admin Server there is a possibility of Authentication Bypass by Spoofing -- this only impacts IP based authentication implemented in ZooKeeper Admin Server. Default configuration of client's IP address detection in IPAuthenticationProvider, which uses HTTP request headers, is weak and allows an attacker to bypass authentication via spoofing client's IP address in request headers. Default configuration honors X-Forwarded-For HTTP header to read client's IP address. X-Forwarded-For request header is mainly used by proxy servers to identify the client and can be easily spoofed by an attacker pretending that the request comes from a different IP address. Admin Server commands, such as snapshot and restore arbitrarily can be executed on successful exploitation which could potentially lead to information leakage or service availability issues. Users are recommended to upgrade to version 3.9.3, which fixes this issue.

The versions of Oracle E-Business Suite installed on the remote host are affected by multiple vulnerabilities as referenced in the April 2026 CPU advisory.

  - Vulnerability in the Oracle Advanced Inbound Telephony product of Oracle E-Business Suite (component:
    Setup and Administration). Supported versions that are affected are 12.2.3-12.2.15. Easily exploitable     vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Advanced     Inbound Telephony. Successful attacks of this vulnerability can result in takeover of Oracle Advanced     Inbound Telephony. (CVE-2026-34275)

  - Vulnerability in the Oracle Enterprise Command Center Framework product of Oracle E-Business Suite     (component: Core (Apache ZooKeeper)). The supported version that is affected is 15.0. Easily exploitable     vulnerability allows unauthenticated attacker with network access via TCP to compromise Oracle Enterprise     Command Center Framework. Successful attacks of this vulnerability can result in unauthorized access to     critical data or complete access to all Oracle Enterprise Command Center Framework accessible data and     unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle Enterprise     Command Center Framework. (CVE-2024-51504)

  - Vulnerability in the Oracle Advanced Supply Chain Planning, Oracle Flow Manufacturing, Oracle Global Order     Promising, Oracle iProcurement, Oracle Rapid Planning, and Oracle Yard Management products of Oracle     E-Business Suite (component: Apache Commons BeanUtils). Supported versions that are affected are     12.2.3-12.2.15 (Yard Management 12.2.4-12.2.15). Easily exploitable vulnerability allows low privileged     attacker with network access via HTTP to compromise these products. Successful attacks of this     vulnerability can result in takeover of these products. (CVE-2025-48734)

  - Vulnerability in the Oracle Applications DBA product of Oracle E-Business Suite (component: ADPatch).
    Supported versions that are affected are 12.2.3-12.2.15. Difficult to exploit vulnerability allows high     privileged attacker with network access via HTTP to compromise Oracle Applications DBA. Successful attacks     require human interaction from a person other than the attacker and while the vulnerability is in Oracle     Applications DBA, attacks may significantly impact additional products (scope change). Successful attacks     of this vulnerability can result in takeover of Oracle Applications DBA. (CVE-2026-22011)

  - Vulnerability in the Oracle Enterprise Command Center Framework product of Oracle E-Business Suite     (component: ECC Core (Netty)). The supported version that is affected is 15.0. Easily exploitable     vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Enterprise     Command Center Framework. Successful attacks of this vulnerability can result in unauthorized ability to     cause a hang or frequently repeatable crash (complete DOS) of Oracle Enterprise Command Center Framework.
    (CVE-2025-58057)

  - Vulnerability in the Oracle HCM Common Architecture product of Oracle E-Business Suite (component:
    Knowledge Integration). Supported versions that are affected are 12.2.3-12.2.15. Easily exploitable     vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle HCM Common     Architecture. Successful attacks of this vulnerability can result in unauthorized update, insert or delete     access to some of Oracle HCM Common Architecture accessible data as well as unauthorized read access to a     subset of Oracle HCM Common Architecture accessible data. (CVE-2026-34297)

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

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - When using IPAuthenticationProvider in ZooKeeper Admin Server there is a possibility of Authentication
    Bypass by Spoofing -- this only impacts IP based authentication implemented in ZooKeeper Admin Server.
    Default configuration of client's IP address detection in IPAuthenticationProvider, which uses HTTP
    request headers, is weak and allows an attacker to bypass authentication via spoofing client's IP address
    in request headers. Default configuration honors X-Forwarded-For HTTP header to read client's IP address.
    X-Forwarded-For request header is mainly used by proxy servers to identify the client and can be easily
    spoofed by an attacker pretending that the request comes from a different IP address. Admin Server
    commands, such as snapshot and restore arbitrarily can be executed on successful exploitation which could
    potentially lead to information leakage or service availability issues. Users are recommended to upgrade
    to version 3.9.3, which fixes this issue. (CVE-2024-51504)

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

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

The version of Apache ZooKeeper listening on the remote host is 3.9.x prior to 3.9.3. It is, therefore, affected by an authentication bypass vulnerability:
