Netty is an asynchronous, event-driven network application framework. In versions prior to 4.1.132.Final and 4.2.10.Final, Netty incorrectly parses quoted strings in HTTP/1.1 chunked transfer encoding extension values, enabling request smuggling attacks. Versions 4.1.132.Final and 4.2.10.Final fix the issue.

According to its self-reported version number, the Oracle GoldenGate for Big Data application located on the remote host is affected by multiple vulnerabilities:

  - Vulnerability in the Oracle GoldenGate Big Data and Application Adapters product of Oracle GoldenGate     (component: Third Party (Eclipse Jetty)). Easily exploitable vulnerability allows unauthenticated attacker     with network access via HTTP to compromise Oracle GoldenGate Big Data and Application Adapters. Successful     attacks of this vulnerability can result in unauthorized access to critical data or complete access to all     Oracle GoldenGate Big Data and Application Adapters accessible data as well as unauthorized update, insert     or delete access to some of Oracle GoldenGate Big Data and Application Adapters accessible data.
    (CVE-2026-2332)

  - Vulnerability in the Oracle GoldenGate Big Data and Application Adapters product of Oracle GoldenGate     (component: Third Party (Netty)). Easily exploitable vulnerability allows unauthenticated attacker with     network access via HTTP to compromise Oracle GoldenGate Big Data and Application Adapters. Successful     attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable     crash (complete DOS) of Oracle GoldenGate Big Data and Application Adapters. (CVE-2026-33871)

  - Vulnerability in the Oracle GoldenGate Big Data and Application Adapters product of Oracle GoldenGate     (component: Third Party (Netty)). Easily exploitable vulnerability allows unauthenticated attacker with     network access via HTTP to compromise Oracle GoldenGate Big Data and Application Adapters. Successful     attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle     GoldenGate Big Data and Application Adapters accessible data. (CVE-2026-33870)

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 HCL BigFix Remote Control running on the remote host is 10.1.0.0442 or earlier. It is, therefore, affected by multiple vulnerabilities:

  - A misconfigured Content Security Policy (CSP) in HCL BigFix Remote Control Server WebUI (versions     10.1.0.0442 and earlier) fails to define directives without fallbacks, allowing attackers to bypass     intended security restrictions and load unauthorized resources. (CVE-2026-21785)

  - Netty incorrectly parses quoted strings in HTTP/1.1 chunked transfer encoding extension values, enabling     request smuggling attacks. (CVE-2026-33870)

  - Netty is an asynchronous, event-driven network application framework. In versions prior to 4.1.132.Final     and 4.2.10.Final, a remote user can trigger a Denial of Service (DoS) against a Netty HTTP/2 server by     sending a flood of CONTINUATION frames. The server's lack of a limit on the number of CONTINUATION frames,     combined with a bypass of existing size-based mitigations using zero-byte frames, allows an user to cause     excessive CPU consumption with minimal bandwidth, rendering the server unresponsive. (CVE-2026-33871)

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