In Eclipse Open9J versions 0.21 to 0.58, a pre-authentication remote attacker can crash JITServer by sending a 32-byte crafted TCP message.

The version of IBM Cognos Analytics installed on the remote host is 12.0.4 prior to 12.0.4 FP3, or 12.1.x prior to 12.1.3 FP2. It is, therefore, affected by multiple vulnerabilities as referenced in the IBM Security Bulletin No.
7287209:

  - NLTK versions 3.9.2 and prior are vulnerable to arbitrary code execution due to improper input     validation in the StanfordSegmenter module. The module dynamically loads external Java .jar files     without verification or sandboxing. An attacker can supply or replace the JAR file, enabling the     execution of arbitrary Java bytecode at import time. (CVE-2026-0848)

  - The lodash fix for CVE-2021-23337 added validation for the variable option in _.template but did not     apply the same validation to options.imports key names. Both paths flow into the same Function()     constructor sink. When an application passes untrusted input as options.imports key names, an attacker     can inject default-parameter expressions that execute arbitrary code at template compilation time.
    (CVE-2026-4800)

  - cryptography is a package designed to expose cryptographic primitives and recipes to Python developers.
    From 45.0.0 to before 46.0.7, if a non-contiguous buffer was passed to APIs which accepted Python     buffers (e.g. Hash.update()), this could lead to buffer overflows. (CVE-2026-39892)

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

The remote Redhat Enterprise Linux 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:22328 advisory.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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.

  - In Eclipse Open9J versions 0.21 to 0.58, a pre-authentication remote attacker can crash JITServer by     sending a 32-byte crafted TCP message. (CVE-2026-6918)

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