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

  - Reliance on IP Address for Authentication vulnerability in Erlang/OTP ssl (inet_tls_dist module) allows     unauthenticated bypass of the distribution-over-TLS LAN allowlist. The inet_tls_dist:check_ip/1 function,     which enforces a LAN allowlist for Erlang distribution over TLS, calls inet:sockname/1 instead of     inet:peername/1 to obtain the peer's IP address. Because inet:sockname/1 returns the local socket address,     both the local IP and the supposed peer IP resolve to the same value, causing the subnet mask comparison     to always succeed regardless of the actual remote address. Any holder of a CA-signed TLS certificate can     therefore bypass the LAN restriction and gain full Erlang distribution access to the node, including     rpc:call/4 and code:load_binary/3. This vulnerability is associated with program file     lib/ssl/src/inet_tls_dist.erl. This issue affects OTP from OTP 26.0 before OTP 29.0.2, OTP 28.5.0.2 and     OTP 27.3.4.13, corresponding to ssl from 11.0 before 11.7.2, 11.6.0.2 and 11.2.12.9. (CVE-2026-48860)

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

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the d87e5fb4-64d4-11f1-ab11-4c526214c986 advisory.

    https://github.com/erlang/otp/security/advisories/GHSA-gp7x-mfv6-52cv reports:
    Erlang distribution over TLS run with the kernel check_ip               flag now properly enforces connecting nodes to be on the same               LAN. Previously the constraint was not enforced.

Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

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

An update of the erlang package has been released.

The remote Fedora 44 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-dcf80dc1ff advisory.

    Backport fixes for CVE-2026-48858 (ftp SSRF), CVE-2026-49759 (SCTP DoS), CVE-2026-48860 (dist-over-TLS     auth bypass), CVE-2026-54886 (ssh SFTP DoS), CVE-2026-54891 (TLS handshake data injection), and     CVE-2026-55952 (TLS 1.3 session ticket DoS). These are fixed upstream in OTP 27.x (rawhide/f45);
    backported here to the OTP 26.x line.
