An update of the erlang package has been released.

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 d87e2466-64d4-11f1-ab11-4c526214c986 advisory.

    https://github.com/erlang/otp/security/advisories/GHSA-m75x-4vwg-ggjh reports:
    The HTTP client (httpc) in inets now removes Authorization,               Proxy-Authorization, Cookie, Referer, and Origin headers when               following a redirect to a different host or port, following the               requirements of RFC 9110 section 15.4. Previously these headers               were forwarded verbatim, potentially leaking credentials to               unintended targets.

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.

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

  - Sensitive Data Exposure vulnerability in Erlang OTP inets (httpc_response module) allows Retrieve Embedded     Sensitive Data. The httpc client forwards the Authorization and Proxy-Authorization request headers to     redirect targets without checking whether the redirect crosses an origin boundary.
    httpc_response:redirect/2 constructs the redirected request by updating only the host field of the header     record; all other fields (including authorization and proxy_authorization) are copied verbatim. The     redirect target host is never compared against the original host. autoredirect defaults to true, so this     affects all httpc callers that do not explicitly disable automatic redirects. An attacker who controls a     server that the victim contacts via httpc can issue a cross-origin 3xx redirect to a server they also     control. The Authorization header (including Basic credentials derived from URL userinfo via     httpc_request:handle_user_info/2) is forwarded to the redirect target, allowing credential theft. The same     applies to the Proxy-Authorization header. This vulnerability is associated with program files     lib/inets/src/http_client/httpc_response.erl. This issue affects OTP from OTP 17.0 before OTP 27.3.4.13,     OTP 28.5.0.2, and OTP 29.0.2, corresponding to inets from 5.10 before 9.3.2.6, 9.6.2.2, and 9.7.1. Whether     OTP before OTP 17.0, corresponding to inets before 5.10, is affected is unknown. (CVE-2026-48856)

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

    Multiple vulnerabilities were discovered in Erlang/OTP, a concurrent,     real-time, distributed functional language, which may result in denial of     service, information disclosure, authentication and certificate validation     bypass, or the execution of arbitrary code. These vulnerbilities affect a     wide range of components: TLS and certificate validation (ssl, public_key),     SSH (ssh), network clients and servers (inets, ftp, epmd, kernel),     runtime and libraries (erts, erl_interface, stdlib, megaco).

    Several of these fixes tighten checks that were previously too permissive,     and can cause configurations that worked before to stop working. The most     likely to be noticed are:

     - TLS clients using verify_peer, which is the default, now reject        certificates that carry no subjectAltName extension; the        customize_hostname_check option does not restore the old behaviour.

     - Erlang distribution over TLS with the kernel 'check_ip' option now        enforces the check that was previously a no-op, so clusters whose nodes        are not on the same subnet lose distribution connectivity until the        option is unset.

     - TLS clients that request OCSP stapling now fail the handshake when the        server provides no stapled response.

     - Clients using TLS 1.2 or earlier now abort the handshake if the server        sends an ALPN extension that the client did not advertise.

     - DNS queries made through inet_res now use randomised source ports

    For the stable distribution (trixie), these problems have been fixed in     version 1:27.3.4.1+dfsg-1+deb13u3.

    We recommend that you upgrade your erlang packages.
