FreeBSD : Erlang/OTP -- httpc leaks authentication headers on cross-host redirect (d87e2466-64d4-11f1-ab11-4c526214c986)

high Nessus Plugin ID 320576

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

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.

Solution

Update the affected packages.
