FreeBSD : Erlang/OTP -- FTP passive-mode client does not validate server response IP (d87e0681-64d4-11f1-ab11-4c526214c986)

medium Nessus Plugin ID 320573

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 d87e0681-64d4-11f1-ab11-4c526214c986 advisory.

https://github.com/erlang/otp/security/advisories/GHSA-24cv-hwgr-37fq reports:
The FTP client in passive mode did not validate the IP address returned in the server's response, allowing a compromised or malicious server to redirect the data connection to an arbitrary host. This enables server-side request forgery (SSRF) and FTP bounce attacks.

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.
