FreeBSD : FreeIPA -- multiple vulnerabilities (4d2a90c7-df51-11f1-a655-3497f65b111b)

medium Nessus Plugin ID 381296

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 multiple vulnerabilities as referenced in the 4d2a90c7-df51-11f1-a655-3497f65b111b advisory.

The FreeIPA project reports:
CVE-2026-53683: client-side open redirect in reset_password.html.
The page takes the url query parameter as a redirection target without validating or allow-listing it, so an attacker can send a user to an arbitrary site once the password reset completes. No authentication is required, and the link appears to come from the IdM domain, which makes it useful for phishing.
CVE-2026-86593: unauthenticated denial of service in the session endpoints login_password, change_password and sync_token. They do not limit the size of the request body, so an attacker can tie up the WSGI worker pool. That pool serves the whole /ipa application, so exhausting it also denies the Kerberos authenticated paths such as the web interface and the admin RPC. This is the same root cause already fixed for i18n_messages and migration.py, whose fix covered only a single caller.

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

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

Solution

Update the affected packages.
