A localhost.localdomain whitelist entry in valid_host() in scheduler/client.c in CUPS before 2.2.2 allows remote attackers to execute arbitrary IPP commands by sending POST requests to the CUPS daemon in conjunction with DNS rebinding. The localhost.localdomain name is often resolved via a DNS server (neither the OS nor the web browser is responsible for ensuring that localhost.localdomain is 127.0.0.1).

 https://vulnerability.circl.lu/vuln/usn-3577-1 USN-3577-1 — cups vulnerability 2026-09-30T11:11:58.465652+00:00

Affected: Ubuntu:14.04:LTS: cups, Ubuntu:16.04:LTS: cups

Jann Horn discovered that CUPS permitted HTTP requests with the Host header set to "localhost.localdomain" from the loopback interface. If a user were tricked in to opening a specially crafted website in their web browser, an attacker could potentially exploit this to obtain sensitive information or control printers, via a DNS rebinding attack. (CVE-2017-18190)
