Insufficient restriction of IPP filters in CUPS in Google Chrome OS prior to 62.0.3202.74 allowed a remote attacker to execute a command with the same privileges as the cups daemon via a crafted PPD file, aka a printer zeroconfig CRLF issue.

Security readout for executives and security teams

Plain-English summary

This flaw allowed a remote attacker to make vulnerable Chrome OS CUPS printing components run a command with cups daemon privileges using a crafted printer description file. It matters most where legacy Chrome OS or unpatched CUPS-based systems still support printer discovery or IPP handling.

Executive priority

Prioritize remediation where printing services are enabled on unmanaged, legacy, or network-exposed systems. This is not confirmed as actively exploited in the provided evidence, but remote command execution in a printing service is a meaningful operational risk.

Technical view

CVE-2017-15400 is an insufficient restriction issue in IPP filters in CUPS, described as a printer zeroconfig CRLF issue. A crafted PPD file could trigger command execution with cups daemon privileges. The named affected product is Google Chrome OS before 62.0.3202.74; Debian and Gentoo also published CUPS advisories referencing related fixes.

Likely exposure

Exposure is most likely in obsolete Chrome OS deployments before 62.0.3202.74 or Linux systems with CUPS packages covered by the Debian and Gentoo advisories. Modern managed Chrome OS fleets are less likely exposed if they have long since received stable-channel updates.

Exploitation context

The provided bundle does not show CISA KEV listing or other evidence of active exploitation. The impact is still serious because the vulnerability is remote and reaches command execution under the cups daemon account through crafted printer configuration content.

Researcher notes

The bundle lacks CVSS, CWE, and detailed exploitability conditions. Treat affected scope conservatively: Chrome OS before 62.0.3202.74 is explicitly named, while Debian and Gentoo advisories indicate CUPS package relevance. Avoid claiming broader product impact without vendor confirmation.

Mitigation direction

  • Update Chrome OS devices to 62.0.3202.74 or later.
  • Apply CUPS security updates from the relevant Linux distribution advisory.
  • Check Debian DSA-4243 for affected package guidance.
  • Check Gentoo GLSA-201908-08 for affected package guidance.
  • Limit printer discovery and IPP exposure while awaiting vendor-approved fixes.

Validation and detection

  • Inventory Chrome OS devices older than 62.0.3202.74.
  • Identify Linux hosts running CUPS packages covered by DSA-4243 or GLSA-201908-08.
  • Confirm CUPS package versions match vendor-fixed releases.
  • Review whether printer discovery or IPP is reachable from untrusted networks.
  • Check for unexpected printer configuration changes on exposed systems.
