Security readout for executives and security teams

CVE-2009-2820 affects older CUPS print-server web interfaces. A remote attacker could make the interface return attacker-controlled browser content or malformed HTTP responses, creating XSS or response-splitting risk. Business urgency depends on whether legacy CUPS or old Mac OS X systems are still present and reachable. Exposure is most likely on legacy Unix/Linux print servers or Apple Mac OS X systems older than 10.6.2 running CUPS before 1.4.2, especially where the CUPS web interface is reachable by users or networks beyond trusted administrators. Prioritize remediation when old CUPS systems are internet-facing, shared across departments, or used by administrators. If CUPS is internal-only and patched by vendor packages, urgency is lower, but legacy systems should still be verified because print services are often overlooked. Mitigation focus: Upgrade CUPS to 1.4.2 or a vendor-fixed package.; Update Apple Mac OS X systems to 10.6.2 or later where applicable.; Review Red Hat, Apple, Mandriva, Sun, and CUPS advisories for platform-specific fixes..
