CVE-2007-1483: Multiple PHP remote file inclusion vulnerabilities in WebCalendar 0.9.45 allow remote attackers to execute...

Security readout for executives and security teams

This is an old WebCalendar flaw where an attacker could make the application load PHP code from a remote location. If a vulnerable WebCalendar 0.9.45 instance is exposed, compromise could extend to the web server account and hosted calendar data. Exposure is limited to organizations still running WebCalendar 0.9.45, especially internet-facing deployments with the affected PHP scripts reachable. The CVE source bundle does not identify other affected versions or CPEs. Urgent only where WebCalendar 0.9.45 exists. For exposed vulnerable systems, prioritize remediation because the impact is remote code execution, not simple data disclosure. Mitigation focus: Identify and retire any WebCalendar 0.9.45 instances.; Review the WebCalendar 1.0.5 security patch announcement and vendor guidance.; Upgrade to a fixed supported WebCalendar release where applicable..
