CVE-2007-6553: Multiple PHP remote file inclusion vulnerabilities in TeamCal Pro 3.1.000 and earlier allow remote attacker...

Security readout for executives and security teams

TeamCal Pro 3.1.000 and earlier allowed outsiders to point a configuration parameter at remote PHP code. If an affected installation is reachable, this could let an attacker run code on the server. The evidence identifies public exploit references, but not active exploitation. Exposure is likely limited to legacy TeamCal Pro deployments, especially internet-facing PHP installations running version 3.1.000 or earlier. Modern environments are only exposed if this old application remains deployed or archived under a live web root. Prioritize if TeamCal Pro is still internet-facing or on a sensitive server. The product and CVE are old, but the impact is server-side code execution. If no TeamCal Pro exists, document non-exposure and close. Mitigation focus: Inventory all TeamCal Pro instances and identify versions.; Remove or retire TeamCal Pro 3.1.000 and earlier where possible.; Check vendor or maintainer guidance for any supported fixed release..
