Stack-based buffer overflow in the Chinagames CGAgent ActiveX control 1.x in CGAgent.dll, as distributed in Chinagames iGame 2009, allows remote attackers to execute arbitrary code via a long argument to the CreateChinagames method, as exploited in the wild in April and May 2009.

Security readout for executives and security teams

CVE-2009-1800 is a legacy Windows browser component issue in Chinagames iGame 2009. A vulnerable CGAgent ActiveX control could let a remote attacker run code if a user encountered malicious content. The source bundle says it was exploited in April and May 2009, but does not show current exploitation. Exposure is most likely on old Windows systems with Chinagames iGame 2009 or CGAgent.dll installed and browsers capable of loading ActiveX controls. Modern environments without this legacy software or ActiveX support are unlikely to be affected, based on the provided sources. Prioritize only if the organization still runs legacy Windows, Internet Explorer-era workflows, or Chinagames iGame 2009. For typical modern fleets, business urgency is likely low, but any confirmed installation should be removed or isolated because the bug enables code execution. Mitigation focus: Inventory endpoints for Chinagames iGame 2009 and CGAgent.dll.; Remove the Chinagames CGAgent ActiveX control where business use is not required.; Disable or restrict ActiveX execution on legacy browsers..
