Stack-based buffer overflow in Hummingbird.XWebHostCtrl.1 ActiveX control (hclxweb.dll) in Hummingbird Xweb ActiveX Control 13.0 and earlier allows remote attackers to execute arbitrary code via a long PlainTextPassword property. NOTE: code execution might not be possible in 13.0.

Security readout for executives and security teams

CVE-2008-4729 affects an old Hummingbird Xweb ActiveX browser control. A malicious web page could abuse an overly long password property to crash the control and potentially run code on the user’s machine. Risk is highest where legacy Internet Explorer and this ActiveX control remain in use. Exposure is likely limited to legacy Windows desktop environments that still have Hummingbird Xweb ActiveX Control 13.0 or earlier installed and allowed in the browser. Prioritize if the organization still runs legacy browser-based Hummingbird workflows. If absent, business urgency is low. If present on internet-browsing desktops, reduce exposure promptly because compromise would affect user workstations. Mitigation focus: Inventory and remove Hummingbird Xweb ActiveX Control where it is no longer required.; Disable or restrict the Hummingbird.XWebHostCtrl.1 ActiveX control in browsers.; Limit ActiveX execution to explicitly trusted internal sites only..
