CVE-2009-1516: Stack-based buffer overflow in the IceWarpServer.APIObject ActiveX control in api.dll in IceWarp Merak Mail...

Stack-based buffer overflow in the IceWarpServer.APIObject ActiveX control in api.dll in IceWarp Merak Mail Server 9.4.1 might allow context-dependent attackers to execute arbitrary code via a large value in the second argument to the Base64FileEncode method, as possibly demonstrated by a web application that accepts untrusted input for this method.

Security readout for executives and security teams

This old CVE describes a memory corruption flaw in an IceWarp Merak Mail Server ActiveX component. If vulnerable code is reachable through an application that passes untrusted input to it, an attacker might run code in that context. The sources do not provide CVSS, confirmed active exploitation, or a vendor fix. Most likely exposure is legacy IceWarp Merak Mail Server 9.4.1 deployments, or systems retaining its api.dll ActiveX control, especially where a web application accepts untrusted input and passes it into Base64FileEncode. Treat as a high-priority legacy exposure issue if IceWarp Merak 9.4.1 exists in the environment. The main business risk is arbitrary code execution through obsolete components, but urgency depends on whether the ActiveX control is installed and reachable. Mitigation focus: Check IceWarp vendor guidance for supported fixes or replacement versions.; Inventory and retire unsupported IceWarp Merak Mail Server 9.4.1 deployments.; Remove or disable the APIObject ActiveX control where it is not required..
