Secunia Research has discovered some vulnerabilities in RealPage Module Upload ActiveX Control, which can be exploited by malicious people to gain knowledge of sensitive information or compromise a user's system.
1) A combination of the unsafe "Upload()" method and the "SourceFile" and "DestURL" properties allows uploading arbitrary files from a user's system to a web server.
2) A boundary error when handling the "SourceFile" property can be exploited to cause a heap-based buffer overflow by setting an overly long property value.
3) A boundary error when handling the "DestURL" property can be exploited to cause a stack-based buffer overflow by setting an overly long property value.
Successful exploitation of this vulnerability allows execution of arbitrary code.
The vulnerabilities are confirmed in version 220.127.116.11. Other versions may also be affected.
