Multiple vulnerabilities have been discovered in Movicon, which can be exploited by malicious people to cause a DoS (Denial of Service) and compromise a vulnerable system.
1) An error when handling the "Content-Length" HTTP header can be exploited to cause a heap-based buffer overflow via a specially crafted web request sent to TCP port 808.
2) An error when handling HTTP packets can be exploited to cause a heap-based buffer overflow via a specially crafted packet sent to TCP port 808.
Successful exploitation of these vulnerabilities may allow execution of arbitrary code.
3) An error when handling web requests containing certain "EIDP" content can be exploited to crash the project server via a specially crafted web request sent to TCP port 808.
4) The application loads libraries (e.g. dwmapi.dll) in an insecure manner and can be exploited to load arbitrary libraries by tricking a user into e.g. opening a Project file (".movprj") located on a remote WebDAV or SMB share.
Successful exploitation of this vulnerability allows execution of arbitrary code.
The vulnerabilities are confirmed in version 11.2.1085. Other versions may also be affected.
Solution: Apply hot fix HotFix_Movicon11.2.1085.4, which fixes vulnerabilities #1, #2, and #3. Do not open untrusted Project files.
