Multiple components of Iconics SCADA Suite are prone to a Phantom DLL loading vulnerability. This issue arises from the applications improperly searching for and loading dynamic link libraries, potentially allowing an attacker to execute malicious code via a DLL with a matching name in an accessible search path.

Sim2ComProc.dll
MMXCall_in.exe * libdxxmt.dll
libsrlmt.dll
The product searches for critical resources using an externally-supplied search path that can point to resources that are not under the product’s direct control.
| Name | Vendor | Start Version | End Version |
|---|---|---|---|
| Iconics_suite | Iconics | * | 10.97.2 (excluding) |

If the product uses a search path to locate critical resources such as programs, then an attacker could modify that search path to point to a malicious program, which the targeted product would then execute. The problem extends to any type of critical resource that the product trusts. Some of the most common variants of untrusted search path are:
