Insufficiently Protected Credentials in PTC's Kepware KEPServerEX

An insufficiently protected credentials vulnerability in KEPServerEX could allow an adversary to capture user credentials as the web server uses basic authentication.

Uncontrolled Search Path Element in PTC's Kepware KEPServerEX

An uncontrolled search path element vulnerability (DLL hijacking) has been discovered that could allow a locally authenticated adversary to escalate privileges to SYSTEM.

Uncontrolled Search Path Element in PTC's Kepware KEPServerEX

An uncontrolled search path element vulnerability (DLL hijacking) has been discovered that could allow a locally authenticated adversary to escalate privileges to SYSTEM. Alternatively, they could host a trojanized version of the software and trick victims into downloading and installing their malicious version to gain initial access and code execution.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Kepware KEPServerEX 6.11.718.0. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of text encoding conversions. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of SYSTEM. Was ZDI-CAN-16486.

The specific flaw exists within the handling of text encoding conversions. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of SYSTEM. Was ZDI-CAN-18411.

Improper Input Validation in PTC's Kepware KEPServerEX

An improper input validation vulnerability has been discovered that could allow an adversary to inject a UNC path via a malicious project file. This allows an adversary to capture NLTMv2 hashes and potentially crack them offline.

KEPServerEX v6.0 to v6.9, ThingWorx Kepware Server v6.8 and v6.9, ThingWorx Industrial Connectivity (all versions), OPC-Aggregator (all versions), Rockwell Automation KEPServer Enterprise, GE Digital Industrial Gateway Server v7.68.804 and v7.66, and Software Toolbox TOP Server all 6.x versions, are vulnerable to a heap-based buffer overflow. Opening a specifically crafted OPC UA message could allow an attacker to crash the server and potentially leak data.
