Softing edgeConnector Siemens ConditionRefresh Resource Exhaustion Denial-of-Service Vulnerability

Softing edgeConnector Siemens ConditionRefresh Resource Exhaustion Denial-of-Service Vulnerability. This vulnerability allows remote attackers to create a denial-of-service condition on affected installations of Softing edgeConnector Siemens. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of OPC UA ConditionRefresh requests. By sending a large number of requests, an attacker can consume all available resources on the server. An attacker can leverage this vulnerability to create a denial-of-service condition on the system. Was ZDI-CAN-20498.

An uncaught exception issue discovered in Softing OPC UA C++ SDK before 6.30 for Windows operating system may cause the application to crash when the server wants to send an error packet, while socket is blocked on writing.

An issue was discovered in Softing OPC UA C++ SDK 5.66 through 6.x before 6.10. An OPC/UA browse request exceeding the server limit on continuation points may cause a use-after-free error

An issue was discovered in Softing OPC UA C++ SDK before 6.10. A buffer overflow or an excess allocation happens due to unchecked array and matrix bounds in structure data types.

Softing Secure Integration Server Relative Path Traversal

The “restore configuration” feature of Softing Secure Integration Server V1.22 is vulnerable to a directory traversal vulnerability when processing zip files. An attacker can craft a zip file to load an arbitrary dll and execute code. Using the "restore configuration" feature to upload a zip file containing a path traversal file may cause a file to be created and executed upon touching the disk.

Softing Secure Integration Server Uncontrolled Search Path Element

The application searches for a library dll that is not found. If an attacker can place a dll with this name, then the attacker can leverage it to execute arbitrary code on the targeted Softing Secure Integration Server V1.22.

Softing OPC-UA C++ SDK Improper Restriction of Operations within the Bounds of a Memory Buffer

Softing OPC UA C++ SDK (Software Development Kit) versions from 5.59 to 5.64 exported library functions don't properly validate received extension objects, which may allow an attacker to crash the software by sending a variety of specially crafted packets to access several unexpected memory locations.

Softing Secure Integration Server NULL Pointer Dereference

A crafted HTTP packet without a content-type header can create a denial-of-service condition in Softing Secure Integration Server V1.22.

Softing Secure Integration Server Improper Authentication

Softing Secure Integration Server, edgeConnector, and edgeAggregator software ships with the default administrator credentials as `admin` and password as `admin`. This allows Softing to log in to the server directly to perform administrative functions. Upon installation or upon first login, the application does not ask the user to change the `admin` password. There is no warning or prompt to ask the user to change the default password, and to change the password, many steps are required.

Softing Secure Integration Server NULL Pointer Dereference

Softing OPC UA C++ Server SDK, Secure Integration Server, edgeConnector, edgeAggregator, OPC Suite, and uaGate are affected by a NULL pointer dereference vulnerability.

Softing Secure Integration Server Integer Underflow

A crafted HTTP packet with a -1 content-length header can create a denial-of-service condition in Softing Secure Integration Server V1.22.

Softing Secure Integration Server Cleartext Transmission of Sensitive Information

Softing Secure Integration Server V1.22 is vulnerable to authentication bypass via a machine-in-the-middle attack. The default the administration interface is accessible via plaintext HTTP protocol, facilitating the attack. The HTTP request may contain the session cookie in the request, which may be captured for use in authenticating to the server.

Softing Secure Integration Server Out-of-bounds Read

A crafted HTTP packet with a large content-length header can create a denial-of-service condition in Softing Secure Integration Server V1.22.

Softing Secure Integration Server NULL Pointer Dereference

A crafted HTTP packet with a missing HTTP URI can create a denial-of-service condition in Softing Secure Integration Server V1.22.

An issue was discovered in Softing OPC UA C++ SDK before 5.70. A malformed OPC/UA message abort packet makes the client crash with a NULL pointer dereference.

An issue was discovered in Softing OPC UA C++ SDK before 5.70. An invalid XML element in the type dictionary makes the OPC/UA client crash due to an out-of-memory condition.
