Schneider-electric » Unity Pro : Security Vulnerabilities, CVEs, CVSS score >= 2

A CWE-123: Write-what-where Condition vulnerability exists in EcoStruxure™ Control Expert (all versions) and Unity Pro (former name of EcoStruxure™ Control Expert) (all versions), that could cause a crash of the software or unexpected code execution when opening a malicious file in EcoStruxure™ Control Expert software.

A CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection'), reflective DLL, vulnerability exists in EcoStruxure Control Expert (all versions prior to 14.1 Hot Fix), Unity Pro (all versions), Modicon M340 (all versions prior to V3.20), Modicon M580 (all versions prior to V3.10), which, if exploited, could allow attackers to transfer malicious code to the controller.

Incorrect Authorization vulnerability exists in EcoStruxure Control Expert (all versions prior to 14.1 Hot Fix), Unity Pro (all versions), Modicon M340 (all versions prior to V3.20) , and Modicon M580 (all versions prior to V3.10), which could cause a bypass of the authentication process between EcoStruxure Control Expert and the M340 and M580 controllers.

An issue was discovered in Schneider Electric Unity PRO prior to V11.1. Unity projects can be compiled as x86 instructions and loaded onto the PLC Simulator delivered with Unity PRO. These x86 instructions are subsequently executed directly by the simulator. A specially crafted patched Unity project file can make the simulator execute malicious code by redirecting the control flow of these instructions.

Stack-based buffer overflow in an unspecified DLL file in a DTM development kit in Schneider Electric Unity Pro, SoMachine, SoMove, SoMove Lite, Modbus Communication Library 2.2.6 and earlier, CANopen Communication Library 1.0.2 and earlier, EtherNet/IP Communication Library 1.0.0 and earlier, EM X80 Gateway DTM (MB TCP/SL), Advantys DTM for OTB, Advantys DTM for STB, KINOS DTM, SOLO DTM, and Xantrex DTMs allows remote attackers to execute arbitrary code via unspecified vectors.

Multiple stack-based buffer overflows in ModbusDrv.exe in Schneider Electric Modbus Serial Driver 1.10 through 3.2 allow remote attackers to execute arbitrary code via a large buffer-size value in a Modbus Application Header.

Buffer overflow in the UnitelWay Windows Device Driver, as used in Schneider Electric Unity Pro 6 and earlier, OPC Factory Server 3.34, Vijeo Citect 7.20 and earlier, Telemecanique Driver Pack 2.6 and earlier, Monitor Pro 7.6 and earlier, and PL7 Pro 4.5 and earlier, allows local users, and possibly remote attackers, to execute arbitrary code via an unspecified system parameter.
