In Mitsubishi Electric MELSEC-Q series Ethernet module QJ71E71-100 serial number 20121 and prior, an attacker could send crafted TCP packets against the FTP service, forcing the target devices to enter an error mode and cause a denial-of-service condition.
Mitsubishi Electric Q03/04/06/13/26UDVCPU: serial number 20081 and prior, Q04/06/13/26UDPVCPU: serial number 20081 and prior, and Q03UDECPU, Q04/06/10/13/20/26/50/100UDEHCPU: serial number 20101 and prior. A remote attacker can send specific bytes over Port 5007 that will result in an Ethernet stack crash and disruption to USB communication.
Mitsubishi E-Designer, Version 7.52 Build 344 contains two code sections which may be exploited to allow an attacker to overwrite arbitrary memory locations. This can result in arbitrary code execution, compromised data integrity, denial of service, and system crash.
Mitsubishi E-Designer, Version 7.52 Build 344 contains five code sections which may be exploited to overwrite the heap. This can result in arbitrary code execution, compromised data integrity, denial of service, and system crash.
Mitsubishi E-Designer, Version 7.52 Build 344 contains six code sections which may be exploited to overwrite the stack. This can result in arbitrary code execution, compromised data integrity, denial of service, and system crash.
An issue was discovered in Mitsubishi Electric Automation MELSEC-Q series Ethernet interface modules QJ71E71-100, all versions, QJ71E71-B5, all versions, and QJ71E71-B2, all versions. The affected Ethernet interface module is connected to a MELSEC-Q PLC, which may allow a remote attacker to connect to the PLC via Port 5002/TCP and cause a denial of service, requiring the PLC to be reset to resume operation. This is caused by an Unrestricted Externally Accessible Lock.
An issue was discovered in Mitsubishi Electric Automation MELSEC-Q series Ethernet interface modules QJ71E71-100, all versions, QJ71E71-B5, all versions, and QJ71E71-B2, all versions. Weakly encrypted passwords are transmitted to a MELSEC-Q PLC.
An ActiveX control in IcoLaunch.dll in Mitsubishi Electric Automation MC-WorX Suite 8.02 allows user-assisted remote attackers to execute arbitrary programs via a crafted HTML document in conjunction with a Login Client button click.
