Use of Hard-coded Password vulnerability in FTP function on Mitsubishi Electric Corporation MELSEC iQ-R Series EtherNet/IP module RJ71EIP91 and MELSEC iQ-F Series EtherNet/IP module FX5-ENET/IP allows a remote unauthenticated attacker to obtain a hard-coded password and access to the module via FTP.

Weak Password Requirements vulnerability in FTP function on Mitsubishi Electric Corporation MELSEC iQ-R Series EtherNet/IP module RJ71EIP91 and MELSEC iQ-F Series EtherNet/IP module FX5-ENET/IP allows a remote unauthenticated attacker to access to the module via FTP by dictionary attack or password sniffing.

Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') vulnerability in Mitsubishi Electric Corporation MELSEC iQ-F Series CPU modules and MELSEC iQ-R Series CPU modules allows a remote unauthenticated attacker to cause a denial of service (DoS) condition or execute malicious code on a target product by sending specially crafted packets. A system reset of the product is required for recovery from a denial of service (DoS) condition and malicious code execution.

Active Debug Code vulnerability in Mitsubishi Electric Corporation MELSEC WS Series WS0-GETH00200 Serial number 2310 **** and prior allows a remote unauthenticated attacker to bypass authentication and illegally log into the affected module by connecting to it via telnet which is hidden function and is enabled by default when shipped from the factory. As a result, a remote attacker with unauthorized login can reset the module, and if certain conditions are met, he/she can disclose or tamper with the module's configuration or rewrite the firmware.

Signal Handler Race Condition vulnerability in Mitsubishi Electric India GC-ENET-COM whose first 2 digits of 11-digit serial number of unit are "16" allows a remote unauthenticated attacker to cause a denial-of-service (DoS) condition in Ethernet communication by sending a large number of specially crafted packets to any UDP port when GC-ENET-COM is configured as a Modbus TCP Server. The communication resumes only when the power of the main unit is turned off and on or when the GC-ENET-COM is hot-swapped from the main unit.

Plaintext Storage of a Password vulnerability in Mitsubishi Electric Corporation MELSEC iQ-F Series, MELSEC iQ-R Series, MELSEC-Q Series and MELSEC-L Series allows a remote unauthenticated attacker to disclose plaintext credentials stored in project files and login into FTP server or Web server.
