Weak Encoding for Password vulnerability in Mitsubishi Electric Corporation GOT2000 Series GT27 model versions 01.49.000 and prior, GT25 model versions 01.49.000 and prior, GT23 model versions 01.49.000 and prior, GT21 model versions 01.49.000 and prior, GOT SIMPLE Series GS25 model versions 01.49.000 and prior, GS21 model versions 01.49.000 and prior, GT Designer3 Version1 (GOT2000) versions 1.295H and prior and GT SoftGOT2000 versions 1.295H and prior allows a remote unauthenticated attacker to obtain plaintext passwords by sniffing packets containing encrypted passwords and decrypting the encrypted passwords, in the case of transferring data with GT Designer3 Version1(GOT2000) and GOT2000 Series or GOT SIMPLE Series with the Data Transfer Security function enabled, or in the case of transferring data by the SoftGOT-GOT link function with GT SoftGOT2000 and GOT2000 series with the Data Transfer Security function enabled.

Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') vulnerability in MITSUBSHI CNC Series allows a remote unauthenticated attacker to cause Denial of Service (DoS) condition and execute arbitrary code on the product by sending specially crafted packets. In addition, system reset is required for recovery.

Authentication Bypass by Capture-replay vulnerability in Mitsubishi Electric Corporation MELSEC iQ-F Series main modules allows a remote unauthenticated attacker to cancel the password/keyword setting and login to the affected products by sending specially crafted packets.

Unrestricted Upload of File with Dangerous Type 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 cause information disclosure, tampering, deletion or destruction via file upload/download. As a result, the attacker may be able to exploit this for further attacks.

Missing Password Field Masking vulnerability in Mitsubishi Electric Corporation EtherNet/IP configuration tools SW1DNN-EIPCT-BD and SW1DNN-EIPCTFX5-BD allows a remote unauthenticated attacker to know the password for MELSEC iQ-R Series EtherNet/IP module RJ71EIP91 and MELSEC iQ-F Series EtherNet/IP module FX5-ENET/IP. This vulnerability results in authentication bypass vulnerability, which allows the attacker to access MELSEC iQ-R Series EtherNet/IP module RJ71EIP91 and MELSEC iQ-F Series EtherNet/IP module FX5-ENET/IP via FTP.

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.
