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.

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.

An authentication bypass vulnerability in FTP function in the EtherNet/IP module caused by weak password requirements may allow a remote unauthenticated attacker to access to the module via FTP by a dictionary attack or password sniffing. An authentication bypass vulnerability in the FTP function in the EtherNet/IP module caused by the use of hard-coded credentials may allow a remote unauthenticated attacker to obtain a hard-coded password and access to the module via FTP. The EtherNet/IP configuration tool displays an unmasked password due to the lack of password field masking may allow a remote unauthenticated attacker to access the module via FTP. An information disclosure, tampering, deletion, destruction vulnerability exists in the FTP function in the EtherNet/IP module via a file upload/download due to unrestricted upload of file with dangerous type.
