Melsec Q Series Qj71E71-100
The issue is related to the cleartext storage of sensitive information, specifically password hashes, in files. This allows a remote attacker to disclose or tamper with these files, potentially leading to privilege escalation. The vulnerability is associated with the unencrypted storage of credentials, which can be exploited by a remote attacker to gain elevated privileges using a file named 00000001.SYP.
