What is CVE-2020-10620?

Opto 22 SoftPAC, up to and including version 9.6, contains a significant security flaw that permits unauthorized network communication. This vulnerability arises because SoftPAC does not utilize credential verification in its communication protocols. An attacker with network access can exploit this weakness to send commands directly to SoftPAC, potentially compromising the operation of the system, such as stopping the service remotely. Organizations using this product should mitigate risks by implementing network segmentation and access controls.
