What is CVE-2020-11639?

A vulnerability exists in the Advant MOD 300 AdvaBuild that could be exploited by an attacker with local access to inject specially crafted data. This malformed data can lead to various issues such as process crashes, communication breakdowns, or incorrect data being processed. The implications of this might include data integrity problems, resulting in the system storing or displaying erroneous information. An attacker's ability to manipulate the system could extend to reading and writing operations on controllers, potentially affecting other processes associated with Windows 800xA systems linked to MOD 300 and AdvaBuild. For successful exploitation, the attacker must execute a specifically crafted application that disrupts system communication.
