CVE-2020-11639 — An attacker could exploit the vulnerability by injecting garbage data or specially crafted data

High CVSS 7.8

An attacker could exploit the vulnerability by injecting garbage data or specially crafted data. Depending on the data injected each process might be affected differently. The process could crash or cause communication issues on the affected node, effectively causing a denial-of-service attack. The attacker could tamper with the data transmitted, causing the product to store wrong information or act on wrong data or display wrong information. This issue affects Advant MOD 300 AdvaBuild: from 3.0 through 3.7 SP2. For an attack to be successful, the attacker must have local access to a node in the system and be able to start a specially crafted application that disrupts the communication. An attacker who successfully exploited the vulnerability would be able to manipulate the data in such way as allowing reads and writes to the controllers or cause Windows processes in 800xA for MOD 300 and AdvaBuild to crash.

General vulnerability remediation

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Confirm the affected component, deployment paths, reachable interfaces, and enabled features from inventories and configuration, without probing production destructively.
  • Compare the advisory's affected conditions with the repository lockfiles, build manifests, artifacts, and runtime inventory.
  • Identify data sensitivity, trust boundaries, and privilege level for every confirmed affected deployment.

Remediate safely

  • Apply a vendor-supported fix or remove the affected component or feature; record the selected change and its source in the repository.
  • Update direct and transitive dependency locks, generated artifacts, deployment manifests, and asset inventories together.
  • Add a regression test for the documented unsafe condition using inert inputs and preserve rollback instructions.
