Horner Automation Cscape ICSA-19-290-02 Multiple Arbitrary Code Execution Vulnerabilities



Date Discovered

October 17, 2019


Horner Automation Cscape is prone to multiple arbitrary code-execution vulnerabilities. Attackers can exploit these issues to execute arbitrary code within the context of the affected application, crash the device or obtain sensitive information. Versions prior to Horner Automation Cscape 9.90 SP1 are vulnerable.

Technologies Affected

  • Horner Automation Cscape 4
  • Horner Automation Cscape 8.0
  • Horner Automation Cscape 9.0
  • Horner Automation Cscape 9.3
  • Horner Automation Cscape 9.80
  • Horner Automation Cscape 9.80 SP1
  • Horner Automation Cscape 9.80 SP2
  • Horner Automation Cscape 9.80 SP4
  • Horner Automation Cscape
  • Horner Automation Cscape 9.90


Run all software as a nonprivileged user with minimal access rights.
To reduce the impact of latent vulnerabilities, run all applications with the minimal amount of privileges required for functionality.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Deploy NIDS to monitor network traffic for signs of suspicious or anomalous activity. This may help detect malicious actions that an attacker may take after successfully exploiting vulnerabilities in applications. Review all applicable logs regularly.

Implement multiple redundant layers of security.
Since this issue may be leveraged to execute code, we recommend memory-protection schemes, such as nonexecutable stack/heap configurations and randomly mapped memory segments. This tactic may complicate exploits of memory-corruption vulnerabilities.

Updates are available. Please see the references or vendor advisory for more information.
