Vulnerabilities

A Vulnerability is a state in a computing system (or set of systems) which either (a) allows an attacker to execute commands as another user, (b) allows an attacker to access data that is contrary to the specified access restrictions for that data, (c) allows an attacker to pose as another entity, or (d) allows an attacker to conduct a denial of service.Advisories relating to Symantec products may be viewed here.

Siemens SIMATIC IT UADM CVE-2019-13929 Hardcoded Cryptographic Key Vulnerability

Risk:
Medium
Date Discovered:
08 October 2019
Description:
Siemens SIMATIC IT UADM is prone to a hard-coded cryptographic key vulnerability. An attacker can exploit this issue to gain unauthorized access to the vulnerable device and perform unauthorized actions. Versions prior to SIMATIC IT UADM 1.3 are vulnerable.
Technologies Affected
  • Siemens SIMATIC IT Unified Architecture for Discrete Manufacturing 1.0
  • Siemens SIMATIC IT Unified Architecture for Discrete Manufacturing 1.1
  • Siemens SIMATIC IT Unified Architecture for Discrete Manufacturing 1.2
Recommendations
  • Block external access at the network boundary, unless external parties require service.
    If global access isn't needed, filter access to the affected computer at the network boundary. Restricting access to only trusted computers and networks might greatly reduce the likelihood of a successful exploit.
  • Run all software as a nonprivileged user with minimal access rights.
    To reduce the impact of latent vulnerabilities, always run nonadministrative software as an unprivileged user with minimal access rights.
  • Deploy network intrusion detection systems to monitor network traffic for malicious activity.
    Deploy NIDS to detect and block attacks and anomalous activity such as requests containing suspicious URI sequences. Since the webserver may log such requests, review its logs regularly.
Updates are available. Please see the references or vendor advisory for more information.
