Rewterz Threat Advisory – Siemens SIMATIC Panels and WinCC (TIA Portal) Multiple Vulnerabilities

May 16, 2019

Severity

Medium

Analysis Summary


CVE-2019-6572

The affected devices offer SNMP read/write capabilities with a hardcoded community string, which may allow an attacker to read/write variables over SNMP. This could compromise the confidentiality and integrity of the affected system.

CVE-2019-6576

An attacker with network access could potentially obtain a TLS session key and use it to decrypt TLS traffic. This could impact the confidentiality of communications between the device and a legitimate user.

CVE-2019-6577

The integrated web server could allow a cross-site scripting (XSS) attack if an attacker is able to modify certain device configuration settings via SNMP. This could impact confidentiality and integrity of the affected system.

Impact

  • Use of Hard-coded Credentials 
  • Insufficient Protection of Credentials 
  • Cross-site Scripting

Affected Vendors
