ID CVE-2019-6574
Summary A vulnerability has been identified in SINAMICS PERFECT HARMONY GH180 with NXG I control, MLFBs: 6SR2...-, 6SR3...-, 6SR4...- (All Versions with option G21, G22, G23, G26, G28, G31, G32, G38, G43 or G46), SINAMICS PERFECT HARMONY GH180 with NXG II control, MLFBs: 6SR2...-, 6SR3...-, 6SR4...- (All Versions with option G21, G22, G23, G26, G28, G31, G32, G38, G43 or G46). An improperly configured Parameter Read/Write execution via Field bus network may cause the controller to restart. The vulnerability could be exploited by an attacker with network access to the device. Successful exploitation requires no privileges and no user interaction. An attacker could use the vulnerability to compromise the availability of the affected system. At the time of advisory publication no public exploitation of this security vulnerability was known.

Impact:
Exploitability:
CWE CWE-284
CAPEC
  • Embedding Scripts within Scripts
    An attack of this type exploits a programs' vulnerabilities that are brought on by allowing remote hosts to execute scripts. The attacker leverages this capability to execute scripts to execute his/her own script by embedding it within other scripts that the target software is likely to execute. The attacker must have the ability to inject script into script that is likely to be executed. If this is done, then the attacker can potentially launch a variety of probes and attacks against the web server's local environment, in many cases the so-called DMZ, back end resources the web server can communicate with, and other hosts. With the proliferation of intermediaries, such as Web App Firewalls, network devices, and even printers having JVMs and Web servers, there are many locales where an attacker can inject malicious scripts. Since this attack pattern defines scripts within scripts, there are likely privileges to execute said attack on the host. Of course, these attacks are not solely limited to the server side, client side scripts like Ajax and client side JavaScript can contain malicious scripts as well. In general all that is required is for there to be sufficient privileges to execute a script, but not protected against writing.
  • Signature Spoofing by Key Theft
    An attacker obtains an authoritative or reputable signer's private signature key by theft and then uses this key to forge signatures from the original signer to mislead a victim into performing actions that benefit the attacker.
