Complexity

39%

Confidentiality

86%

A vulnerability exists in Rockwell Automation FactoryTalk® Service Platform that allows a malicious user to obtain the service token and use it for authentication on another FTSP directory. This is due to the lack of digital signing between the FTSP service token and directory.  If exploited, a malicious user could potentially retrieve user information and modify settings without any authentication.

CVSS 3.1 Base Score 9.1. CVSS Attack Vector: network. CVSS Attack Complexity: low. CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N).

Demo Examples

Improper Verification of Cryptographic Signature

CWE-347

In the following code, a JarFile object is created from a downloaded file.


               
JarFile jf = new JarFile(f);

The JAR file that was potentially downloaded from an untrusted source is created without verifying the signature (if present). An alternate constructor that accepts a boolean verify parameter should be used instead.
