Issue/Introduction

Does Carbon Black Alert on this Action found in this CVE?

Environment

• Carbon Black Cloud:  All Products

Resolution

• No, the actions seen by the abuse of a CVE are normally within the normal operations of usage.  Creating a new specific rule for each CVE would not be maintainable.

Example:  If the CVE reports Firefox versions < 82.0.3 (CVE-2020-26950) are vulnerable.  Alerts should not occur for each use of Firefox.  Instead, the vulnerability requires a certain environmental configuration before or after Firefox start that should alert.
 

• Potential next steps:
  • Check TAU for any reports regarding the CVE.  A report on a threat is provided on an as-needed basis based on multiple factors.
  • Understand the CVE.
  • Understand if/how the common software is used in the network.
  • Determine if a custom watchlist is warranted to monitor any misuse of the commonly used software.
  • Contact Support to express interest in a particular threat or possibly get more information.
