Official description

Download of code without integrity check vulnerability in N-able N-central allows Remote Code Inclusion. This issue affects N-central: through 24.6.1.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: Download of Code Without Integrity Check

The product downloads source code or an executable from a remote location and executes the code without sufficiently verifying the origin and integrity of the code.

How developers prevent this class of flaw

  • Perform proper forward and reverse DNS lookups to detect DNS spoofing.
  • Encrypt the code with a reliable encryption scheme before transmitting.
  • Run your code using the lowest privileges that are required to accomplish the necessary tasks. If possible, create isolated accounts with limited privileges that are only used for a single task. That way, a successful attack will not immediately give the attacker access to the rest of the software or its environment. For example, database applications rarely need to run as the database administrator, especially in day-to-day operations.
