Official description

Inadequate encryption strength for some Intel(R) PROSet/Wireless WiFi products may allow an unauthenticated user to potentially enable escalation of privilege via adjacent access.

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

The underlying weakness: Inadequate Encryption Strength

The product stores or transmits sensitive data using an encryption scheme that is theoretically sound, but is not strong enough for the level of protection required.

How developers prevent this class of flaw

  • Use an encryption scheme that is currently considered to be strong by experts in the field.
