CVE-2014-3686
Description
A command injection flaw was found in the way the wpa_cli utility executed action scripts. If wpa_cli was run in daemon mode to execute an action script (specified using the -a command line option), and wpa_supplicant was configured to connect to a P2P group, malicious P2P group parameters could cause wpa_cli to execute arbitrary code.
Statement
This issue did not affect the versions of wpa_supplicant as shipped with Red Hat Enterprise Linux 5 and 6.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)
Confidentiality,Integrity,Availability,Non-Repudiation
Technical Impact: Execute Unauthorized Code or Commands; DoS: Crash, Exit, or Restart; Read Files or Directories; Modify Files or Directories; Read Application Data; Modify Application Data; Hide Activities
Attackers could execute unauthorized operating system commands, which could then be used to disable the product, or read and modify data for which the attacker does not have permissions to access directly. Since the targeted application is directly executing the commands instead of the attacker, any malicious activities may appear to come from the application or the application's owner.
