Detailsinfo

A vulnerability was found in Cisco Network Academy Packet Tracer (unknown version). It has been classified as problematic. Affected is an unknown code block. The manipulation as part of a Search Path leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

An untrusted search path (aka DLL Preload) vulnerability in the Cisco Network Academy Packet Tracer software could allow an authenticated, local attacker to execute arbitrary code via DLL hijacking if a local user with administrative privileges executes the installer in the current working directory where a crafted DLL has been placed by an attacker. The vulnerability is due to incomplete input validation of path and file names of a DLL file before it is loaded. An attacker could exploit this vulnerability by creating a malicious DLL file and installing it in a specific system directory. A successful exploit could allow the attacker to execute commands on the underlying Microsoft Windows host with privileges equivalent to the SYSTEM account. An attacker would need valid user credentials to exploit this vulnerability.

The bug was discovered 11/15/2017. The weakness was shared 11/16/2017 by Kushal Arvind Shah with Fortinet's FortiGuard Labs as cisco-sa-20171115-cpt as confirmed advisory (Website). The advisory is shared for download at tools.cisco.com. This vulnerability is traded as CVE-2017-12313 since 08/03/2017. The attack needs to be approached locally.
