TITLE

Cisco Immunet Antimalware Installer input validation vulnerability

Trust: 0.8

sources: JVNDB: JVNDB-2017-010476

DESCRIPTION

An untrusted search path (aka DLL Preloading) vulnerability in the Cisco Immunet antimalware installer 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. Cisco Bug IDs: CSCvf23928. Vendors have confirmed this vulnerability Bug ID CSCvf23928 It is released as.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Cisco Immunet Antimalware is prone to a local privilege-escalation vulnerability. Local attackers may exploit this issue to execute arbitrary code with administrative privileges. installer is one of the installers
