CVSS Score: Base 6.7
o A vulnerability in the DLL loading component of Cisco Advanced Malware
Protection (AMP) for Endpoints on Windows could allow an authenticated,
local attacker to disable system scanning services or take other actions to
prevent detection of unauthorized intrusions. To exploit this
vulnerability, the attacker would need to have administrative credentials
on the Windows system.
The vulnerability is due to the improper validation of resources loaded by
a system process at run time. An attacker could exploit this vulnerability
by crafting a malicious DLL file and placing it in a specific location on
the targeted system. A successful exploit could allow the attacker to
disable the targeted system's scanning services and ultimately prevent the
system from being protected from further intrusion.
There are no workarounds that address this vulnerability.
