A vulnerability in the endpoint software of Cisco Secure Endpoint for Windows could allow an authenticated, local attacker to evade endpoint protection within a limited time window.
This vulnerability is due to a timing issue that occurs between various software components. An attacker could exploit this vulnerability by persuading a user to put a malicious file into a specific folder and then persuading the user to execute the file within a limited time window. A successful exploit could allow the attacker to cause the endpoint software to fail to quarantine the malicious file or kill its process.
Note: This vulnerability only applies to deployments that have the Windows Folder Redirection feature enabled.
Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
