Cisco Immunet and Cisco AMP for Endpoints System Scan Denial of Service

Priority: Medium
Advisory ID: cisco-sa-20181107-imm-dos
First Published: 2018 November 7 16:00 GMT
Version 1.0: Final
Workarounds: No workarounds available
Cisco Bug IDs: CSCvk70945 CSCvn05551
CVSS Score:
Base 5.5


  * A vulnerability in the system scanning component of Cisco Immunet and
    Cisco Advanced Malware Protection (AMP) for Endpoints running on Microsoft
    Windows could allow a local attacker to disable the scanning functionality
    of the product. This could allow executable files to be launched on the
    system without being analyzed for threats.

    The vulnerability is due to improper process resource handling. An attacker
    could exploit this vulnerability by gaining local access to a system
    running Microsoft Windows and protected by Cisco Immunet or Cisco AMP for
    Endpoints and executing a malicious file. A successful exploit could allow
    the attacker to prevent the scanning services from functioning properly and
    ultimately prevent the system from being protected from further intrusion.

    There are no workarounds that address this vulnerability.
