McAfee DLPe Agent < 11.6.100.41 Multiple Vulnerabilities (SB10357)

high Nessus Plugin ID 148958

Language:

Synopsis

The remote host is affected by multiple vulnerabilities.

Description

The version of the McAfee Data Loss Prevention Endpoint (DLPe) Agent installed on the remote Windows host is prior to 11.6.100.41. It is, therefore, affected by multiple vulnerabilities:

- Denial of Service vulnerability in McAfee Data Loss Prevention (DLP) Endpoint for Windows prior to 11.6.100.41 allows a local, low privileged, attacker to cause a BSoD through suspending a process, modifying the processes memory and restarting it. This is triggered by the hdlphook driver reading invalid memory. (CVE-2021-23886)

- Privilege Escalation vulnerability in McAfee Data Loss Prevention (DLP) Endpoint for Windows prior to 11.6.100.41 allows a local, low privileged, attacker to write to arbitrary controlled kernel addresses.
This is achieved by launching applications, suspending them, modifying the memory and restarting them when they are monitored by McAfee DLP through the hdlphook driver. (CVE-2021-23887)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to McAfee DLPe 11.6.100.41 or later.
