New Flaws in Top Antivirus Software Could Make Computers More Vulnerable

An elevation of privilege vulnerability exists when the MpSigStub.exe for Defender allows file deletion in arbitrary locations. To exploit the vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted command that could exploit the vulnerability and delete protected files on an affected system once MpSigStub.exe ran again. The update addresses the vulnerability and blocks the arbitrary deletion.

A vulnerability in the web-based management interface of Cisco Webex Meetings Server Software could allow an unauthenticated, remote attacker to redirect a user to an undesired web page. The vulnerability is due to improper input validation of the URL parameters in an HTTP request that is sent to an affected device. An attacker could exploit this vulnerability by crafting an HTTP request that could cause the web application to redirect the request to a specified malicious URL. A successful exploit could allow the attacker to redirect a user to a malicious website.

A privilege escalation vulnerability in Trend Micro HouseCall for Home Networks (versions below 5.3.0.1063) could be exploited allowing an attacker to place a malicious DLL file into the application directory and elevate privileges.

A hard-link created from log file archive of Check Point ZoneAlarm up to 15.4.062 or Check Point Endpoint Security client for Windows before E80.96 to any file on the system will get its permission changed so that all users can access that linked file. Doing this on files with limited access gains the local attacker higher privileges to the file.

The installer of Kaspersky VPN Secure Connection prior to 5.0 was vulnerable to arbitrary file deletion that could allow an attacker to delete any file in the system.

Kaspersky Virus Removal Tool (KVRT) prior to 15.0.23.0 was vulnerable to arbitrary file corruption that could provide an attacker with the opportunity to eliminate content of any file in the system.

Installers of Kaspersky Security Center and Kaspersky Security Center Web Console prior to 12 & prior to 12 Patch A were vulnerable to a DLL hijacking attack that allowed an attacker to elevate privileges in the system.

Symbolic link manipulation vulnerability in McAfee Endpoint Security (ENS) for Windows prior to 10.7.0 February 2020 Update allows authenticated local user to potentially gain an escalation of privileges by pointing the link to files which the user which not normally have permission to alter via carefully creating symbolic links from the ENS log file directory.

Privilege Escalation vulnerability in the installer in McAfee McAfee Total Protection (MTP) trial prior to 4.0.161.1 allows local users to change files that are part of write protection rules via manipulating symbolic links to redirect a McAfee file operations to an unintended file.

An Unsafe Search Path vulnerability in FortiClient for Windows online installer 6.2.3 and below may allow a local attacker with control over the directory in which FortiClientOnlineInstaller.exe and FortiClientVPNOnlineInstaller.exe resides to execute arbitrary code on the system via uploading malicious Filter Library DLL files in that directory.
