Malwarebytes Antimalware Link Following Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Malwarebytes Antimalware. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the Malwarebytes service. By creating a symbolic link, an attacker can abuse the service to delete a file. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM. Was ZDI-CAN-22321.Show less

In Malwarebytes EDR 1.0.11 for Linux, it is possible to bypass the detection layers that depend on inode identifiers, because an identifier may be reused when a file is replaced, and because two files on different filesystems can have the same identifier.Show less

The Malwarebytes EDR 1.0.11 for Linux driver doesn't properly ensure whitelisting of executable libraries loaded by executable files, allowing arbitrary code execution. The attacker can set LD_LIBRARY_PATH, set LD_PRELOAD, or run an executable file in a debugger.Show less

Lack of access control in wfc.exe in Malwarebytes Binisoft Windows Firewall Control 6.9.2.0 allows local unprivileged users to bypass Windows Firewall restrictions via the user interface's rules tab. NOTE: the vendor's perspective is "this is intended behavior as the application can be locked using a password."Show less

Malwarebytes AdwCleaner 8.4.0 runs as Administrator and performs an insecure file delete operation on C:\AdwCleaner\Logs\AdwCleaner_Debug.log in which the target location is user-controllable, allowing a non-admin user to escalate privileges to SYSTEM via a symbolic link.Show less

An issue was discovered in Malwarebytes before 4.0 on macOS. A malicious application was able to perform a privileged action within the Malwarebytes launch daemon. The privileged service improperly validated XPC connections by relying on the PID instead of the audit token. An attacker can construct a situation where the same PID is used for running two different programs at different times, by leveraging a race condition during crafted use of posix_spawn.Show less

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Malwarebytes Antimalware 3.6.1.2711. User interaction is required to exploit this vulnerability in that the target must visit a malicious web page. There is an issue with the way the product handles URIs within certain schemes. The product does not warn the user that a dangerous navigation is about to take place. Because special characters in the URI are not sanitized, this could lead to the execution of arbitrary commands. An attacker can leverage this vulnerability to execute code in the context of the current user at medium integrity. Was ZDI-CAN-7162.Show less

A vulnerability in the encryption and permission implementation of Malwarebytes Anti-Malware consumer version 2.2.1 and prior (fixed in 3.0.4) allows an attacker to take control of the whitelisting feature (exclusions.dat under %SYSTEMDRIVE%\ProgramData) to permit execution of unauthorized applications including malware and malicious websites. Files blacklisted by Malwarebytes Malware Protect can be executed, and domains blacklisted by Malwarebytes Web Protect can be reached through HTTP.Show less

In Malwarebytes Premium 3.3.1.2183, the driver file (FARFLT.SYS) allows local users to cause a denial of service (BSOD) or possibly have unspecified other impact because of not validating input values from IOCtl 0x9c40e02c. NOTE: the vendor reported that they "have not been able to reproduce the issue on any Windows operating system version (32-bit or 64-bit).Show less
