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.

Malwarebytes Binisoft Windows Firewall Control before 6.9.9.2 allows remote attackers to execute arbitrary code via gRPC named pipes.

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.

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.

Malwarebytes Anti-Exploit 4.4.0.220 is vulnerable to arbitrary file deletion and denial of service via an ALPC message in which FullFileNamePath lacks a '\0' character.

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."

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.

In Malwarebytes before 4.5.23, a symbolic link may be used delete any arbitrary file on the system by exploiting the local quarantine system. It can also lead to privilege escalation in certain scenarios.

In Malwarebytes Binisoft Windows Firewall Control before 6.8.1.0, programs executed from the Tools tab can be used to escalate privileges.

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.
