An issue was discovered in Malwarebytes before 4.6.14.326 and before 5.1.5.116 (and Nebula 2020-10-21 and later). Out-of-bound reads in strings detection utilities lead to system crashes.

An issue was discovered in Malwarebytes 4.6.14.326 and before 5.1.5.116 (and Nebula 2020-10-21 and later). A Stack buffer out-of-bounds access exists because of an integer underflow when handling newline characters.

An issue was discovered in Malwarebytes 4.6.14.326 and before and 5.1.5.116 and before (and Nebula 2020-10-21 and later). An Out of bounds read in several disassembling utilities causes stability issues and denial of service.

In Malwarebytes Binisoft Windows Firewall Control before 6.16.0.0, the installer is vulnerable to local privilege escalation.

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.

An issue in Malwarebytes Premium Security v5.0.0.883 allows attackers to execute arbitrary code via placing crafted binaries into unspecified directories. NOTE: Malwarebytes argues that this issue requires admin privileges and that the contents cannot be altered by non-admin users.

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.

In Malwarebytes Free 4.1.0.56, a symbolic link may be used delete an arbitrary file on the system by exploiting the local quarantine system.

An Untrusted Search Path vulnerability in Malwarebytes AdwCleaner 8.0.3 could cause arbitrary code execution with SYSTEM privileges when a malicious DLL library is loaded.

An Untrusted Search Path vulnerability in Malwarebytes AdwCleaner before 8.0.1 could cause arbitrary code execution with SYSTEM privileges when a malicious DLL library is loaded by the product.

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.

malwarebytes

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.

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).
