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

The upgrade functionality in Malwarebytes Anti-Malware (MBAM) consumer before 2.0.3 and Malwarebytes Anti-Exploit (MBAE) consumer 1.04.1.1012 and earlier allow man-in-the-middle attackers to execute arbitrary code by spoofing the update server and uploading an executable.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Malwarebytes Anti-Malware. 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.

Malwarebytes AdwCleaner before v.8.7.0 runs as Administrator and performs an insecure log file delete operation in which the target location is user-controllable, allowing a non-admin user to escalate privileges to SYSTEM via a symbolic link, a related issue to CVE-2023-28892. To exploit this, an attacker must create a file in a given folder path and intercept the application log file deletion flow.

Malwarebytes 4.5 contains an unquoted service path vulnerability in the MBAMService executable that allows local attackers to escalate privileges by injecting malicious code into the system root path. Attackers can place executable files in unquoted path directories that execute with LocalSystem privileges during service startup or system reboot.

The utility functions used by Malwarebytes EDR 1.0.11 on Linux for calculating a cryptographic hash of data bytes truncate the hashed data if it exceeds 4GB. This leads to an integer wrap-around if the data is larger than the maximum unsigned integer value (32-bit). Attackers could create a colliding hash value for two different strings by attaching 4GB of data to a string that is less than 4GB in size.

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 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.

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

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.

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 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.

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

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 LDLIBRARYPATH, set LDPRELOAD, or run an executable file in a debugger.
