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.

An issue was discovered in Malwarebytes 4.x and 5.x (and Nebula 2020-10-21 and later). There is a Heap buffer overflow in various buffer encryption utilities.

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.

An issue was discovered in Malwarebytes 4.x and 5.x (and Nebula 2020-10-21 and later). A large number of Firefox preference files can cause the parser to ignore other browser configuration files, leading to a denial of service.

This vulnerability allows local attackers to escalate privileges on affected installations of Malwarebytes Anti-Malware. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The ZDI has assigned a CVSS rating of 7.8.

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 1.0.14 for Linux doesn't properly compute signatures in some scenarios. This allows a bypass of detection.

In Malwarebytes For Teams v.1.0.990 and before and fixed in v.1.0.1003 and later a privilege escalation can occur via the COM interface running in mbamservice.exe.

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.

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 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 before 4.6.14.326 and before 5.1.5.116 (and Nebula 2020-10-21 and later). There is a Race condition that leads to code execution because of a lack of locks between file verification and execution.

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.

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.

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 LDLIBRARYPATH, set LDPRELOAD, 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.

DISPUTED 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\AdwCleanerDebug.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 posixspawn.

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.
