Malwarebytes 4.5 Unquoted Service Path Privilege Escalation

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.

Windows Firewall Control 4.8.6.0 Unquoted Service Path Privilege Escalation

Windows Firewall Control 4.8.6.0 contains an unquoted service path vulnerability that allows local attackers to escalate privileges by inserting malicious executables in the service path. Attackers can place executable files in unquoted path directories that the wfcs.exe service will execute with LocalSystem privileges upon service restart or system reboot.

Hash Collision Due to 4GB Truncation in Malwarebytes EDR 1.0.11

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.

Heap Buffer Overflow in Malwarebytes Encryption Utilities

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.

Denial of Service via Large Firefox Preference Files in Malwarebytes

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.

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.

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

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.

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.

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 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.

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.

USB Flash Drives Control 4.1.0.0 Unquoted Service Path Privilege Escalation

USB Flash Drives Control 4.1.0.0 contains an unquoted service path vulnerability in its service configuration that allows local attackers to potentially execute arbitrary code. Attackers can exploit the unquoted path in 'C:\Program Files\USB Flash Drives Control\usbcs.exe' to inject malicious executables and escalate privileges on Windows systems.

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.

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

Malwarebytes Antimalware Link Following Local Privilege Escalation Vulnerability

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.

mbae.sys in Malwarebytes Anti-Exploit before 1.05.1.2014 allows local users to cause a denial of service (crash) via a crafted size in an unspecified IOCTL call, which triggers an out-of-bounds read. NOTE: some of these details are obtained from third party information.

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.

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.

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.
