Title
Arbitrary code execution in MobaXterm Personal Edition (Portable)
Summary
MobaXterm Personal Edition (Portable), in its 26.3 version (Build 5154), allows arbitrary code execution by loading malicious DLLs from a temporary directory that is predictable and can be modified by the user. During startup, the application searches for specific DLLs in this location before resorting to the system’s secure paths, enabling an attacker with local access to place a specially crafted DLL to be executed automatically when the victim launches the application.

CVE-2026-7373 (GCVE-0-2026-7373)

Vulnerability from cvelistv5 – Published: 2026-05-15 02:06 – Updated: 2026-05-19 22:43

Title
Metasploit Pro on Windows: Local Privilege Escalation via OpenSSL Configuration File Loading
Summary
Rapid7 Metasploit Pro is vulnerable to a local privilege escalation attack that allows a user to gain SYSTEM level control of a Windows host. When started the metasploitPostgreSQL service would start the postgres.exe child process which would in turn load an OpenSSL configuration file from a static location. This static location would be writable by a pre-existing "vagrant" user, if they already existed on the system. Metasploit does not create local accounts, an Administrator would need to create it. By planting a crafted openssl.cnf file an attacker can trick the high-privilege service into executing arbitrary commands. This effectively permits the unprivileged vagrant user to bypass security controls and achieve a full host compromise under the agent's SYSTEM level access.

CVE-2026-6645 (GCVE-0-2026-6645)

Vulnerability from cvelistv5 – Published: 2026-06-22 03:24 – Updated: 2026-06-23 03:55

Title
Insecure Search Path Vulnerability in PaperCut Print Deploy Client for Windows
Summary
An insecure process execution vulnerability exists in the pc-printer-updater.exe component of the PaperCut Print Deploy Client for Windows. The application, which typically operates with high-level system privileges, attempts to perform an internal validation check by invoking a secondary system utility using an unqualified file reference. Because the application does not specify an absolute path to this utility, it relies on the operating system's default search order to locate the executable. Under specific conditions, a local attacker with the ability to modify directories within the system's search path could plant a malicious binary that mimics the expected utility. This could result in the malicious code being executed with SYSTEM privileges, leading to a full compromise of the affected host.

Title
Vulnerability Related to an Uncontrolled Search Path Element in a UPS Management Application
Summary
It has been identified that a vulnerability (CWE-427) exists in the UPS (Uninterruptible Power Supply) management application, whereby improper permissions on the installation directory allow a malicious actor to place a DLL that is then executed with administrator privileges. If a malicious DLL is placed in the installation directory of this product, there is a possibility that the malicious DLL may be executed by exploiting the product’s behavior of loading missing DLLs from the same directory as the executable during service startup.

Mitigation
Architecture and Design Implementation

Strategy: Attack Surface Reduction

Hard-code the search path to a set of known-safe values (such as system directories), or only allow them to be specified by the administrator in a configuration file. Do not allow these settings to be modified by an external party. Be careful to avoid related weaknesses such as CWE-426 and CWE-428.

Mitigation
Implementation

Strategy: Attack Surface Reduction

When invoking other programs, specify those programs using fully-qualified pathnames. While this is an effective approach, code that uses fully-qualified pathnames might not be portable to other systems that do not use the same pathnames. The portability can be improved by locating the full-qualified paths in a centralized, easily-modifiable location within the source code, and having the code refer to these paths.

Mitigation
Implementation

Strategy: Attack Surface Reduction

Remove or restrict all environment settings before invoking other programs. This includes the PATH environment variable, LD_LIBRARY_PATH, and other settings that identify the location of code libraries, and any application-specific search paths.

Mitigation
Implementation

Check your search path before use and remove any elements that are likely to be unsafe, such as the current working directory or a temporary files directory. Since this is a denylist approach, it might not be a complete solution.

Mitigation
Implementation

Use other functions that require explicit paths. Making use of any of the other readily available functions that require explicit paths is a safe way to avoid this problem. For example, system() in C does not require a full path since the shell can take care of finding the program using the PATH environment variable, while execl() and execv() require a full path.

CAPEC-38: Leveraging/Manipulating Configuration File Search Paths

This pattern of attack sees an adversary load a malicious resource into a program's standard path so that when a known command is executed then the system instead executes the malicious component. The adversary can either modify the search path a program uses, like a PATH variable or classpath, or they can manipulate resources on the path to point to their malicious components. J2EE applications and other component based applications that are built from multiple binaries can have very long list of dependencies to execute. If one of these libraries and/or references is controllable by the attacker then application controls can be circumvented by the attacker.

CAPEC-471: Search Order Hijacking

An adversary exploits a weakness in an application's specification of external libraries to exploit the functionality of the loader where the process loading the library searches first in the same directory in which the process binary resides and then in other directories. Exploitation of this preferential search order can allow an attacker to make the loading process load the adversary's rogue library rather than the legitimate library. This attack can be leveraged with many different libraries and with many different loading processes. No forensic trails are left in the system's registry or file system that an incorrect library had been loaded.
