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
Pipewire: pipewire: sandbox escape and arbitrary code execution via malicious library loading
Summary
A flaw was found in PipeWire, a multimedia server. This vulnerability allows an attacker to escape sandboxed applications, such as Flatpak, by exploiting PipeWire's PulseAudio compatibility layer. An attacker with minimal permissions within a sandboxed environment can load a malicious library, leading to arbitrary code execution outside the sandbox and potential compromise of the user's system.

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.

Title
NoMachine Uncontrolled Search Path Element Local Privilege Escalation Vulnerability
Summary
NoMachine Uncontrolled Search Path Element Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of NoMachine. 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 NoMachine Device Server. The product loads a library from an unsecured location. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM. Was ZDI-CAN-28494.

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.
