Vulnerability from github – Published: 2022-05-13 01:34 – Updated: 2022-05-13 01:34A vulnerability in the DLL loading component of Cisco Advanced Malware Protection (AMP) for Endpoints on Windows could allow an authenticated, local attacker to disable system scanning services or take other actions to prevent detection of unauthorized intrusions. To exploit this vulnerability, the attacker would need to have administrative credentials on the Windows system. The vulnerability is due to the improper validation of resources loaded by a system process at run time. An attacker could exploit this vulnerability by crafting a malicious DLL file and placing it in a specific location on the targeted system. A successful exploit could allow the attacker to disable the targeted system's scanning services and ultimately prevent the system from being protected from further intrusion. There are no workarounds that address this vulnerability.

GHSA-J48Q-4C78-RHF9
Vulnerability from github – Published: 2026-03-31 23:31 – Updated: 2026-03-31 23:31Severity: HIGH
Summary
The Whirlpool hash implementation in openssl_encrypt/modules/registry/hash_registry.py at lines 570-589 uses glob patterns to find .so modules in site-packages and loads the first match via importlib without verifying module integrity.
Affected Code
for site_pkg in site.getsitepackages():
pattern = os.path.join(site_pkg, "whirlpool*py313*.so")
py313_modules = glob.glob(pattern)
if py313_modules:
module_path = py313_modules[0] # Takes first match
loader = ExtensionFileLoader("whirlpool", module_path)
spec = importlib.util.spec_from_file_location("whirlpool", module_path, loader=loader)
whirlpool_module = importlib.util.module_from_spec(spec)
spec.loader.exec_module(whirlpool_module)
Impact
The glob pattern "whirlpool*py313*.so" is broad and takes the first match without verifying:
- File hash/signature
- File ownership/permissions
- Whether it's a legitimate module
If an attacker can place a malicious .so file matching this pattern in any site-packages directory, it will be loaded and native code executed.
Recommended Fix
- Verify the module's integrity (hash or signature) before loading
- Use a specific filename rather than a glob pattern
- Check file permissions and ownership
Fix
Fixed in commit 963d0d1 on branch releases/1.4.x — added os.path.realpath() to resolve symlinks and validation that found .so files are within known site-packages directories before loading.

Mitigation
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
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
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
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
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.
