CVE-2025-50330 Overview
CVE-2025-50330 affects ZipGenius Team ZipGenius version 6.3.2.3116 and earlier. The vulnerability allows a remote attacker to escalate privileges and execute arbitrary code through the zipgenius.exe binary. ZipGenius is a Windows file archiver used to compress and decompress multiple archive formats.
The flaw enables attackers to gain elevated privileges on the target system after successful exploitation. Public references indicate the issue resides in how zipgenius.exe handles operations that should require higher privilege boundaries. Users running vulnerable installations should treat the software as untrusted until an updated release is available.
Critical Impact
Remote attackers can escalate privileges and execute arbitrary code on systems running ZipGenius 6.3.2.3116 or earlier through the zipgenius.exe executable.
Affected Products
- ZipGenius Team ZipGenius v6.3.2.3116
- ZipGenius Team ZipGenius versions prior to 6.3.2.3116
- Windows systems with zipgenius.exe installed

Technical Details for CVE-2025-50330
Vulnerability Analysis
CVE-2025-50330 is a privilege escalation and arbitrary code execution flaw in the ZipGenius archive utility. The vulnerability is triggered through the zipgenius.exe binary shipped with version 6.3.2.3116 and earlier. Successful exploitation lets a remote attacker run code in the context of the affected application and elevate privileges on the host.
ZipGenius handles multiple archive formats and integrates with Windows Explorer. Archive utilities frequently process untrusted files from email attachments, downloads, and network shares. This exposure surface allows attacker-controlled input to reach vulnerable code paths without direct interactive access to the machine.
The NVD entry does not specify the exact root cause class, and no CWE has been assigned. Additional technical detail is published in the GitHub CVE-2025-50330 reference.
Root Cause
The root cause is located in zipgenius.exe, according to the vendor advisory summary. The application fails to enforce appropriate privilege boundaries during operations that a remote attacker can influence. This weakness allows an attacker to combine code execution with privilege elevation in a single exploitation chain.
Attack Vector
The vulnerability is reachable remotely. An attacker can deliver a crafted archive or trigger the vulnerable path in zipgenius.exe through standard workflows such as opening or extracting attacker-supplied archives. Once triggered, the process executes arbitrary code and escalates privileges on the target Windows host.
No public proof-of-concept exploit is confirmed by the NVD entry, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog at the time of publication. Refer to the ZipGenius download page for available releases.
Detection Methods for CVE-2025-50330
Indicators of Compromise
- Execution of zipgenius.exe followed by unexpected child processes such as cmd.exe, powershell.exe, or rundll32.exe
- Creation of files or registry entries under privileged locations following archive extraction activity
- Network connections originating from zipgenius.exe to untrusted external hosts
- Presence of ZipGenius version 6.3.2.3116 or earlier on managed endpoints
Detection Strategies
- Inventory endpoints for installed ZipGenius versions using software asset management or endpoint telemetry
- Alert on zipgenius.exe spawning interpreter or scripting processes, which is atypical behavior for an archive utility
- Monitor for privilege elevation events immediately following archive extraction operations
- Correlate archive file writes from email or browser download directories with subsequent execution of zipgenius.exe
Monitoring Recommendations
- Enable process creation logging (Windows Event ID 4688 or Sysmon Event ID 1) with command-line auditing across endpoints
- Track file system events in user download and temp directories where archives are commonly extracted
- Review authentication and token elevation events that follow ZipGenius activity
- Feed archive utility telemetry into a centralized log platform for retroactive threat hunting
How to Mitigate CVE-2025-50330
Immediate Actions Required
- Identify all endpoints running ZipGenius 6.3.2.3116 or earlier and prioritize remediation
- Restrict execution of zipgenius.exe through application control policies until a fixed version is confirmed
- Instruct users to avoid opening archives from untrusted senders or unknown sources
- Route unknown archive files through a sandboxed analysis environment before user access
Patch Information
No vendor patch is referenced in the NVD entry at the time of publication. Monitor the ZipGenius download page for updated releases addressing CVE-2025-50330. Track the public reference on GitHub for additional technical updates.
Workarounds
- Uninstall ZipGenius and replace it with an actively maintained archive utility until a fix is available
- Apply Windows AppLocker or Windows Defender Application Control rules to block zipgenius.exe from executing
- Remove ZipGenius file association handlers so archives do not open in the vulnerable application by default
- Enforce least privilege on user accounts to reduce the impact of successful privilege escalation attempts
# Example AppLocker rule concept to block zipgenius.exe execution
# Create a Path Rule under Executable Rules:
# Action: Deny
# User or group: Everyone
# Path: %PROGRAMFILES%\ZipGenius 6\zipgenius.exe
# Apply via Group Policy: Computer Configuration >
# Windows Settings > Security Settings > Application Control Policies > AppLocker
