CVE-2025-14413

7.8 HIGH

📋 TL;DR

This vulnerability allows remote attackers to execute arbitrary code on Soda PDF Desktop by tricking users into opening malicious CBZ files. Attackers can exploit directory traversal flaws to write files outside intended directories, leading to code execution with the victim's privileges. All users of vulnerable Soda PDF Desktop versions are affected.

💻 Affected Systems

Products:
  • Soda PDF Desktop
Versions: Versions prior to the vendor patch (specific version unknown from provided data)
Operating Systems: Windows
Default Config Vulnerable: ⚠️ Yes
Notes: Requires user interaction to open malicious CBZ file. All default installations are vulnerable.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system compromise via remote code execution, allowing attackers to install malware, steal data, or pivot to other systems.

🟠

Likely Case

Malware installation leading to data theft, ransomware deployment, or credential harvesting from the compromised user account.

🟢

If Mitigated

Limited impact if proper application sandboxing, file integrity monitoring, and user privilege restrictions are in place.

🌐 Internet-Facing: MEDIUM
🏢 Internal Only: HIGH

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: LIKELY
Unauthenticated Exploit: ⚠️ Yes
Complexity: LOW

Exploitation requires user interaction but is technically simple once malicious CBZ file is crafted. ZDI has confirmed the vulnerability.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Unknown from provided references - check vendor advisory

Vendor Advisory: Not provided in references

Restart Required: Yes

Instructions:

1. Check for updates in Soda PDF Desktop
2. Install latest version from official vendor source
3. Restart application and system if required

🔧 Temporary Workarounds

Block CBZ file extensions

windows

Prevent Soda PDF from opening CBZ files via group policy or application restrictions

Application sandboxing

windows

Run Soda PDF in restricted user context with minimal privileges

🧯 If You Can't Patch

  • Disable Soda PDF Desktop entirely and use alternative PDF software
  • Implement application whitelisting to prevent unauthorized code execution

🔍 How to Verify

Check if Vulnerable:

Check Soda PDF version against vendor's patched version. If version is older than patched release, system is vulnerable.

Check Version:

Open Soda PDF → Help → About (or check in application settings)

Verify Fix Applied:

Verify Soda PDF is updated to latest version and attempt to reproduce with test CBZ file (in isolated environment).

📡 Detection & Monitoring

Log Indicators:

  • Unusual file writes outside expected directories
  • Soda PDF process spawning unexpected child processes
  • CBZ file processing errors

Network Indicators:

  • Downloads of CBZ files from untrusted sources
  • Outbound connections from Soda PDF process to unknown IPs

SIEM Query:

Process creation where parent_process contains 'sodapdf' AND (process_name contains 'cmd' OR process_name contains 'powershell' OR process_name contains 'wscript')
