CVE-2025-11842

6.3 MEDIUM

📋 TL;DR

CVE-2025-11842 is a path traversal vulnerability in Shazwazza Smidge's Bundle Handler component that allows attackers to access files outside the intended directory by manipulating the Version parameter. This affects all systems running Smidge versions up to 4.5.1. Remote exploitation is possible, potentially exposing sensitive server files.

💻 Affected Systems

Products:
  • Shazwazza Smidge
Versions: All versions up to and including 4.5.1
Operating Systems: All platforms running Smidge
Default Config Vulnerable: ⚠️ Yes
Notes: All installations using the Bundle Handler component are vulnerable

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete server file system disclosure, including configuration files, credentials, and sensitive application data

🟠

Likely Case

Limited file disclosure from web-accessible directories, potentially exposing configuration files

🟢

If Mitigated

No impact with proper input validation and file system restrictions

🌐 Internet-Facing: HIGH - Remote exploitation possible without authentication
🏢 Internal Only: MEDIUM - Requires network access but no authentication

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

Requires specific knowledge of the Version parameter manipulation

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 4.6.0

Vendor Advisory: https://github.com/Shazwazza/Smidge/releases/tag/v4.6.0

Restart Required: No

Instructions:

1. Download Smidge 4.6.0 from GitHub releases. 2. Replace existing Smidge installation files. 3. Verify the update by checking the version.

🔧 Temporary Workarounds

Input Validation Filter

all

Implement server-side validation to reject path traversal sequences in the Version parameter

🧯 If You Can't Patch

  • Implement web application firewall (WAF) rules to block path traversal patterns
  • Restrict file system permissions for the Smidge application directory

🔍 How to Verify

Check if Vulnerable:

Check Smidge version in application configuration or package manager

Check Version:

Check package.json or assembly version for Smidge

Verify Fix Applied:

Confirm Smidge version is 4.6.0 or higher
