CVE-2025-54519

7.3 HIGH

📋 TL;DR

A DLL hijacking vulnerability in AMD Doc Nav software allows local attackers to escalate privileges by placing malicious DLLs in directories searched by the application. This could lead to arbitrary code execution with elevated privileges. Users running vulnerable versions of AMD Doc Nav on Windows systems are affected.

💻 Affected Systems

Products:
  • AMD Doc Nav
Versions: All versions prior to the fix
Operating Systems: Windows
Default Config Vulnerable: ⚠️ Yes
Notes: Requires local access to the system. The vulnerability exists in how Doc Nav searches for and loads DLLs.

⚠️ 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).

🔒 Custom verification scripts are available for registered users. Sign up free to download automated test scripts.

Recommended Actions:
  1. Review the CVE details at NVD
  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Full system compromise with administrative privileges, enabling installation of persistent malware, data theft, and complete control over the affected system.

🟠

Likely Case

Local privilege escalation allowing attackers to execute arbitrary code with higher privileges than their current user account, potentially leading to lateral movement within the network.

🟢

If Mitigated

Limited impact if proper application whitelisting, DLL search path hardening, and least privilege principles are implemented.

🌐 Internet-Facing: LOW - This is a local attack vector requiring initial access to the system.
🏢 Internal Only: HIGH - Once an attacker gains initial access (even as a standard user), they can exploit this to escalate privileges and move laterally.

🎯 Exploit Status

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

DLL hijacking is a well-understood attack technique. Exploitation requires the attacker to place a malicious DLL in a directory that the application searches before the legitimate DLL location.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Check AMD advisory for specific fixed version

Vendor Advisory: https://www.amd.com/en/resources/product-security/bulletin/AMD-SB-8013.html

Restart Required: Yes

Instructions:

1. Visit the AMD security advisory URL. 2. Download the latest version of AMD Doc Nav. 3. Install the update following AMD's instructions. 4. Restart the system if prompted.

🔧 Temporary Workarounds

Restrict DLL search paths

windows

Use application control policies to restrict where Doc Nav can load DLLs from

Use Windows AppLocker or similar to restrict DLL loading to trusted directories

Remove unnecessary permissions

windows

Remove write permissions from directories where Doc Nav searches for DLLs

icacls "C:\Program Files\AMD\Doc Nav" /deny Users:(OI)(CI)W

🧯 If You Can't Patch

  • Uninstall AMD Doc Nav if not required for business operations
  • Implement strict application whitelisting to prevent unauthorized DLL loading

🔍 How to Verify

Check if Vulnerable:

Check AMD Doc Nav version against the advisory. If running an older version, assume vulnerable.

Check Version:

Check Doc Nav 'About' section or examine installed programs in Control Panel

Verify Fix Applied:

Verify AMD Doc Nav has been updated to the version specified in the AMD advisory

📡 Detection & Monitoring

Log Indicators:

  • Windows Event Logs showing DLL loading from unusual paths
  • Process Monitor logs showing Doc Nav searching for DLLs in user-writable directories

Network Indicators:

  • Unusual outbound connections from Doc Nav process after exploitation

SIEM Query:

Process Creation where Image ends with 'DocNav.exe' AND (CommandLine contains *.dll OR ParentImage contains suspicious process)
