CVE-2025-20003

8.2 HIGH

📋 TL;DR

This vulnerability in Intel Graphics Driver installers allows authenticated local users to exploit improper link resolution (symlink attacks) to escalate privileges. Attackers could potentially gain SYSTEM/root-level access by manipulating symbolic links during installation processes. This affects systems with vulnerable Intel Graphics Driver versions installed.

💻 Affected Systems

Products:
  • Intel Graphics Driver Installers
Versions: Specific versions not detailed in advisory; refer to Intel SA-01259 for exact affected versions
Operating Systems: Windows, Linux (potentially)
Default Config Vulnerable: ⚠️ Yes
Notes: Requires local authenticated user access. Vulnerability exists in the installer software, not necessarily the driver runtime.

⚠️ 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).

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/SYSTEM privileges, allowing complete control over the affected system, data theft, persistence mechanisms, and lateral movement capabilities.

🟠

Likely Case

Local privilege escalation from standard user to administrator/SYSTEM privileges, enabling installation of malware, disabling security controls, or accessing protected data.

🟢

If Mitigated

Limited impact with proper user access controls, but still presents risk in multi-user environments or where users have local access to vulnerable systems.

🌐 Internet-Facing: LOW - Requires local authenticated access, not directly exploitable over network.
🏢 Internal Only: HIGH - Significant risk in enterprise environments where users have local access to workstations/servers with vulnerable drivers.

🎯 Exploit Status

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

Requires local authenticated access and ability to create symbolic links. Exploitation likely involves timing attacks during installation processes.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Refer to Intel SA-01259 for specific patched versions

Vendor Advisory: https://intel.com/content/www/us/en/security-center/advisory/intel-sa-01259.html

Restart Required: Yes

Instructions:

1. Visit Intel Security Advisory SA-01259. 2. Identify affected driver versions for your hardware. 3. Download and install updated graphics drivers from Intel Download Center. 4. Restart system after installation.

🔧 Temporary Workarounds

Restrict Symbolic Link Creation

all

Prevent non-administrative users from creating symbolic links to mitigate exploitation vectors

Windows: Configure security policy to restrict symlink creation via Group Policy
Linux: Set kernel.symlink_restrictions or use filesystem ACLs

Least Privilege User Accounts

all

Ensure users operate with minimal necessary privileges to limit impact

🧯 If You Can't Patch

  • Implement strict access controls to limit local user access to vulnerable systems
  • Monitor for suspicious file system activities and symlink creation attempts

🔍 How to Verify

Check if Vulnerable:

Check Intel Graphics Driver version against affected versions listed in Intel SA-01259 advisory

Check Version:

Windows: dxdiag (Display tab) or Device Manager > Display adapters > Properties > Driver. Linux: glxinfo | grep 'OpenGL version' or check package manager

Verify Fix Applied:

Verify installed Intel Graphics Driver version matches or exceeds patched versions from advisory

📡 Detection & Monitoring

Log Indicators:

  • Unusual symlink creation events
  • Failed privilege escalation attempts
  • Suspicious installer process activities

Network Indicators:

  • Not network exploitable - focus on host-based detection

SIEM Query:

Windows: EventID 4688 with process name containing Intel installer components AND target path anomalies. Linux: auditd events for symlink() syscalls with suspicious paths
