CVE-2024-33617

5.9 MEDIUM

📋 TL;DR

This vulnerability in Intel QAT Engine for OpenSSL allows attackers to potentially disclose sensitive information via network access. It affects systems using Intel QAT Engine versions before v1.6.1 for cryptographic acceleration. The information disclosure could expose cryptographic keys or other sensitive data processed by the engine.

💻 Affected Systems

Products:
  • Intel QAT Engine for OpenSSL
Versions: All versions before v1.6.1
Operating Systems: Linux, Windows, Other platforms supporting Intel QAT
Default Config Vulnerable: ⚠️ Yes
Notes: Only affects systems with Intel QAT hardware acceleration enabled and using vulnerable QAT Engine software.

⚠️ 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

Complete compromise of cryptographic keys leading to decryption of sensitive communications and data breaches.

🟠

Likely Case

Partial information disclosure of cryptographic material or internal memory contents via network requests.

🟢

If Mitigated

No impact if patched or if QAT Engine is not exposed to untrusted networks.

🌐 Internet-Facing: MEDIUM - Requires network access but exploit complexity is moderate.
🏢 Internal Only: LOW - Internal systems typically have controlled network access reducing exposure.

🎯 Exploit Status

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

Exploitation requires network access to systems using vulnerable QAT Engine, but specific exploit details are not publicly documented.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: v1.6.1

Vendor Advisory: https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-01177.html

Restart Required: Yes

Instructions:

1. Download Intel QAT Engine v1.6.1 or later from Intel's website. 2. Stop services using QAT Engine. 3. Install the updated version. 4. Restart affected services and verify functionality.

🔧 Temporary Workarounds

Disable QAT Engine

all

Temporarily disable Intel QAT Engine acceleration to mitigate vulnerability

# Edit OpenSSL configuration to remove QAT Engine
# Comment out or remove 'engine=qat' lines in openssl.cnf

Network Segmentation

linux

Restrict network access to systems using QAT Engine

# Use firewall rules to limit access
iptables -A INPUT -p tcp --dport [QAT_PORT] -j DROP

🧯 If You Can't Patch

  • Implement strict network access controls to limit exposure to trusted sources only
  • Monitor for unusual network traffic patterns to/from systems using QAT Engine

🔍 How to Verify

Check if Vulnerable:

Check QAT Engine version: openssl engine -t qat

Check Version:

openssl engine -t qat

Verify Fix Applied:

Verify version is v1.6.1 or later: openssl engine -t qat | grep -i version

📡 Detection & Monitoring

Log Indicators:

  • Unusual OpenSSL/QAT Engine error messages
  • Failed cryptographic operations
  • Unexpected process crashes in QAT-related services

Network Indicators:

  • Unusual traffic patterns to/from QAT-enabled systems
  • Multiple failed connection attempts to QAT services

SIEM Query:

source="*qat*" OR source="*openssl*" AND (error OR fail OR crash)
