CVE-2025-22217

8.6 HIGH

📋 TL;DR

CVE-2025-22217 is an unauthenticated blind SQL injection vulnerability in Avi Load Balancer that allows attackers with network access to execute arbitrary SQL queries against the database. This affects VMware Avi Load Balancer deployments, potentially exposing sensitive configuration data and credentials. Organizations using vulnerable versions should patch immediately.

💻 Affected Systems

Products:
  • VMware Avi Load Balancer
Versions: Specific versions not provided in advisory - check vendor documentation
Operating Systems: Linux-based appliance
Default Config Vulnerable: ⚠️ Yes
Notes: All deployments with vulnerable versions are affected regardless of configuration.

⚠️ 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

Complete database compromise leading to credential theft, configuration manipulation, and potential lateral movement to connected systems.

🟠

Likely Case

Extraction of sensitive configuration data, administrative credentials, and potential service disruption through database manipulation.

🟢

If Mitigated

Limited information disclosure if database permissions are properly restricted, but still represents significant security risk.

🌐 Internet-Facing: HIGH - Unauthenticated nature means any internet-exposed vulnerable instance can be attacked without credentials.
🏢 Internal Only: HIGH - Even internally, any user with network access can exploit this without authentication.

🎯 Exploit Status

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

Unauthenticated access lowers exploitation barrier significantly. Blind SQL injection requires more sophisticated exploitation but is well-understood.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Check Broadcom/VMware advisory for specific patched versions

Vendor Advisory: https://support.broadcom.com/web/ecx/support-content-notification/-/external/content/SecurityAdvisories/0/25346

Restart Required: No

Instructions:

1. Review Broadcom advisory for affected versions. 2. Download and apply the appropriate patch from VMware/Broadcom. 3. Verify patch application and test functionality.

🔧 Temporary Workarounds

Network Segmentation

all

Restrict network access to Avi Load Balancer management interfaces to authorized administrative networks only.

Web Application Firewall

all

Deploy WAF with SQL injection protection rules in front of vulnerable interfaces.

🧯 If You Can't Patch

  • Implement strict network access controls to limit exposure to trusted sources only
  • Deploy intrusion detection/prevention systems with SQL injection signatures

🔍 How to Verify

Check if Vulnerable:

Check Avi Controller version against patched versions in vendor advisory

Check Version:

ssh admin@avi-controller show version

Verify Fix Applied:

Verify version is updated to patched release and test SQL injection attempts are blocked

📡 Detection & Monitoring

Log Indicators:

  • Unusual SQL query patterns in application logs
  • Multiple failed authentication attempts from single source
  • Database error messages containing SQL syntax

Network Indicators:

  • Unusual SQL keywords in HTTP requests to management interfaces
  • Repeated requests with SQL injection patterns
  • Traffic to database ports from unexpected sources

SIEM Query:

source="avi-logs" AND ("sql" OR "database" OR "injection") AND ("error" OR "failed" OR "malformed")
