Security readout for executives and security teams
Plain-English summary
CVE-2022-40839 is a SQL injection issue in NdkAdvancedCustomizationFields v3.5.0. An unauthenticated attacker could use affected height and width inputs to extract database data. The main business risk is confidentiality loss from any exposed deployment using that version.
Executive priority
Treat this as a high-priority confidentiality risk for any confirmed deployment. Prioritize inventory first because the public metadata is sparse, then reduce exposure and follow vendor guidance.
Technical view
The CVE describes CWE-89 SQL injection in the height and width parameters of NdkAdvancedCustomizationFields v3.5.0. CVSS 3.1 is 7.5: network reachable, low complexity, no privileges, no user interaction, high confidentiality impact, no integrity or availability impact stated.
Likely exposure
Exposure is likely limited to deployments running NdkAdvancedCustomizationFields v3.5.0 with reachable affected parameters. The CVE metadata does not provide CPEs, vendor identity, or broader version ranges, so product inventory must be confirmed manually.
Exploitation context
The source bundle references a public GitHub PoC, so technical details are public. The CVE is not listed as KEV in the bundle, and no cited source confirms active exploitation.
Researcher notes
Evidence is concise but incomplete. The CVE states unauthenticated SQL injection and database exfiltration impact, but affected vendor/product fields are n/a and no official patch information is included in the provided bundle.
Mitigation direction
- Identify whether NdkAdvancedCustomizationFields v3.5.0 is deployed.
- Check vendor or project guidance for a fixed version or mitigation.
- Restrict public access to affected functionality until guidance is confirmed.
- Review database exposure and least-privilege permissions for the application account.
Validation and detection
- Confirm installed plugin/module name and version from application inventory.
- Map whether height and width inputs are reachable without authentication.
- Review application and database logs for suspicious parameter activity.
- Verify any vendor fix or workaround is applied in staging before production.
