Security readout for executives and security teams
Plain-English summary
CVE-2022-42122 is a critical SQL injection issue in Liferay’s Friendly Url module. An unauthenticated network attacker could submit crafted data in a friendly URL title field and run arbitrary SQL. For an exposed Liferay portal, this could threaten data confidentiality, integrity, and availability.
Executive priority
High priority. The vulnerability has critical severity and can affect core portal data. If the organization uses the named Liferay versions, confirm exposure and follow Liferay remediation guidance promptly, starting with internet-facing systems.
Technical view
The CVE describes CWE-89 SQL injection in Liferay Portal 7.3.7 and Liferay DXP 7.3 fix pack 2 through update 4. The vulnerable input is the `title` field of a friendly URL. CVSS 3.1 is 9.8: network attack vector, low complexity, no privileges, no user interaction, high CIA impact.
Likely exposure
Organizations running Liferay Portal 7.3.7 or Liferay DXP 7.3 fix pack 2 through update 4 may be exposed, especially if the portal is internet-facing. The source bundle does not provide CPEs or broader affected-version details.
Exploitation context
The CVE indicates remote unauthenticated exploitability by crafted input, but the provided sources do not state active exploitation. It is not listed as KEV in the provided bundle. Treat internet-facing affected Liferay portals as high-priority until vendor guidance is confirmed.
Researcher notes
Public details in the bundle are limited to affected versions, module, parameter, CWE, and CVSS. Do not assume additional affected versions or exploit availability. The Liferay advisory and LPE-17520 issue should be treated as the authoritative sources for remediation specifics.
Mitigation direction
- Check Liferay’s advisory for fixed versions or update guidance.
- Prioritize remediation for internet-facing Liferay Portal or DXP instances.
- Restrict unnecessary public access to affected portal functions where feasible.
- Increase monitoring for abnormal database errors or portal behavior.
- Back up critical portal and database data before remediation.
Validation and detection
- Inventory Liferay Portal and DXP deployments and exact versions.
- Identify any Liferay Portal 7.3.7 instances.
- Identify any Liferay DXP 7.3 fix pack 2 through update 4 instances.
- Review Liferay advisory and issue tracker for official remediation status.
- Check security logs for suspicious friendly URL title submissions or SQL errors.
