A SQL injection vulnerability in the Fragment module in Liferay Portal 7.3.3 through 7.4.3.16, and Liferay DXP 7.3 before update 4, and 7.4 before update 17 allows attackers to execute arbitrary SQL commands via a PortletPreferences' `namespace` attribute.
Security readout for executives and security teams
Plain-English summary
CVE-2022-42120 is a critical SQL injection flaw in Liferay’s Fragment module. An unauthenticated remote attacker could potentially run arbitrary database commands, risking data theft, data alteration, and service disruption. Organizations running affected Liferay Portal or DXP versions should prioritize verification and upgrade planning.
Executive priority
Treat as urgent for any internet-facing or business-critical Liferay deployment. The issue can affect confidentiality, integrity, and availability, and vendor version ranges identify clear remediation targets.
Technical view
The vulnerability is CWE-89 SQL injection via the PortletPreferences `namespace` attribute in the Fragment module. Affected versions are Liferay Portal 7.3.3 through 7.4.3.16, Liferay DXP 7.3 before update 4, and Liferay DXP 7.4 before update 17. CVSS v3.1 is 9.8: network-accessible, low complexity, no privileges, no user interaction.
Likely exposure
Exposure is most likely where affected Liferay Portal or DXP instances are reachable over a network, especially internet-facing portals. The source bundle does not identify specific configurations beyond the affected versions and module context.
Exploitation context
No CISA KEV listing is reported in the source bundle, and the provided sources do not state active exploitation. The CVSS vector indicates exploitation does not require authentication or user interaction, increasing urgency for exposed systems.
Researcher notes
Analysis is limited to the CVE description, Liferay advisory, and Liferay issue reference provided. The bundle does not include proof-of-concept details, observed exploitation, or compensating controls beyond updating outside affected ranges and checking vendor guidance.
Mitigation direction
Inventory all Liferay Portal and DXP instances and record exact versions.
Upgrade Liferay Portal beyond 7.4.3.16 if affected.
Update Liferay DXP 7.3 to update 4 or later.
Update Liferay DXP 7.4 to update 17 or later.
Review Liferay’s advisory and issue record for current vendor guidance.
Restrict network exposure to Liferay instances where business allows.
Validation and detection
Confirm whether the Fragment module is present in deployed Liferay instances.
Compare deployed versions against the affected version ranges.
Check change records for Liferay DXP update 4 or update 17 application.
Review application and database logs for unusual SQL errors or unexpected data changes.
Monitor vendor advisory pages for revised affected versions or remediation guidance.

CWE-89: Database access and collection lookup
Injection into data stores can inform collection, data access, and exfiltration detection reviews. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
The CVE wording references database injection or access, so collection and exfiltration review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
