Security readout for executives and security teams
Plain-English summary
This is a cross-site scripting issue in Liferay’s Portal Search Sort widget. An attacker with low privileges could inject script or HTML that runs when another user interacts with a crafted page or payload. Business impact is mainly account misuse, data exposure, and portal trust damage, not server takeover.
Executive priority
Treat as a scheduled but prompt remediation for affected portals, especially internet-facing ones. The issue is medium severity and requires user interaction, but XSS in a business portal can still affect sessions, data, and user trust.
Technical view
CVE-2022-42112 is CWE-79 XSS affecting Liferay Portal 7.2.0 through 7.4.3.24, and Liferay DXP 7.2 before fix pack 19, 7.3 before update 5, and 7.4 before update 25. CVSS 3.1 is 5.4: network reachable, low complexity, low privileges, user interaction required, changed scope, low confidentiality and integrity impact.
Likely exposure
Exposure is most likely for organizations running affected Liferay Portal or DXP versions with the Portal Search module’s Sort widget available to authenticated users, especially on externally reachable portals.
Exploitation context
The source bundle does not show CISA KEV listing or cited evidence of active exploitation. The CVSS vector indicates exploitation requires attacker privileges and victim interaction, limiting urgency compared with unauthenticated XSS but still relevant for public portals.
Researcher notes
Evidence supports stored or reflected script injection risk in the Portal Search Sort widget, but the bundle does not specify payload handling, affected endpoints, or proof-of-concept details. Avoid assuming exploit maturity beyond the CVSS and advisory data.
Mitigation direction
- Upgrade Liferay Portal and DXP beyond the affected versions named in the advisory.
- For DXP 7.2, apply fix pack 19 or later per vendor guidance.
- For DXP 7.3, apply update 5 or later per vendor guidance.
- For DXP 7.4, apply update 25 or later per vendor guidance.
- Review Liferay’s advisory for exact supported remediation paths.
Validation and detection
- Inventory Liferay Portal and DXP versions across public and internal portals.
- Confirm whether Portal Search and the Sort widget are enabled.
- Check patch, fix pack, or update level against the affected version ranges.
- Review application security logs for suspicious script or HTML injection attempts.
- Validate remediation in a test environment before production rollout.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
