Security readout for executives and security teams
Plain-English summary
This is a stored or reflected XSS risk in Liferay’s Portal Search Custom Facet widget. An attacker can place script or HTML into the Custom Parameter Name field, causing browser-side code execution when a user views the affected page. Business impact is mainly session, data, and trust risk, not server takeover.
Executive priority
Handle as a planned but timely remediation for exposed Liferay sites. It is not described as actively exploited, but XSS in enterprise portals can support account misuse, phishing, or data exposure if left unpatched.
Technical view
CVE-2022-28979 is CWE-79 in Liferay Portal 7.1.0 through 7.4.2 and specified Liferay DXP 7.1, 7.2, and 7.3 releases before named fix packs or service pack. CVSS 3.1 is 6.1: network reachable, low complexity, no privileges, user interaction required, changed scope, low confidentiality and integrity impact.
Likely exposure
Exposure is likely where affected Liferay Portal or DXP versions use the Portal Search Custom Facet widget, especially on pages reachable by untrusted users or administrators reviewing user-controlled search configuration.
Exploitation context
The provided sources do not report active exploitation, and the CVE is not marked KEV. Exploitation requires crafted script or HTML in the Custom Parameter Name field and user interaction with the affected rendered content.
Researcher notes
The bundle identifies the sink as the Custom Parameter Name text field in the Custom Facet widget. Evidence is sufficient for affected version triage and patch direction, but it does not include exploit telemetry, detailed root cause, or compensating controls beyond vendor fixes.
Mitigation direction
- Apply the relevant Liferay fix pack, service pack, or later corrected release.
- Prioritize public-facing or externally accessible Liferay search pages.
- Restrict who can configure Portal Search Custom Facet widgets.
- Follow Liferay advisory and LPE-17381 guidance for version-specific remediation.
Validation and detection
- Inventory Liferay Portal and DXP versions against the affected ranges.
- Check whether Portal Search Custom Facet widgets are deployed.
- Review Custom Parameter Name values for unexpected script or HTML content.
- Confirm fixed versions or fix packs are installed after remediation.
- Retest affected pages for safe rendering after update.

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.
