Security readout for executives and security teams
Plain-English summary
A logged-in attacker could place malicious script or HTML into a Liferay Object field label. When another user opens the affected edit object details page, that content may run in their browser. This can expose limited data or alter page actions, but the CVSS scope indicates no direct availability impact.
Executive priority
Prioritize remediation in normal vulnerability cycles, faster where untrusted or many low-privilege users can edit objects. The business risk is browser-side compromise of Liferay users, especially administrators, rather than server takeover.
Technical view
CVE-2022-42115 is a stored cross-site scripting issue in Liferay Portal 7.4.3.4 through 7.4.3.36, in the Object module edit object details page. The Label text field was the injection point. CVSS 3.1 is 5.4: network reachable, low complexity, low privileges required, and user interaction required.
Likely exposure
Organizations running Liferay Portal 7.4.3.4 through 7.4.3.36 and using the Object module are the likely exposure group. Exposure depends on who can edit object field labels and who later views the affected details page.
Exploitation context
The provided sources do not show CISA KEV listing or active exploitation. Exploitation requires an attacker with some authenticated access and a victim user opening the affected page. Treat it as a credible internal or low-privilege account abuse risk, not a wormable perimeter compromise.
Researcher notes
The source bundle identifies CWE-79 and CVSS vector CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N. Affected metadata is incomplete in the bundle, but the description names Liferay Portal 7.4.3.4 through 7.4.3.36. No exploit status or fixed version is provided here.
Mitigation direction
- Check Liferay's official advisory for the supported fixed version or patch guidance.
- Upgrade affected Liferay Portal instances according to vendor guidance.
- Restrict Object module field-label editing to trusted administrators.
- Review existing object field labels for unexpected HTML or script-like content.
- Use monitoring to flag suspicious changes to object definitions.
Validation and detection
- Inventory Liferay Portal versions and identify 7.4.3.4 through 7.4.3.36 instances.
- Confirm whether the Object module is enabled and used.
- Review permissions for users allowed to edit object field labels.
- Inspect object field labels for unauthorized markup or suspicious values.
- Verify remediation against Liferay's advisory after applying updates.

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.
