CVE-2022-42118
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA Cross-site scripting (XSS) vulnerability in the Portal Search module in Liferay Portal 7.1.0 through 7.4.2, and Liferay DXP 7.1 before fix pack 27, 7.2 before fix pack 15, and 7.3 before service pack 3 allows remote attackers to inject arbitrary web script or HTML via the `tag` parameter.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceReflected XSS vulnerability in Liferay's Portal Search module where the `tag` parameter is not properly sanitized, allowing remote attackers to inject arbitrary web script or HTML via crafted URLs. The vulnerability affects both Liferay Portal (7.1.0-7.4.2) and Liferay DXP (7.1 before fp27, 7.2 before fp15, 7.3 before sp3).

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the installed Lifera Portal or DXP versionCheck the product version in the Liferay control panel (Control Panel > Configuration > System Information) or inspect the welcome page footer. Alternatively, check the WAR file or portal.properties for the 'liferaay.version' property.Affected if The version falls within 7.1.0 to 7.4.2 for Portal, or is DXP 7.1 before fp27, 7.2 before fp15, or 7.3 before sp3.
-
Confirm the search module is accessibleVerify that the Liferay search functionality is enabled and accessible. Typically found at endpoints like /c/portal/search or /search depending on configuration. Check if the search portlet or widget is deployed.Affected if The search module is active and accessible without authentication restrictions.
-
Verify fix pack or patch applicationCheck the installed fix packs by navigating to Control Panel > Configuration > System Information > Patch Info. Compare the installed fix pack level against the required fixes (fp27 for DXP 7.1, fp15 for DXP 7.2, sp3 for DXP 7.3).Affected if The installed fix pack level is below the required threshold for the respective version.
You are affected if your Liferay Portal version is between 7.1.0 and 7.4.2, or your DXP version is 7.1 before fp27, 7.2 before fp15, or 7.3 before sp3, and the search module is accessible without having applied the corresponding vendor fix pack.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedApply the vendor-supplied fix packs (fp27 for DXP 7.1, fp15 for DXP 7.2, sp3 for DXP 7.3, or appropriate patch for Portal versions) and implement output encoding for the tag parameter in the search module.
Lifer Portal 7.4.3+ or appropriate DXP fix pack (FP27 for 7.1, FP15 for 7.2, SP3 for 7.3)
- 1. Identify your current Lifer Portal or DXP version using the Lifer Server Administration console or the control panel.
- 2. For Lifer Portal 7.1.0 - 7.4.x users: Upgrade to Lifer Portal 7.4.3 or later, as this version contains the fix for the XSS vulnerability in the Portal Search module.
- 3. For Lifer DXP 7.1 users: Apply fix pack 27 or later to address the vulnerability.
- 4. For Lifer DXP 7.2 users: Apply fix pack 15 or later to address the vulnerability.
- 5. For Lifer DXP 7.3 users: Apply service pack 3 or later to address the vulnerability.
- 6. After applying the fix, verify the patch was successfully installed by checking the Lifer Marketplace or Server Administration panel for the updated version number.
- 7. Test the Portal Search functionality with the tag parameter to confirm the XSS vulnerability is remediated.
