CVE-2023-42496
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 · uneditedReflected cross-site scripting (XSS) vulnerability on the add assignees to a role page in Liferay Portal 7.3.3 through 7.4.3.97, and Liferay DXP 2023.Q3 before patch 6, 7.4 GA through update 92, and 7.3 before update 34 allows remote attackers to inject arbitrary web script or HTML via the _com_liferay_roles_admin_web_portlet_RolesAdminPortlet_tabs2 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 in Liferay Portal/DXP RolesAdminPortlet where the _com_liferay_roles_admin_web_portlet_RolesAdminPortlet_tabs2 parameter is not properly sanitized before being rendered back to users, allowing injection of arbitrary JavaScript/HTML.

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 installed Lifereray Portal/DXP versionLocate the liferay-version.properties file in the Liferay installation directory (typically at [LIFERAY_HOME]/portal-impl/src/com/lifer/portal/util/lifer-version.properties) or check the OSGi console for the portal bundle versionAffected if The installed version falls within >= 7.3.3 and < 7.4.3.98 for Liferay Portal, or equals 7.3 or 7.4 for Liferay DXP
-
Confirm RolesAdminPortlet deploymentCheck the deployed portlets in the Liferay control panel or inspect the web.xml/portlet.xml for the presence of 'roles-admin-web' portlet bundleAffected if The RolesAdminPortlet is deployed and accessible in the environment
-
Verify authenticated access to Roles administrationConfirm whether any portal user has access to the Roles section in the control panel (Control Panel > Users > Roles). The XSS requires an authenticated session to trigger the vulnerable parameterAffected if Users with access to the RolesAdminPortlet exist or can be created
-
Inspect HTTP request handling for tabs2 parameterReview server configuration or proxy logs to observe how the _com_lifer_roles_admin_web_portlet_RolesAdminPortlet_tabs2 parameter is processed and whether output encoding is appliedAffected if The parameter value is reflected in the response without proper encoding or sanitization
A user is affected if they run Liferay Portal 7.3.3 through 7.4.3.97 or Liferay DXP 7.3 or 7.4, and the RolesAdminPortlet is accessible to authenticated users who could be tricked into clicking a crafted link containing the malicious tabs2 parameter.

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 · scoped7.4.3.98
Apply Liferay's vendor patches (update 34 for 7.3, update 92 for 7.4, patch 6 for 2023.Q3) or upgrade to a patched version. Implement proper output encoding on the tabs2 parameter before rendering.
Liferay Portal 7.4.3.98+ (or DXP 7.4 update 93+, DXP 7.3 update 34+, or Hotfix Patch 6 for 2023.Q3)
- 1. Identify the exact Liferay product and version currently running (Portal or DXP, and specific update version)
- 2. For Liferay Portal 7.3.3 through 7.4.3.97: Upgrade to Liferay Portal 7.4.3.98 or later
- 3. For Liferay DXP 7.4 GA through update 92: Upgrade to Liferay DXP 7.4 update 93 or later
- 4. For Liferay DXP 7.3 before update 34: Upgrade to Liferay DXP 7.3 update 34 or later
- 5. For Liferay DXP 2023.Q3: Apply Hotfix Patch 6 or later
- 6. After upgrade/patching, verify the _com_liferay_roles_admin_web_portlet_RolesAdminPortlet_tabs2 parameter is properly sanitized and no longer vulnerable
- 7. Test the Roles Admin Portlet add assignees functionality to confirm the XSS vulnerability is resolved
