Security readout for executives and security teams
Plain-English summary
CVE-2021-35463 is a cross-site scripting flaw in Liferay Portal 7.4.0. A remote attacker could inject script or HTML through the management toolbar search keywords parameter. Business impact depends on who can reach that toolbar and what privileges their browser session has.
Executive priority
Handle as a medium-priority web application risk unless the affected toolbar is exposed to untrusted users or privileged sessions. Escalate if production portals hold sensitive data or administrative users frequently access the vulnerable interface.
Technical view
The source describes XSS in the Frontend Taglib module of Liferay Portal 7.4.0, specifically via the keywords parameter in management toolbar search. No CVSS, CWE, affected CPEs, patch version, or workaround details are included in the provided bundle.
Likely exposure
Exposure is likely limited to organizations running Liferay Portal 7.4.0 where the management toolbar search is reachable by users or attackers. The bundle does not establish broader Liferay versions or products as affected.
Exploitation context
The source bundle does not show CISA KEV listing, active exploitation, public exploit use, or exploitation prevalence. Treat this as a confirmed vendor-referenced XSS issue with incomplete public risk detail.
Researcher notes
The evidence is narrow: Liferay Portal 7.4.0, Frontend Taglib, management toolbar search, keywords parameter, XSS. The bundle lacks scoring, authentication context, payload behavior, fixed build details, and exploit evidence, so validation should stay close to vendor advisory data.
Mitigation direction
- Identify any Liferay Portal 7.4.0 deployments in production or externally reachable environments.
- Review the Liferay advisory for fixed versions or vendor-supported workaround details.
- Prioritize vendor-guided upgrade or remediation for exposed management toolbar deployments.
- Limit access to management interfaces while remediation is pending, where operationally feasible.
Validation and detection
- Confirm installed Liferay Portal versions against asset inventory and deployment records.
- Check whether management toolbar search is reachable in affected deployments.
- Review vendor advisory details before testing or closing the finding.
- Verify remediation by confirming the deployed version matches vendor guidance.
