Security readout for executives and security teams
Plain-English summary
CVE-2022-42127 is an information disclosure issue in Liferay’s Friendly URL module. An unauthenticated remote attacker could view the history of friendly URLs assigned to a page. This does not allow data modification or service disruption, but may expose internal page history or naming patterns useful for reconnaissance.
Executive priority
Treat as a moderate-priority remediation item. It is not known to be actively exploited and has limited confidentiality impact, but unauthenticated remote access increases business relevance for public Liferay portals.
Technical view
Affected versions are Liferay Portal 7.4.3.5 through 7.4.3.36 and Liferay DXP 7.4 update 1 through 36. The module does not properly check user permissions, allowing network-based, unauthenticated access to friendly URL history. CVSS 3.1 is 5.3: AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N. CWE-276 is listed.
Likely exposure
Exposure is most relevant for internet-facing or partner-facing Liferay 7.4 deployments in the affected version ranges. The impact is limited to confidentiality of URL history, but public portals may be easier to probe remotely.
Exploitation context
The source bundle does not show CISA KEV listing or cited evidence of active exploitation. Exploitation requires network access and no authentication, but the disclosed impact is limited to reading friendly URL history, not gaining control or changing content.
Researcher notes
Evidence is limited to the CVE description and Liferay references. No exploit details, patch version, or workaround are provided in the supplied source bundle. Validate scope directly against Liferay’s advisory and LPE-17607 before making remediation claims.
Mitigation direction
- Identify Liferay Portal and DXP 7.4 instances and their exact update levels.
- Prioritize internet-facing affected deployments for review.
- Check Liferay’s advisory and LPE-17607 for vendor-supported remediation guidance.
- Restrict unnecessary external access to affected portal functions where feasible.
- Monitor web access logs for unusual friendly URL history access patterns.
Validation and detection
- Confirm whether deployed versions fall within the affected Liferay ranges.
- Review application configuration and exposure of Liferay portal endpoints.
- Verify remediation status against Liferay’s security advisory or issue record.
- Check logs for unauthenticated requests to Friendly URL-related functionality.
- Document any affected public pages and potentially exposed URL history.
