Security readout for executives and security teams
Plain-English summary
This flaw lets an attacker trick a user into accepting a Liferay site’s terms of use by luring them to a malicious page. It affects older Liferay Portal and DXP releases. The source bundle does not show active exploitation, but the CVSS score is high and the issue is remotely triggerable with user interaction.
Executive priority
Treat this as a high-priority patching item for affected Liferay systems, especially public portals. There is no cited active exploitation, but the issue involves remote social engineering against users and has a high CVSS score.
Technical view
CVE-2021-29050 is a CSRF issue in the Liferay terms of use page. A remote unauthenticated attacker can use social engineering to cause a user’s browser to submit a terms-acceptance action. The affected versions named are Liferay Portal before 7.3.6, DXP 7.3 before SP1, and DXP 7.2 before FP11.
Likely exposure
Exposure is limited to organizations running the named older Liferay Portal or DXP versions with the terms of use workflow reachable to users. The bundle does not identify affected CPEs or deployment-specific conditions beyond those versions.
Exploitation context
The provided sources describe social engineering and a malicious page as the attack path. CISA KEV is false, and no provided source states active exploitation or public weaponization.
Researcher notes
The source bundle is narrow: it identifies the CSRF class, affected Liferay version ranges, and fixed release thresholds. It does not provide CPEs, detailed root cause, indicators of compromise, or exploit availability evidence.
Mitigation direction
- Upgrade Liferay Portal to 7.3.6 or later.
- Apply Liferay DXP 7.3 service pack 1 or later.
- Apply Liferay DXP 7.2 fix pack 11 or later.
- Check Liferay’s advisory for supported upgrade guidance.
- Prioritize internet-facing or externally accessible Liferay deployments.
Validation and detection
- Inventory all Liferay Portal and DXP versions in production and staging.
- Confirm installed service packs or fix packs meet the fixed versions.
- Verify the terms of use page is no longer on a vulnerable build.
- Review audit records for unexpected terms-of-use acceptance events.
- Check vendor guidance for any additional environment-specific validation.

Cross-Site Request Forgery (CSRF)
Cross-Site Request Forgery (CSRF) represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
