Security readout for executives and security teams
Plain-English summary
CVE-2022-28978 is a stored XSS issue in Liferay. A user-controlled name can be saved and later rendered unsafely in the Site membership administration page. If an administrator or other privileged user views that page, script or HTML may execute in their browser context.
Executive priority
Treat this as a moderate-priority patching and exposure-management item. It is not documented as actively exploited in the supplied sources, but it can affect administrator browser sessions where vulnerable Liferay versions remain in use.
Technical view
The vulnerability affects Liferay Portal 7.0.1 through 7.4.1 and specified Liferay DXP releases before named fix packs or service packs. It is CWE-79 stored XSS via a user's name, rated CVSS 5.4 with network access, low complexity, low privileges, required user interaction, changed scope, and low confidentiality/integrity impact.
Likely exposure
Exposure is most likely in organizations running the listed Liferay Portal or DXP versions, especially where lower-privileged or remote users can control profile names that administrators later review in Site membership administration.
Exploitation context
The provided sources do not show active exploitation, and the CVE is not marked KEV. Exploitation requires a user with some privileges to store a crafted name and another user to view the affected administration page.
Researcher notes
Focus validation on the Site module's user membership administration page and rendering of user-controlled names. Do not assume broader Liferay modules are affected from these sources alone. Evidence supports stored XSS only in the named component and affected version ranges.
Mitigation direction
- Upgrade Liferay Portal beyond 7.4.1 or to the vendor-fixed DXP release level.
- For DXP, apply the referenced fix pack or service pack for your major version.
- Review Liferay's advisory for exact supported remediation guidance.
- Restrict who can create or rename users until patched.
- Monitor user names for unexpected HTML or script-like content.
Validation and detection
- Inventory Liferay Portal and DXP versions across internet-facing and internal systems.
- Compare installed versions against the affected ranges in the CVE description.
- Confirm applicable Liferay fix packs or service packs are installed.
- Review whether untrusted users can modify their displayed names.
- Check Site membership administration pages in a safe test environment for proper output encoding.
