CVE-2022-28982: A cross-site scripting (XSS) vulnerability in Liferay Portal v7.3.3 through v7.4.2 and Liferay DXP v7.3 bef...
A cross-site scripting (XSS) vulnerability in Liferay Portal v7.3.3 through v7.4.2 and Liferay DXP v7.3 before service pack 3 allows attackers to execute arbitrary web scripts or HTML via a crafted payload injected into the name of a tag.
Security readout for executives and security teams
Plain-English summary
CVE-2022-28982 is an XSS issue in certain Liferay Portal and DXP versions. An attacker could get script or HTML to run in a user’s browser through a crafted tag name. Business risk is mainly account/session exposure, content tampering, and user trust impact, not direct server takeover.
Executive priority
Treat as a scheduled but real remediation item. It is not presented as actively exploited, but exposed portals can turn browser-side compromise into credential, session, or reputational risk.
Technical view
The issue is CWE-79 XSS in Liferay Portal 7.3.3 through 7.4.2 and Liferay DXP 7.3 before service pack 3. The CVSS 3.1 score is 6.1: network exploitable, low complexity, no privileges required, user interaction required, changed scope, low confidentiality and integrity impact, no availability impact.
Likely exposure
Organizations running affected Liferay Portal or Liferay DXP versions with tag selection functionality reachable by users may be exposed. Public-facing portals increase risk, especially where users follow links or interact with attacker-controlled content.
Exploitation context
The source bundle does not show known active exploitation, and KEV status is false. Exploitation requires user interaction and relies on crafted tag-name content causing script or HTML execution in a victim browser context.
Researcher notes
Evidence supports XSS via crafted tag names, with CVSS indicating no required privileges but required user interaction. The bundle does not provide exploit proof, observed exploitation, or complete fixed-version mapping for every affected product line.
Mitigation direction
Check Liferay’s advisory for fixed versions and upgrade guidance.
Prioritize upgrades for public-facing or externally used Liferay portals.
Move Liferay DXP 7.3 deployments to service pack 3 or later if applicable.
Restrict access to affected portal functions until remediation is complete.
Review WAF or content filtering only as temporary compensating control.
Validation and detection
Inventory Liferay Portal and DXP versions across environments.
Confirm whether Portal 7.3.3 through 7.4.2 is present.
Confirm whether DXP 7.3 is below service pack 3.
Review portal logs for suspicious tag-name activity or abnormal script injection attempts.
Verify remediation against the vendor advisory, not only package names.

Client-side and session-facing weaknesses should be reviewed alongside initial-access and user-execution behaviors. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
