CVE-2022-28977

Liferay Portal and Liferay DXP HtmlUtil.escapeRedirect Can Be Circumvented

HtmlUtil.escapeRedirect in Liferay Portal 7.3.1 through 7.4.2, and Liferay DXP 7.0 fix pack 91 through 101, 7.1 fix pack 17 through 25, 7.2 fix pack 5 through 14, and 7.3 before service pack 3 can be circumvented by using multiple forward slashes, which allows remote attackers to redirect users to arbitrary external URLs via the (1) 'redirectparameter (2)FORWARD_URL` parameter, and (3) others parameters that rely on HtmlUtil.escapeRedirect.

Untrusted input controls a URL used for redirection, which can forward users to attacker-controlled sites. Typical impact: phishing and credential harvesting via a trusted domain.

CVE-2022-28977 has a CVSS score of 6.1 (Medium). The vector is network-reachable, no privileges required, and user interaction required. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (7.4.3.4-ga4, 7.0.10.fp101, 7.1.10.fp25, 7.2.10.fp14, 7.9.0); upgrading removes the vulnerable code path.

It is fixed in 7.4.3.4-ga4, 7.0.10.fp101, 7.1.10.fp25, 7.2.10.fp14, 7.9.0. Untrusted input controls a URL used for redirection, which can forward users to attacker-controlled sites.
2. How severe is CVE-2022-28977? CVE-2022-28977 has a CVSS score of 6.1 (Medium). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which packages are affected by CVE-2022-28977?
   • com.liferay.portal:release.portal.bom (maven) (versions >= 7.3.1-ga2, < 7.4.3.4-ga4)
   • com.liferay.portal:release.dxp.bom (maven) (versions >= 7.0.10.fp91, < 7.0.10.fp101)
   • com.liferay.portal:com.liferay.util.java (maven) (versions < 7.9.0)
4. Is there a fix for CVE-2022-28977? Yes. CVE-2022-28977 is fixed in 7.4.3.4-ga4, 7.0.10.fp101, 7.1.10.fp25, 7.2.10.fp14, 7.9.0. Upgrade to this version or later.
5. Is CVE-2022-28977 exploitable, and should I be worried? Whether CVE-2022-28977 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2022-28977 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
