CVE-2020-15841

Liferay Portal and Liferay DXP Potentially Reveal LDAP Server Password via Unsafe Connection

Liferay Portal before 7.3.0, and Liferay DXP 7.0 before fix pack 89, 7.1 before fix pack 17, and 7.2 before fix pack 4, does not safely test a connection to a LDAP server, which allows remote attackers to obtain the LDAP server's password via the Test LDAP Connection feature.

CVE-2020-15841 has a CVSS score of 8.3 (High). 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 (7.3.0, 7.0.10.fp89, 7.1.10.fp17, 7.2.10.fp4); upgrading removes the vulnerable code path.

2. How severe is CVE-2020-15841? CVE-2020-15841 has a CVSS score of 8.3 (High). 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-2020-15841?
   • com.liferay.portal:release.portal.bom (maven) (versions < 7.3.0)
   • com.liferay.portal:release.dxp.bom (maven) (versions >= 7.0.0, < 7.0.10.fp89)
4. Is there a fix for CVE-2020-15841? Yes. CVE-2020-15841 is fixed in 7.3.0, 7.0.10.fp89, 7.1.10.fp17, 7.2.10.fp4. Upgrade to this version or later.
5. Is CVE-2020-15841 exploitable, and should I be worried? Whether CVE-2020-15841 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-2020-15841 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.
7. How do I fix CVE-2020-15841?
   • Upgrade com.liferay.portal:release.portal.bom to 7.3.0 or later
   • Upgrade com.liferay.portal:release.dxp.bom to 7.0.10.fp89 or later
   • Upgrade com.liferay.portal:release.dxp.bom to 7.1.10.fp17 or later
   • Upgrade com.liferay.portal:release.dxp.bom to 7.2.10.fp4 or later
