CVE-2025-43801
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedUnchecked input for loop condition vulnerability in XML-RPC in Liferay Portal 7.4.0 through 7.4.3.111, and older unsupported versions, and Liferay DXP 2023.Q4.0, 2023.Q3.1 through 2023.Q3.4, 7.4 GA through update 92, 7.3 GA through update 35, and older unsupported versions allows remote attackers to perform a denial-of-service (DoS) attacks via a crafted XML-RPC request.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceThis is an unchecked input vulnerability in Lifer's XML-RPC component where the loop condition is not properly validated. Attackers can send crafted XML-RPC requests with malicious input that controls loop execution, causing excessive resource consumption and leading to denial of service.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Lifer product and versionLocate the Lifer installation and determine the exact product (Lifer Digital Experience Platform or Lifer Portal) and version number from the system properties, build info, or admin console.Affected if The installed version falls within < 7.3, >= 2023.Q3.0 but < 2023.Q3.5, = 7.3, = 7.4 for DXP, or < 7.4.3.112 for Portal.
-
Confirm XML-RPC component is presentCheck the Lifer installation for the XML-RPC module or component. This may appear in the module list, plugin inventory, or system information page.Affected if XML-RPC functionality is installed or available in the Lifer instance.
-
Determine if XML-RPC is enabledInspect Lifer's configuration files (such as portal.properties, system.properties, or OSGi config files) and look for XML-RPC related settings or enablement flags.Affected if XML-RPC is explicitly enabled or configured to run in the environment.
-
Check for exposed XML-RPC endpointsReview the web server or reverse proxy configuration, and search for XML-RPC endpoint URLs (commonly /xmlrpc or /xmlrpc/* paths) that may be accessible externally.Affected if XML-RPC endpoints are exposed and reachable over the network.
A Lifer instance is affected if it runs a vulnerable version (DXP < 7.3, 7.3, 7.4, or >= 2023.Q3.0 < 2023.Q3.5; Portal < 7.4.3.112) AND has XML-RPC enabled and exposed.
Generated from the published advisory. Verify against your own configuration.

Apply vendor-supplied patches or upgrade to a non-vulnerable Lifer version. If XML-RPC is not required, consider disabling the XML-RPC functionality until the patch can be applied.
Liferay Portal 7.4.3.112+ or latest stable 7.4.x; DXP 2023.Q3.5+, 2023.Q4.1+, 7.3 update 36+, 7.4 update 93+
- 1. Identify the exact current version of Liferay Portal or DXP running in your environment
- 2. For Liferay Portal 7.4.x: Upgrade to version 7.4.3.112 or later
- 3. For Liferay DXP 2023.Q3.x: Upgrade to version 2023.Q3.5 or later
- 4. For Liferay DXP 2023.Q4.x: Upgrade to version 2023.Q4.1 or later
- 5. For Liferay DXP 7.3.x: Upgrade to update 36 or later
- 6. For Liferay DXP 7.4.x: Upgrade to update 93 or later
- 7. After upgrade, verify the XML-RPC service is functioning correctly
- 8. Test that the DoS vulnerability is no longer exploitable
