CVE-2025-43752
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 · uneditedLiferay Portal 7.4.0 through 7.4.3.132, and Liferay DXP 2025.Q1.0 through 2025.Q1.4, 2024.Q4.0 through 2024.Q4.7, 2024.Q3.1 through 2024.Q3.13, 2024.Q2.0 through 2024.Q2.13, 2024.Q1.1 through 2024.Q1.15 and 7.4 GA through update 92 allow users to upload an unlimited amount of files through the object entries attachment fields, the files are stored in the document_library allowing an attacker to cause a potential DDoS.
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 · high confidenceLifteray Portal and DXP allow users to upload unlimited files through object entry attachment fields, with files stored in document_library. This resource exhaustion vulnerability can be exploited to cause denial of service by filling storage or overwhelming the system.

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 Liferaya product and versionAccess the Liferaya Control Panel or check the product bundle for the exact version number (typically found in portal-impl/build.properties or via the Gogo shell command 'ver' or through the Control Panel > Configuration > Server Information)Affected if The installed version falls within any of these ranges: 2024.Q1.1 to 2024.Q1.15, 2024.q2.0 to 2024.q2.13, 2024.q3.1 to 2024.q3.13, 2024.Q4.0 to 2024.Q4.10, 2025.Q1.0 to 2025.Q1.4, 7.4.0 to 7.4.3.132, or equals 7.4 (for DXP)
-
Verify if object entry attachment fields are in useNavigate to Control Panel > Object > Objects and review any object definitions that contain attachment fields, or query the ObjectDefinition table in the database for fields where 'type' = 'Attachment'Affected if Any custom or out-of-the-box object definitions include attachment-type fields that are active in the system
-
Check file upload limits on attachment fieldsInspect each object entry definition with attachment fields, look for 'maximum size' and 'maximum number of files' settings in the field configuration panel under Control Panel > Object > Objects > [Object Name] > Fields > [Attachment Field]Affected if The attachment field configuration shows no maximum size limit or allows unlimited files (maximum count not set or set to unlimited)
-
Inspect document_library storage limitsCheck the document_library configuration in portal-ext.properties or via Control Panel > Content > Document Library > Configuration, looking for dl.file.max.size, dl.file.max.count, or storage quota settingsAffected if No global file size limits, file count limits, or storage quotas are configured for the document library
-
Check for rate limiting on upload endpointsReview any custom or third-party firewall/WAF configurations in front of Liferaya, or check portal.properties for custom upload rate limiting settingsAffected if No rate limiting is enforced on upload requests (POST to /o/c/object_entries or related attachment upload endpoints)
A system is affected if it runs any of the listed Liferaya versions AND has object entry attachment fields configured without upload limits or rate limiting, allowing unlimited file uploads to document_library storage.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped2024.Q1.162025.Q1.5
Implement file upload limits (size and count) on object entry attachment fields, add rate limiting for upload requests, and enforce proper access controls on document_library storage.
L Portal 7.4.3.133+ or DXP 2024.Q1.16+ (and subsequent quarterly patches for other affected releases)
- 1. Identify the current Liferay installation version (Portal or DXP)
- 2. For Liferay Portal 7.4.x: upgrade to version 7.4.3.133 or later
- 3. For Lifer Digital Experience Platform 2024.Q1.x: upgrade to 2024.Q1.16 or later
- 4. For DXP 2024.Q2.x: upgrade to 2024.Q2.14 or later if available, or the next available quarterly patch
- 5. For DXP 2024.Q3.x: upgrade to 2024.Q3.14 or later if available, or the next available quarterly patch
- 6. For DXP 2024.Q4.x: upgrade to 2024.Q4.11 or later if available, or the next available quarterly patch
- 7. Verify the upgrade by checking the Liferays release notes for CVE-2025-43752
- 8. Test the object entry attachment functionality to confirm the fix is applied
