CVE-2024-42210
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 · uneditedA Stored cross-site scripting (XSS) vulnerability affects HCL Unica Marketing Operations v12.1.8 and lower. Stored cross-site scripting (also known as second-order or persistent XSS) arises when an application receives data from an untrusted source and includes that data within its later HTTP responses in an unsafe way.
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 confidenceStored XSS vulnerability in HCL Unica Marketing Operations v12.1.8 and lower allows malicious scripts to be persisted in the application and executed when other users view affected content, as the application fails to properly sanitize untrusted data before storing and later rendering it in HTTP responses.

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.
-
Check the installed version of HCL Unica Marketing OperationsAccess the application admin panel or check the product documentation for the version information. Typically found in Help > About or through the system administration console.Affected if The installed version is 12.1.8 or lower (anything below 12.1.9)
-
Identify user input fields in the applicationNavigate through Unica Marketing Operations and locate forms, text inputs, and data entry fields where users can submit content that gets stored and displayed to other users.Affected if The application stores and displays user-submitted content without visible sanitization controls
-
Test for input validation on stored data fieldsSubmit a benign test script (such as <script>alert('test')</script>) in a user input field and have another user session view the stored content to observe if the script executes.Affected if The submitted script tags are rendered as-is without encoding or sanitization when viewed by other users
-
Review application logs for XSS-related security eventsCheck the Unica Marketing Operations server logs and application audit logs for any XSS detection warnings or blocked payloads related to user input fields.Affected if No XSS sanitization is being applied and the application accepts potentially malicious input without rejection
-
Confirm the application lacks web application firewall or input validationReview the application configuration settings or security settings in the Unica administration console to verify if input validation, output encoding, or content security policies are enabled.Affected if No input validation, output encoding, or Content Security Policy headers are configured for user input fields
You are affected if HCL Unica Marketing Operations is installed at version 12.1.8 or lower and the application accepts and displays user-submitted content without proper sanitization.
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 · scoped12.1.9
Apply vendor patches from HCL for Unica Marketing Operations and implement proper input validation with context-aware output encoding to neutralize malicious script payloads before storage and display.
12.1.9
- 1. Download HCL Unica Marketing Operations version 12.1.9 from the official HCL support portal (support.hcl-software.com)
- 2. Create a complete backup of your current HCL Unica installation including the database
- 3. Stop all HCL Unica services before proceeding with the upgrade
- 4. Install or upgrade to version 12.1.9 following the official HCL Unica upgrade documentation
- 5. Restart all HCL Unica services after the upgrade completes
- 6. Verify the version installed is 12.1.9 and test that the stored XSS vulnerability is no longer present
