CVE-2026-3660
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 · uneditedIBM Engineering Lifecycle Management 7.0.3, 7.1.0, and 7.2.0 could allow an unauthenticated remote attacker to update server property files that would allow them to gain unauthorized access to the application.
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 confidenceIBM Engineering Lifecycle Management versions 7.0.3, 7.1.0, and 7.2.0 contain an insecure direct object reference vulnerability that allows an unauthenticated remote attacker to update server property files. By modifying these configuration files, an attacker can gain unauthorized access to the application and potentially escalate privileges.

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 installed version of IBM Engineering Lifecycle ManagementCheck the product version through the admin console, installation directory, or by querying the application server (typically found in /opt/IBM/ELM or the installation root directory). Look for a version file or check the About dialog in the web interface.Affected if The installed version matches 7.0.3, 7.1.0, or 7.2.0 exactly
-
Locate server property and configuration filesIdentify configuration files in the application server directory, typically including property files such as web.xml, server.xml, or custom property files under the conf or config directories in the IBM ELM installation path.Affected if Server property files exist and are accessible to the web application without authentication
-
Inspect server property files for unauthorized modificationsReview all server property and configuration files for unexpected entries, especially modifications to authentication settings, user credentials, or security-related properties. Compare current files against known-good backups or baseline configurations.Affected if Property files contain unauthorized changes, new user entries, or modified authentication configurations
-
Check for external network access to configuration endpointsReview web server or application server access logs for unauthenticated requests to configuration or property file update endpoints (such as paths ending in /admin, /config, or property modification URLs).Affected if Unauthenticated requests to configuration update endpoints are present in logs
You are affected if the installed IBM Engineering Lifecycle Management version is exactly 7.0.3, 7.1.0, or 7.2.0 and server property files can be modified without authentication or show signs of unauthorized changes.

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.
From vendor dataApply IBM's security patch or upgrade to a supported version. If immediate patching is not possible, restrict network access to administrative interfaces and monitor for unauthorized configuration changes.
