CVE-2025-36085
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 Concert 1.0.0 through 2.0.0 Software is vulnerable to server-side request forgery (SSRF). This may allow an authenticated attacker to send unauthorized requests from the system, potentially leading to network enumeration or facilitating other attacks.
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 confidenceIBM Concert versions 1.0.0 through 2.0.0 contains a server-side request forgery (SSRF) vulnerability that allows authenticated attackers to craft requests causing the server to make unauthorized connections to internal or external resources. This can enable network enumeration, access to internal services, cloud metadata endpoints, or serve as a pivot for further attacks.

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 IBM Concert installationSearch for IBM Concert software on the system. Check common installation directories, look for processes named 'concert' or 'ibm-concert', and review installed software packages using system package managers or application inventory tools.Affected if IBM Concert is installed on the system
-
Determine installed versionRun 'concert --version' or check the application metadata/version file in the installation directory. Compare the version number against the affected range.Affected if Installed version is >= 1.0.0 and < 2.1.0
-
Verify authentication is enabledReview IBM Concert configuration files (typically in config/ or etc/ directories) for authentication settings. Check if user authentication is enforced for API endpoints and web interfaces.Affected if Authentication is disabled or not properly configured, allowing unauthenticated access to the service
-
Inspect access logs for suspicious URL patternsReview IBM Concert access and audit logs for requests containing internal IP addresses (127.0.0.1, 10.x.x.x, 172.16.x.x, 192.168.x.x), localhost, cloud metadata endpoints (169.254.169.254), or unusual internal hostnames.Affected if Logs contain requests to internal infrastructure or known SSRF indicators that were not initiated by legitimate internal tools
-
Check network exposureDetermine if the IBM Concert service is exposed to the internet or untrusted networks. Review firewall rules, reverse proxy configurations, and network ACLs controlling access to the Concert service ports.Affected if Service is directly accessible from untrusted networks without proper network segmentation
A user is affected if IBM Concert versions 1.0.0 through 2.0.0 are installed and the service is accessible (with or without authentication), as authenticated attackers could exploit the SSRF vulnerability to reach internal resources.

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 · scoped2.1.0
Implement strict allowlist-based URL validation with deny-lists for internal IP ranges (127.0.0.0/8, 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16) and cloud metadata endpoints to prevent access to internal infrastructure.
2.1.0
- 1. Backup current IBM Concert installation and all associated data
- 2. Review IBM Concert 2.1.0 release notes for any migration requirements or prerequisites
- 3. Stop the IBM Concert service
- 4. Upgrade IBM Concert from version 1.0.0-2.0.0 to version 2.1.0 or later
- 5. Verify the upgrade was successful and the service starts properly
- 6. Confirm the SSRF vulnerability is remediated by testing that the application no longer allows unauthorized server-side requests
