CVE-2021-20535
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 Jazz Reporting Service 6.0.6.1, 7.0, 7.0.1, and 7.0.2 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. IBM X-Force ID: 198834.
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 Jazz Reporting Service contains a server-side request forgery (SSRF) vulnerability in versions 6.0.6.1 through 7.0.2. An authenticated attacker can manipulate the application to make unauthorized requests from the server to internal or external resources, potentially enabling network enumeration, access to internal services behind firewalls, or serving as a pivot point 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 Jazz Reporting Service installationLocate and determine the installed version of IBM Jazz Reporting Service in your environment. This is typically found in the product's About section, installation directory, or administration console under the Jazz Reporting Service component.Affected if The installed version is 6.0.6.1, 7.0, 7.0.1, or 7.0.2.
-
Verify the exact version numberAccess the Jazz Reporting Service administration interface or check the installation manifest/configuration files to confirm the precise version string installed.Affected if The version matches exactly 6.0.6.1, 7.0, 7.0.1, or 7.0.2.
-
Confirm the reporting service web interface is exposedCheck if the Jazz Reporting Service web interface is accessible over the network. This is typically accessible on the application server port under the /reports or similar endpoint.Affected if The reporting service HTTP interface is accessible from the network.
-
Determine if authenticated access is possibleVerify whether user accounts exist that can authenticate to the Jazz Reporting Service, as this SSRF vulnerability requires an authenticated attacker.Affected if Valid user credentials can be used to access the reporting service.
Your environment is affected if IBM Jazz Reporting Service version 6.0.6.1, 7.0, 7.0.1, or 7.0.2 is installed and the reporting service interface is network-accessible with valid authentication available.

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 the vendor patch when available. In the interim, implement strict network segmentation, restrict outbound access from the application server, and monitor for unusual request patterns to internal IP ranges or non-standard ports.
