CVE Record

CVE-2021-20347: IBM Jazz Foundation and IBM Engineering products are vulnerable to server-side request forgery (SSRF).

IBM Jazz Foundation and IBM Engineering products are 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: 194596.

Security readout for executives and security teams

Plain-English summary

CVE-2021-20347 is an authenticated SSRF issue in IBM Jazz Foundation and related IBM Engineering products. A logged-in attacker could make the affected server send requests on their behalf, which may expose internal network information or support follow-on attacks.

Executive priority

Prioritize remediation for exposed or widely used engineering lifecycle systems, especially where they can reach sensitive internal services. The issue is moderate, but SSRF can become more serious in segmented networks with weak egress controls.

Technical view

The issue is network-reachable, low-complexity, requires low privileges, and needs no user interaction. IBM rates it CVSS 3.0 score 5.4 with low confidentiality and integrity impact and no availability impact. The supplied record lists SSRF and IBM X-Force ID 194596.

Likely exposure

Exposure is most likely in organizations running the listed IBM Rational and Engineering Lifecycle products at versions 6.0.6, 6.0.6.1, 7.0, 7.0.1, 7.0.2, or listed 7.0.0 variants. Internet-facing or broadly accessible deployments raise urgency.

Exploitation context

The supplied sources do not show CISA KEV listing or active exploitation. The CVSS vector marks exploit code maturity as unproven. Treat this as a credible authenticated attack path, not as a confirmed in-the-wild campaign.

Researcher notes

Key constraints are authenticated access, low complexity, no UI requirement, and unchanged scope. The supplied data does not include a specific vulnerable endpoint, proof of exploitation, or detailed fix instructions, so validation should remain defensive and advisory-driven.

Mitigation direction

  • Identify affected IBM Jazz Foundation and Engineering Lifecycle deployments.
  • Review IBM advisory guidance for product-specific remediation or supported updates.
  • Restrict access to affected applications to trusted users and networks.
  • Limit server egress to internal metadata, administrative, and sensitive network services.
  • Review logs for unusual server-initiated requests after suspicious authenticated activity.

Validation and detection

  • Inventory product names and versions against the affected list.
  • Confirm whether affected instances are internet-facing or internally reachable by many users.
  • Check authentication and authorization boundaries for low-privilege accounts.
  • Review outbound network controls from application servers.
  • Verify remediation status using IBM support guidance.
