CVE-2025-40900: Angular template injection in Reports in Guardian/CMC before 26.1.0

An Angular template injection vulnerability was discovered in the Reports functionality due to improper validation of an input parameter. An authenticated user with report privileges can define a malicious report containing an Angular template payload, or a victim can be socially engineered to import a malicious report template. When the victim views or imports the report, the Angular template executes in their browser context, allowing the attacker to modify application data, or disrupt application availability. Full XSS exploitation and direct information disclosure are prevented by the existing input validation and Content Security Policy configuration.

Security readout for executives and security teams

Plain-English summary

An authenticated report user can create a harmful report, or persuade another user to import one. Opening or importing it can run Angular template content in the victim’s browser, potentially changing application data or disrupting service. Existing validation and Content Security Policy reportedly prevent full cross-site scripting and direct information disclosure.

Executive priority

Schedule remediation through normal vulnerability-management timelines, prioritizing systems with many report users or weak privilege controls. Escalate if suspicious report imports, unauthorized data changes, or availability disruptions are found. Current evidence supports moderate urgency rather than an emergency response.

Technical view

CVE-2025-40900 is a CWE-1336 Angular template injection in Nozomi Networks Guardian and CMC Reports. Improper parameter validation permits browser-context template execution after a privileged user creates a report or a victim imports one. It has CVSS 4.0 score 5.1; confidentiality impact is rated none, while integrity and availability impacts are low.

Likely exposure

Exposure is limited to Guardian or CMC deployments before 26.1.0 where users can define reports or import untrusted report templates. Authentication, report privileges, or victim interaction are required. The bundle’s structured affected-version entries are inconclusive, so confirm exact applicability against the vendor advisories.

Exploitation context

The supplied evidence does not establish active exploitation, and the CVE is not identified as KEV. Exploitation requires a report-privileged account or social engineering that convinces a victim to import a malicious template. Existing validation and CSP constrain the reported impact.

Researcher notes

The reported vector is CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N. Full XSS and direct disclosure are reportedly blocked. The title defines affected releases as before 26.1.0, but the structured affected entries list version “0” with default unaffected; consult vendor advisories for authoritative version mapping.

Mitigation direction

  • Upgrade Guardian and CMC installations before 26.1.0 to version 26.1.0 or later, subject to vendor guidance.
  • Restrict report creation and import privileges to trusted, necessary accounts.
  • Do not import report templates from untrusted or unverified sources.
  • Review the Nozomi and Siemens advisories for product-specific remediation requirements.

Validation and detection

  • Inventory Guardian and CMC versions and identify installations earlier than 26.1.0.
  • Review which accounts possess report creation or import privileges.
  • Audit recent report creation, import, and viewing activity for unexpected templates or changes.
  • Confirm Content Security Policy remains enabled and matches vendor-supported configuration.
  • Verify the installed version and remediation status against the applicable vendor advisory.
