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

Noroxi assessment

Priority: Monitor (action score 20/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.20% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No special conditions are required; it is repeatable.
  • Fixed version: Nozomi Networks CMC 26.1.0; Nozomi Networks Guardian 26.1.0.

Low priority for now. Upgrade to Nozomi Networks CMC 26.1.0; Nozomi Networks Guardian 26.1.0 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

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.
