CVE-2025-0282
A stack-based buffer overflow in Ivanti Connect Secure before version 22.7R2.5, Ivanti Policy Secure before version 22.7R1.2, and Ivanti Neurons for ZTA gateways before version 22.7R2.3 allows a remote unauthenticated attacker to achieve remote code execution.

Can a WAF block it? Partly. Cloudflare publishes WAF a rule written for this CVE. Such rules block the known exploit requests and buy time, but attackers can change the request to get past them, so they do not replace the patch.

Is CVE-2025-0282 being exploited?
Yes. CVE-2025-0282 appears in CISA's Known Exploited Vulnerabilities catalog, which means exploitation in the wild has been confirmed and reported. Treat it as active rather than theoretical, and patch it ahead of higher-scoring vulnerabilities that carry no exploitation evidence.
How severe is CVE-2025-0282?
CVE-2025-0282 is rated Critical with a CVSS score of 9.0. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.
Is there a patch for CVE-2025-0282?
Yes. A fix has been recorded for CVE-2025-0282. The vendor advisory is the authority on the exact fixed version — apply it from there rather than from a summary.
What does CVE-2025-0282 affect?
CVE-2025-0282 affects ivanti:connect_secure, ivanti:neurons_for_zero-trust_access, ivanti:policy_secure. Confirm the exact affected versions against the vendor advisory before deciding you are exposed.
Exploitation status reflects CISA's KEV catalog as we last synced it. Check the catalog directly.
- affected>= 22.7R2 and <= 22.7R2.4
- affected>= 22.7R2 and <= 22.7R2.3
- affected>= 22.7R1 and <= 22.7R1.2
As published in the CVE Program record. A version outside these ranges is not a statement that it is unaffected — vendors sometimes understate a range, and distribution-backported builds carry upstream numbers that do not reflect what was patched into them.
