CVE-2025-0283: Ivanti Connect Secure vulnerability

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 local authenticated attacker to escalate their privileges.

CVSS 7.0 High EPSS 17.5% · p97 Check exposure

Should you act?

High exploit likelihood

EPSS ranks it in the top 5% of all CVEs for likely exploitation in the next 30 days. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.

  • No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
  • EPSS 17.5%, percentile 97: FIRST’s model estimates a 17.5% chance of exploitation activity in the next 30 days, higher than 97% of all scored CVEs (very high). EPSS is a probability, not a verdict.
  • Needs local access needed. Lower urgency for most teams unless an attacker could already run code on the machine.
  • Editorial verdict: Check exposure. Ivanti Connect Secure Zero-Day RCE (CVE-2025-0282) — A real zero-day used for espionage and patched in January 2025; if you ran Connect Secure below 22.7R2.5 last winter, a clean patch level today does not prove you were never backdoored.
