# CVE-2025-0282: Ivanti Connect Secure, Policy Secure, and ZTA Gateways Stack-Based Buffer Overflow Vulnerability

**Signal:** Exploited: patch now if you run it. CISA has confirmed exploitation in the wild. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Yes, if you run Ivanti Connect Secure, Policy Secure, and ZTA Gateways. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2025-01-08, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2025-01-15 ; treat that as the outer limit, not the target. CISA also lists it as known to be used in ransomware campaigns .
- EPSS 100.0% , percentile 100.0: FIRST’s model estimates a 100.0% chance of exploitation activity in the next 30 days, higher than 100.0% of all scored CVEs (very high). EPSS is a probability, not a verdict.
- Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
- 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.

## What it is

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.

## Affected products (CVE record)

- Ivanti Connect Secure: 22.7R2 <= 22.7R2.4
- Ivanti Policy Secure: 22.7R1 <= 22.7R1.2
- Ivanti Neurons for ZTA gateways: 22.7R2 <= 22.7R2.3

## Severity

- ivanti CVSS 3.1: 9 `CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H`

## Exploitation

- CISA KEV: added 2025-01-08; federal due date 2025-01-15. Known ransomware use: Known.
- CISA required action: Apply mitigations as set forth in the CISA instructions linked below to include conducting hunt activities, taking remediation actions if applicable, and applying updates prior to returning a device to service.
- CISA SSVC assessment: exploitation active , automatable no , technical impact total .
- FIRST EPSS (model of 2026-10-21): 99.98% probability of exploitation activity in the next 30 days; percentile 100.0.
