Ivanti Connect Secure, Policy and ZTA Gateways vulnerability
Stack-based buffer overflow in Ivanti Connect Secure, Policy Secure, and ZTA Gateways allows unauthenticated remote code execution.
Verdict
Today item, not a backlog item.
A stack-based buffer overflow vulnerability in Ivanti gateway products enables remote attackers to execute arbitrary code without authentication. Active exploitation and ransomware deployment have been observed.

01
Is it exploitable?
— the evidence, ranked above the scoreExploit available
Fully weaponized — public exploit code is cataloged for this vulnerability.We link the existence of the exploit; we do not host or redistribute payloads.
Reported exploitation
25 independent public reports of in-the-wild exploitation are cataloged.Distinct reporting sources (vendor, incident response, government); open them for the underlying claims.
Exploited in the wild
Listed in the CISA Known Exploited Vulnerabilities catalog (added 2025-04-04), flagged for known ransomware use.
Probability (EPSS)
EPSS 0.99961 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
Affected: Ivanti, Connect Secure, Policy Secure, and ZTA Gateways. Confirm exact fixed builds in the vendor advisory.
Weakness (CWE)
Mapped to CWE-121 Stack-based Buffer Overflow — weakness family: Memory safety.CWE assignment from the public NVD record; the weakness class drives how the flaw is exploited.
02
Who’s exploiting it?
— attribution turns risk into urgencyAttribution not established
No confirmed (advisory-backed) threat-actor attribution is established for this record. Absence of a named actor is not absence of compromise — see Coverage & confidence.
03
Why it matters
— the attack path, told twice: adversary, then board1
Front door — unauthenticated access narrative 1
Attacker
I craft a malicious network request that overflows a stack buffer in the vulnerable gateway service.
Business
The organization's perimeter security is bypassed, exposing internal networks to direct compromise.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I achieve code execution on the gateway with the privileges of the vulnerable service process.
Business
Attackers gain a foothold to pivot toward critical infrastructure, databases, and sensitive systems.
3
Lateral reach — past segmentation narrative 3
Attacker
I establish persistence and deploy ransomware payloads across the compromised environment.
Business
Operations halt, data is encrypted, and the organization faces extortion demands and potential data breach disclosure.
04
What to do
— defensible action- Remediate per the vendor advisory — confirm the fixed build for your version and verify exposure.1
Say it to the boardA vulnerability with this evidence profile is a defensible budget line, not a backlog ticket — fund the change against the proof above.
