Ivanti Connect Secure and Policy vulnerability
Authentication bypass in Ivanti Connect Secure and Policy Secure web components allows attackers to access restricted resources by circumventing control checks, enabling potential lateral movement when chained with command injection flaws.
Verdict
Today item, not a backlog item.
This authentication bypass vulnerability in Ivanti gateway products poses critical risk due to active exploitation in ransomware campaigns. The flaw enables unauthenticated access to restricted resources, and when combined with command injection vulnerabilities, creates a pathway to full system comp

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
966 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 2024-01-10), flagged for known ransomware use.
Probability (EPSS)
EPSS 0.99986 — modeled likelihood of exploitation activity.EPSS is a daily-changing model output — open the source for today's value.
Severity / affected
CVSS 8.2 (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N) · Affected: Ivanti, Connect Secure and Policy Secure. Confirm exact fixed builds in the vendor advisory.CVSS — CNA-assigned (CVE.org), version 3.0, set at disclosure.
Weakness (CWE)
Mapped to CWE-287 Improper Authentication — weakness family: Authentication.CWE assignment from the public NVD record (may be stale); the weakness class drives how the flaw is exploited.
CISA SSVC (triage disposition)
Exploitation: active · Automatable: no · Technical Impact: totalCISA's own stakeholder-specific triage inputs, published in the CVE record (CISA Coordinator role). NOTE: this is CISA's three decision points; the final Act/Attend/Track decision also requires a Mission & Well-being input not published here, so no overall decision is asserted.
Currency of the record
CISA added this to its KEV catalog the same day the CVE record was published.KEV lag = CISA-KEV dateAdded − CVE.org datePublished; a floor on how long the known-exploited flaw sat in the public record before the federal catalog listed it. Severity/weakness here is CNA- or CISA-assigned (current at disclosure), independent of NVD's analysis backlog.
Public exploit available
Public exploit tooling is catalogued for this CVE (a functional/weaponized public exploit). Catalog entries: Metasploit module, nuclei template. We link the catalog page(s) only — no payload or code is hosted or restated here.Link, never host — the catalog page is the source; basicsecurity.net does not redistribute payloads.

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 bypass authentication controls in the Ivanti gateway web interface to gain unauthorized access to restricted administrative resources.
Business
Attackers gain initial foothold into the network perimeter without valid credentials, establishing persistence within critical infrastructure.
2
Keys to the kingdom — privilege/identity takeover narrative 2
Attacker
I chain this authentication bypass with command injection vulnerabilities to execute arbitrary code on the compromised gateway.
Business
The gateway becomes fully compromised, allowing attackers to pivot deeper into the network and establish command and control infrastructure.
3
Lateral reach — past segmentation narrative 3
Attacker
I use the compromised gateway to deploy ransomware payloads across the victim organization's network.
Business
Critical systems are encrypted and business operations halt, resulting in ransom demands and potential data exfiltration losses.
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.
