CVE-2022-44574: Ivanti Avalanche improper authentication allows unauthenticated property modification

Ivanti · Avalanche

Ivanti Avalanche 6.3.x and below contains an improper authentication flaw (CWE-287) that lets an unauthenticated attacker modify properties on a specific port. Because the change is made without credentials, it undermines trust in the affected service's configuration and can be a stepping stone to further abuse.

Description

An improper authentication vulnerability exists in Avalanche version 6.3.x and below allows unauthenticated attacker to modify properties on specific port.

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N

Automated analysis

Generated by VULONE's analysis model from the NVD record, CISA KEV and EPSS data on 19 September 2026. Confidence: medium.

high priorityUnauthenticated network-reachable integrity impact with a high EPSS score, though no confirmed in-the-wild exploitation is documented.

What it is

Ivanti Avalanche 6.3.x and below contains an improper authentication flaw (CWE-287) that lets an unauthenticated attacker modify properties on a specific port. Because the change is made without credentials, it undermines trust in the affected service's configuration and can be a stepping stone to further abuse.

Impact

An attacker gains the ability to alter properties on the affected port without authenticating, giving them a foothold to influence device or server behavior. The CVSS vector shows high integrity impact with no confidentiality or availability impact.

Attack surface

Reachable over the network on a specific port with no authentication and no user interaction required, per the CVSS vector AV:N/AC:L/PR:N/UI:N. The description does not name the port or the exact protocol involved.

Exploitation

Not listed in CISA KEV and no public exploit or ransomware use is documented in the record, but EPSS is high at roughly 0.65 (99th percentile), indicating elevated likelihood of attempted exploitation.

What to do

  • Upgrade Avalanche to a version above 6.3.x as directed by the Ivanti advisory.
  • Restrict network access to the affected port to trusted management hosts only.
  • Segment Avalanche management interfaces from untrusted networks and the internet.
  • Monitor the vendor advisory for updated fixed versions and apply them promptly.

Detection

  • Alert on unexpected configuration or property changes on Avalanche hosts and correlate with source IPs.
  • Monitor network traffic to the affected port for unauthenticated write or modification attempts.
  • Baseline normal property-change activity and flag changes outside maintenance windows.

This assessment is produced automatically and is not human-reviewed. Verify against the vendor advisory before acting on it.
