Attackers can harvest cleartext passwords via Panduit IntraVUE API vulnerabilities

馃毃 Cleartext passwords stored within the Pronetiqs Panduit IntraVUE API could allow an attacker to harvest credentials easily. If you are running version 3.2.1a14 or older, your first move should be checking your API access logs and planning an upgrade. This is a high-severity issue because it requires no special privileges to exploit.

Summary

A vulnerability in Pronetiqs Panduit IntraVUE allows for the exposure of cleartext credentials through its API. The flaw stems from how the system handles password storage, leaving sensitive information accessible in plaintext format.

The issue affects versions 3.2.1a14 and all prior releases. Because the vulnerability is tied to the API, any actor with network access to the service may be able to retrieve these credentials, potentially leading to unauthorized access or further lateral movement within an industrial control environment.

Technical Details

The core of the issue lies in a failure to properly protect sensitive authentication data during API interactions. Specifically, CVE-2026-40430 identifies that passwords are stored in a plaintext format rather than being hashed or encrypted.

When a user or an automated process interacts with the IntraVUE API, these unencrypted credentials can be retrieved. This lack of cryptographic protection means that any intercepted traffic or unauthorized API calls targeting specific endpoints could yield full password strings. The CVSS score of 7.5 reflects the high impact on confidentiality resulting from this exposure.

Affected products and fixed versions

The vulnerability is concentrated in the following product line:

Product Affected Versions Severity CVE
Panduit IntraVUE 3.2.1a14 and prior High (7.5) CVE-2026-40430

Why this matters for defenders

In industrial environments, credential theft often serves as the first step in more complex attack chains. If an attacker gains access to these plaintext passwords, they can impersonate legitimate users, modify configurations, or disrupt operational processes.

Since the vulnerability is accessible via the API, it presents a significant risk if the management interface is exposed to broader network segments. Defenders should assume that any account used within this system may have had its password compromised if the vulnerable version was active and reachable over the network.

Defender guidance

Immediate action is required to mitigate the risk of credential harvesting.

  1. Identify Versioning: Audit all Panduit IntraVue installations to confirm if they are running version 3.2.1a14 or an earlier release.
  2. Apply Updates: Prioritize upgrading to a newer, patched version provided by Pronetiqs that addresses the plaintext storage flaw.
  3. Credential Rotation: Once the system is patched, perform a mandatory password reset for all accounts used within the IntraVUE environment. Because the previous passwords were stored in plaintext, they must be considered compromised.
  4. Network Segmentation: Ensure that the API endpoints and management interfaces for these devices are not reachable from untrusted networks or the public internet. Limit access to specific, authorized administrative workstations only.
