Out-of-bounds Write in KUNBUS piControl

Nozomi Networks Labs identified a CWE-787: Out-of-bounds Write vulnerability in the process-image management functionality of KUNBUS piControl in version 2.6.2 that allows a local authenticated attacker with device configuration access to write attacker-controlled data outside the bounds of the process-image buffer and corrupt adjacent kernel memory, resulting in kernel memory corruption and denial of service, by supplying crafted device configuration data and crafted input through the piControl character device.

Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') in KUNBUS piControl

Nozomi Networks Labs identified a CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') vulnerability in the configuration and process-image management functionality of KUNBUS piControl in version 2.6.2 that allows a local authenticated attacker to trigger use-after-free and invalid pointer dereferences on kernel configuration objects, resulting in kernel memory corruption and denial of service, by issuing concurrent crafted requests through the piControl character device.

Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') in KUNBUS piControl

Nozomi Networks Labs identified a CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') vulnerability in the event notification functionality of KUNBUS piControl in version 2.6.2 that allows a local authenticated attacker to corrupt kernel heap and event-list state and disclose a small amount of adjacent kernel memory, resulting in kernel memory corruption and denial of service, by issuing concurrent crafted requests from multiple threads through the piControl character device.

Cross-Site Request Forgery (CSRF) in KUNBUS PiCtory

Nozomi Networks Labs identified a CWE-352: Cross-Site Request Forgery (CSRF) vulnerability in the web-based configuration backend of KUNBUS PiCtory in version 2.16.0 that allows a remote unauthenticated attacker to perform state-changing operations in the context of an authenticated operator, including deletion of project and configuration files and reset of the control runtime, by inducing the victim's browser to submit crafted requests.

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in KUNBUS RevPiPyLoad

Nozomi Networks Labs identified a CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the file management functionality of the XML-RPC management interface of KUNBUS RevPiPyLoad in version 0.11.0 that allows a local unauthenticated attacker to read arbitrary files with the privileges of the RevPiPyLoad daemon, including sensitive configuration and credential material, by sending crafted requests to the local management service.

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in KUNBUS RevPiPyLoad

Nozomi Networks Labs identified a CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the file management functionality of the XML-RPC management interface of KUNBUS RevPiPyLoad in version 0.11.0 that allows a local unauthenticated attacker to delete arbitrary files with the privileges of the RevPiPyLoad daemon, resulting in loss of configuration integrity and denial of service, by sending crafted requests to the local management service.

KUNBUS Revolution Pi Authentication Bypass by Primary Weakness

KUNBUS Revolution Pi OS Bookworm 01/2025 is vulnerable because authentication is not configured by default for the Node-RED server. This can give an unauthenticated remote attacker full access to the Node-RED server where they can run arbitrary commands on the underlying operating system.

RevPi Webstatus application is vulnerable to an authentication bypass

An unauthorized remote attacker can bypass the authentication of the affected software package by misusing an incorrect type conversion. This leads to full compromise of the device

An attacker could retrieve plain-text credentials stored in a XML file on PR100088 Modbus gateway versions prior to Release R02 (or Software Version 1.1.13166) through FTP.

Registers used to store Modbus values can be read and written from the web interface without authentication in the PR100088 Modbus gateway versions prior to Release R02 (or Software Version 1.1.13166).

An attacker could retrieve passwords from a HTTP GET request from the Kunbus PR100088 Modbus gateway versions prior to Release R02 (or Software Version 1.1.13166) if the attacker is in an MITM position.

An attacker could specially craft an FTP request that could crash the PR100088 Modbus gateway versions prior to release R02 (or Software Version 1.1.13166).

PR100088 Modbus gateway versions prior to Release R02 (or Software Version 1.1.13166) may allow an attacker to be able to change the password for an admin user who is currently or previously logged in, provided the device has not been restarted.
