Race condition exploitation in KUNBUS piControl 2.6.2 allows a local authenticated attacker to corrupt kernel memory by issuing concurrent crafted requests through the piControl character device, triggering use-after-free and invalid pointer dereferences in kernel configuration objects. The flaw resides in the configuration and process-image management subsystem of this industrial Revolution Pi (RevPi) controller platform component, with potential impact spanning confidentiality, integrity, and availability per the CVSS 4.0 vector, though denial of service is the explicitly confirmed outcome. No public exploit code and no active exploitation have been identified at time of analysis; this was responsibly disclosed by Nozomi Networks Labs.
Kernel memory corruption in KUNBUS piControl version 2.6.2 allows a local authenticated attacker with device configuration access to write beyond process-image buffer boundaries, corrupting adjacent kernel memory and causing denial of service. The vulnerability resides in process-image management functionality and is triggered by supplying crafted device configuration data and crafted input through the piControl character device. No public exploit code or active exploitation has been confirmed at time of analysis, though the industrial OT context and kernel-level impact elevate operational priority for RevPi deployments.
Path traversal in KUNBUS RevPiPyLoad 0.11.0 enables local users to delete arbitrary files through the XML-RPC management interface without authenticating to the service, exploiting the daemon's own filesystem privileges via crafted requests. Discovered and reported by Nozomi Networks Labs, the flaw allows an attacker to corrupt configuration files or trigger denial of service on Revolution Pi industrial controllers, with integrity and availability impact classified as high. No public exploit code has been identified at time of analysis, and the product is not listed in the CISA KEV catalog.
Path traversal in KUNBUS RevPiPyLoad 0.11.0 exposes arbitrary file read via the XML-RPC management interface, allowing a local attacker to access sensitive files at daemon-level privileges. Nozomi Networks Labs discovered that the file management functionality of the local management service fails to sanitize directory path input before serving files, enabling escape from the intended file access scope. No public exploit code or CISA KEV listing exists at time of analysis; however, successful exploitation yields high confidentiality impact including potential exposure of credential material and configuration files critical to ICS environments.
Cross-site request forgery in KUNBUS PiCtory 2.16.0's web-based configuration backend allows remote unauthenticated attackers to perform destructive state-changing operations - including deletion of project and configuration files and resetting the control runtime - by inducing an authenticated operator's browser to submit crafted requests. This affects industrial OT environments where PiCtory manages Revolution Pi controller configurations. No public exploit has been identified at time of analysis, but the impact in ICS/OT contexts extends to potential disruption of control operations even at a 'low' CVSS integrity/availability rating.
Race condition in KUNBUS piControl 2.6.2 enables a local authenticated attacker to corrupt kernel heap memory and disclose adjacent kernel memory contents by issuing concurrent crafted requests through the piControl character device. The flaw resides in the event notification subsystem, where improper synchronization between threads allows an attacker to win a timing window and manipulate shared kernel state. No public exploit or active exploitation (CISA KEV) has been identified at time of analysis; the CVSS 4.0 score of 5.9 reflects the high-complexity, local-access nature of the attack.
Critical remote authentication bypass vulnerability affecting an unspecified software package, exploitable through improper type conversion handling (CWE-704). An unauthenticated network attacker can bypass authentication controls without user interaction to achieve complete device compromise including confidentiality, integrity, and availability violations. The vulnerability carries a maximum CVSS 3.1 score of 9.8 with network accessibility and low attack complexity, indicating high real-world exploitability risk; without access to KEV/EPSS data or POC confirmation, exploitation likelihood cannot be definitively assessed but the attack vector and complexity profile suggests active exploitation potential.
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. Rated high severity (CVSS 8.1), this vulnerability is remotely exploitable, no authentication required. No vendor patch available.
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. Rated high severity (CVSS 7.2), this vulnerability is remotely exploitable, low attack complexity. No vendor patch available.
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. Rated critical severity (CVSS 9.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
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. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
