CVSS: 10.0EPSS: 0%CPEs: 28EXPL: 0CVE-2022-31481 – Remote Code Execution via buffer overflow in firmware update process
https://notcve.org/view.php?id=CVE-2022-31481
An unauthenticated attacker can send a specially crafted update file to the device that can overflow a buffer. This vulnerability impacts products based on HID Mercury Intelligent Controllers LP1501, LP1502, LP2500, LP4502, and EP4502 which contain firmware versions prior to 1.302 for the LP series and 1.296 for the EP series. The overflowed data can allow the attacker to manipulate the “normal” code execution to that of their choosing. An attacker with this level of access on the device can monitor all communications sent to and from this device, modify onboard relays, change configuration files, or cause the device to become unstable. Un atacante no autenticado puede enviar un archivo de actualización especialmente diseñado al dispositivo que puede desbordar un búfer. • https://www.corporate.carrier.com/product-security/advisories-resources • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
CVSS: 7.5EPSS: 0%CPEs: 28EXPL: 0CVE-2022-31480 – Unauthenticated Firmware Upload and Arbitrary Reboot
https://notcve.org/view.php?id=CVE-2022-31480
An unauthenticated attacker could arbitrarily upload firmware files to the target device, ultimately causing a Denial-of-Service (DoS). This vulnerability impacts products based on HID Mercury Intelligent Controllers LP1501, LP1502, LP2500, LP4502, and EP4502 which contain firmware versions prior to 1.302 for the LP series and 1.296 for the EP series. The attacker needs to have a properly signed and encrypted binary, loading the firmware to the device ultimately triggers a reboot. Un atacante no autenticado podría cargar arbitrariamente archivos de firmware en el dispositivo objetivo, causando en última instancia una denegación de servicio (DoS). Esta vulnerabilidad afecta a los productos basados en los controladores inteligentes HID Mercury LP1501, LP1502, LP2500, LP4502 y EP4502 que contienen versiones de firmware anteriores a 1.302 para la serie LP y 1.296 para la serie EP. • https://www.corporate.carrier.com/product-security/advisories-resources • CWE-425: Direct Request ('Forced Browsing') •
CVSS: 10.0EPSS: 0%CPEs: 28EXPL: 0CVE-2022-31479 – Remote Code Execution via command injection of the hostname
https://notcve.org/view.php?id=CVE-2022-31479
An unauthenticated attacker can update the hostname with a specially crafted name that will allow for shell commands to be executed during the core collection process. This vulnerability impacts products based on HID Mercury Intelligent Controllers LP1501, LP1502, LP2500, LP4502, and EP4502 which contain firmware versions prior to 1.302 for the LP series and 1.296 for the EP series. An attacker with this level of access on the device can monitor all communications sent to and from this device, modify onboard relays, change configuration files, or cause the device to become unstable. The injected commands only get executed during start up or when unsafe calls regarding the hostname are used. This allows the attacker to gain remote access to the device and can make their persistence permanent by modifying the filesystem. • https://www.corporate.carrier.com/product-security/advisories-resources • CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') CWE-693: Protection Mechanism Failure •
