Overview

CVE-2024-1491 is a high-severity vulnerability. It was published on April 18, 2024 and has a CVSS 3.1 base score of 7.5 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

The devices allow access to an unprotected endpoint that allows MPFS

file system binary image upload without authentication. The MPFS2 file

system module provides a light-weight read-only file system that can be

stored in external EEPROM, external serial flash, or internal flash

program memory. This file system serves as the basis for the HTTP2 web

server module, but is also used by the SNMP module and is available to

other applications that require basic read-only storage capabilities.

This can be exploited to overwrite the flash program memory that holds

the web server's main interfaces and execute arbitrary code.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
