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.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
