Description

The misconfiguration in the sudoers configuration of the operating system in
Infinera G42 version R6.1.3 allows low privileged OS users to
read/write physical memory via devmem command line tool.
This could
allow sensitive information disclosure, denial of service, and privilege
escalation by tampering with kernel memory.

Details: The output of "sudo -l" reports the presence of "devmem" command
executable as super user without using a password. This command allows
to read and write an arbitrary memory area of the target device,
specifying an absolute address.

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.

Weaknesses

Incorrect Privilege Assignment

A product incorrectly assigns a privilege to a particular actor, creating an unintended sphere of control for that actor. Learn more on MITRE.
