Package

gomod ArduinoCreateAgent (Go)

Affected versions

<1.3.2

Patched versions

Description

Impact

The vulnerability affects the endpoint /upload which handles request with the filename parameter.
A user who has the ability to perform HTTP requests to the localhost interface, or is able to bypass the CORS configuration, can escalate his privileges to those of the user running the Arduino Create Agent service via a crafted HTTP POST request.

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.

CVE ID

CVE-2023-43802

Weaknesses

Path Traversal: '.../...//'

The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize '.../...//' (doubled triple dot slash) sequences that can resolve to a location that is outside of that directory. Learn more on MITRE.
