arduino-create-agent: Insufficient Verification of Data Authenticity
CVE-2023-43800 is a high-severity insufficient verification of data authenticity vulnerability in arduino-create-agent from Arduino, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. Affected arduino-create-agent versions: < 1.3.3. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.22% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Create Agent to 1.3.3 or a later version.
- Read the advisory on github.com for workarounds and exact fixed builds.
Affected products and versions
| Vendor | Product | Affected versions | Fixed in |
|---|---|---|---|
| Arduino | arduino-create-agent | < 1.3.3 | Not stated |
| Arduino | Create Agent | before 1.3.3 | 1.3.3 |

Official description
Arduino Create Agent is a package to help manage Arduino development. The vulnerability affects the endpoint `/v2/pkgs/tools/installed`. 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. This issue has been addressed in version `1.3.3`. Users are advised to upgrade. There are no known workarounds for this issue.

The underlying weakness: Insufficient Verification of Data Authenticity
The product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data.
