google-sheets-datasource: Generation of Error Message Containing Sensitive Information

CVE-2023-4457 is a high-severity generation of error message containing sensitive information vulnerability in google-sheets-datasource from Grafana, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 1.2.2 as the first without the flaw, so updating google-sheets-datasource to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.46% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update google-sheets-datasource to 1.2.2 or a later version.
  2. Read the advisory on grafana.com for workarounds and exact fixed builds.
  3. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

Grafana is an open-source platform for monitoring and observability. The Google Sheets data source plugin for Grafana, versions 0.9.0 to 1.2.2 are vulnerable to an information disclosure vulnerability. The plugin did not properly sanitize error messages, making it potentially expose the Google Sheet API-key that is configured for the data source. This vulnerability was fixed in version 1.2.2.

The underlying weakness: Generation of Error Message Containing Sensitive Information

The product generates an error message that includes sensitive information about its environment, users, or associated data.

How developers prevent this class of flaw

  • Handle exceptions internally and do not display errors containing potentially sensitive information to a user.
  • Use naming conventions and strong types to make it easier to spot when sensitive data is being used. When creating structures, objects, or other complex entities, separate the sensitive and non-sensitive data as much as possible.
  • Debugging information should not make its way into a production release.
