Moderate
thinkst-marco published GHSA-qchx-hrfc-32wg Mar 30, 2021

Package

OpenCanary

Affected versions

< 0.6.1

Patched versions

0.6.1

Description

Impact

A remote attacker can distinguish between the fake MySQL service and a real one. This allows an attacker to determine if OpenCanary is running on a host (when the MySQL module is running).

Resolution

Upgrade to OpenCanary 0.6.1

Workarounds

Disable the MySQL module in OpenCanary's configuration file:

# opencanary.conf
...
  "mysql.enabled": false,
...

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.
