Always incorrect control flow in github.com/mojocn/base64Captcha

Moderate severity GitHub Reviewed Published Dec 12, 2023 to the GitHub Advisory Database • Updated Dec 14, 2023

Package

gomod github.com/mojocn/base64Captcha (Go)

Affected versions

< 1.3.6

Patched versions

1.3.6

Description

When using the default implementation of Verify to check a Captcha, verification can be bypassed. For example, if the first parameter is a non-existent id, the second parameter is an empty string, and the third parameter is true, the function will always consider the Captcha to be correct.

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.
