Pgsync Contains Cleartext Transmission of Sensitive Information

High severity GitHub Reviewed Published Apr 27, 2021 to the GitHub Advisory Database • Updated Aug 25, 2023

Package

bundler pgsync (RubyGems)

Affected versions

< 0.6.7

Patched versions

0.6.7

Description

pgsync before 0.6.7 is affected by Information Disclosure of sensitive information. Syncing the schema with the --schema-first and --schema-only options is mishandled. For example, the sslmode connection parameter may be lost, which means that SSL would not be used.

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.
