Remote for TLS session may be trusted despite constraints

Moderate
Sainan published GHSA-84hj-7j2v-w665 May 1, 2024

Package

Pluto

Affected versions

0.9.0-0.9.2

Patched versions

>= 0.9.3

Description

Impact

An attacker with the ability to actively intercept network traffic would be able to use a specifically-crafted certificate to fool Pluto into trusting it to be the intended remote for the TLS session.

This results in the HTTP library and socket.starttls providing less transport integrity than expected. The HTTP library in WASM builds is not affected.

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.
