User Impersonation in converse.js

Moderate severity GitHub Reviewed Published Sep 11, 2020 to the GitHub Advisory Database • Updated Jan 9, 2023

Package

npm converse.js (npm)

Affected versions

< 1.0.7
>= 2.0.0, < 2.0.5

Patched versions

1.0.7
2.0.5

Description

Versions of converse.js prior to 1.0.7 for 1.x or 2.0.5 for 2.x are vulnerable to User Impersonation. The package provides an incorrect implementation of XEP-0280: Message Carbons that allows a remote attacker to impersonate any user, including contacts, in the vulnerable application's display. This allows for various kinds of social engineering attacks.

Recommendation

If you're using converse.js 1.x, upgrade to 1.0.7 or later.
If you're using converse.js 2.x, upgrade to 2.0.5 or later.

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.
