Improper Authentication

CVE-2023-39531

Medium
6.8/10

Summary

Sentry is an error tracking and performance monitoring platform. Starting in versions 10.0.0 through 23.7.1, an attacker with sufficient client-side exploits could retrieve a valid access token for another user during the OAuth token exchange due to incorrect credential validation. The client ID must be known and the API application must have already been authorized on the targeted user account. Sentry SaaS customers do not need to take any action. There are no direct workarounds, but users should review applications authorized on their account and remove any that are no longer needed.

CWE-287 - Improper Authentication

Improper (or broken) authentication attacks are widespread, and have accounted for many of the worst data breaches in recent years. Improper authentication attacks are a class of vulnerabilities where an attacker impersonates a legitimate user by exploiting weaknesses in either session management or credential management to gain access to the user’s account. This can result in disclosure of sensitive information, and can lead to system compromise, theft, identity theft, and fraud.
