CVE-2023-26451

7.5 · HIGH

Functions with insufficient randomness were used to generate authorization tokens of the integrated oAuth Authorization Service.

Published Aug 2, 2023CWE-330EPSS 1.19%

Overview

CVE-2023-26451 is a high-severity vulnerability. It was published on August 2, 2023 and has a CVSS 3.1 base score of 7.5 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

Functions with insufficient randomness were used to generate authorization tokens of the integrated oAuth Authorization Service. Authorization codes were predictable for third parties and could be used to intercept and take over the client authorization process. As a result, other users accounts could be compromised. The oAuth Authorization Service is not enabled by default. We have updated the implementation to use sources with sufficient randomness to generate authorization tokens. No publicly available exploits are known.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
