Overview

CVE-2024-27302 is a critical-severity vulnerability. It was published on March 6, 2024 and has a CVSS 3.1 base score of 9.1 (CRITICAL).

This vulnerability has a CVSS 3.1 base score of 9.1, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

go-zero is a web and rpc framework. Go-zero allows user to specify a CORS Filter with a configurable allows param - which is an array of domains allowed in CORS policy. However, the `isOriginAllowed` uses `strings.HasSuffix` to check the origin, which leads to bypass via a malicious domain. This vulnerability is capable of breaking CORS policy and thus allowing any page to make requests and/or retrieve data on behalf of other users. Version 1.4.4 fixes this issue.

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.
