How to Fix CVE-2024-45258

To remediate this vulnerability, upgrade all affected Github.com/imroc/req/v3 dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/imroc/req/v3 fixed: 3.43.4 
Upgrade github.com/imroc/req/v3 to 3.43.4
github.com/imroc/req fixed: 3.43.4 
Upgrade github.com/imroc/req to 3.43.4
github.com/imroc/req/v2 fixed: 3.43.4 
Upgrade github.com/imroc/req/v2 to 3.43.4
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/imroc/req/v3

How to Check if You Are Affected

To determine whether your application is affected by CVE-2024-45258, inspect your project dependencies for Github.com/imroc/req/v3:

inspect dependencies for github.com/imroc/req/v3

Analyze the terminal output to locate any version of Github.com/imroc/req/v3 in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.43.4), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In Github.com/imroc/req/v3, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

The `req` library is a widely used HTTP library in Go. However, it does not handle malformed URLs effectively. As a result, after parsing a malformed URL, the library may send HTTP requests to unexpected destinations, potentially leading to security vulnerabilities or unintended behavior in applications relying on this library for handling HTTP requests. Despite developers potentially utilizing the `net/url` library to parse malformed URLs and implement blocklists to prevent HTTP requests to listed URLs, inconsistencies exist between how the `net/url` and `req` libraries parse URLs. These discrepancies can lead to the failure of defensive strategies, resulting in potential security threats such as Server-Side Request Forgery (SSRF) and Remote Code Execution (RCE).
