CVE-ID: CVE-2024-38428

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to improper input validation of URL when parsing strings with semicolons within the scheme_leading_string() function in url.c. A remote attacker can pass a specially crafted URL to the application and influence its behavior in which data that was supposed to be in the userinfo subcomponent is misinterpreted to be part of the host subcomponent.

Mitigation

Install updates from vendor's repository.
