Summary
CVE-2024-21631 is a vulnerability in Vapor, an HTTP web framework for Swift, affecting versions prior to 4.90.0. The vulnerability is related to the `vapor_urlparser_parse` function, which uses `uint16_t` indexes when parsing a URI's components. This can lead to integer overflows when parsing untrusted inputs, potentially impacting applications that rely on the URI type for validating user input. Attackers can exploit this vulnerability by manipulating the URL authority and tricking the application into accepting a URL to an untrusted destination. The vulnerability has a base score of 6.5, indicating a medium severity level, and an impact score of 3.6, with high integrity impact. Remediation involves updating to version 4 or newer of Vapor to mitigate the issue and ensure secure parsing of URIs.
