CVE-2022-3224
Misinterpretation of Input vulnerability in parse-url (npm)
What is CVE-2022-3224 About?
The `parse-url` package prior to version 8.1.0 is vulnerable to misinterpretation of input, specifically HTTP/HTTPS URLs. It incorrectly identifies some such URLs as SSH protocol or parses hostnames incorrectly. This can lead to unexpected behavior or security bypasses, and exploitation would depend on how the parsed URL is subsequently used.
Affected Software
Technical Details
The parse-url package, in versions before 8.1.0, suffers from a 'Misinterpretation of Input' vulnerability. Specifically, the package's parsing logic for certain http:// or https:// URLs is flawed. This flaw can lead to two primary misinterpretations: (1) the parser might incorrectly identify the URL's protocol as ssh instead of http or https, and (2) it may also incorrectly parse the hostname component of the URL. These misinterpretations could be leveraged by an attacker by providing a specially crafted URL that, when parsed, might bypass security checks expecting an HTTP/HTTPS URL, redirect to an unintended resource, or connect to a malicious SSH endpoint, depending on the application's subsequent usage of the parsed URL components.
What is the Impact of CVE-2022-3224?
Successful exploitation may allow attackers to bypass security checks, redirect users or services to unintended or malicious destinations, or facilitate further attacks by misinterpreting resource locations.
What is the Exploitability of CVE-2022-3224?
Exploitation depends on how the parsed URL is used by the vulnerable application. The complexity is low as it merely requires providing a specially crafted URL string. No authentication or special privileges are needed. The vulnerability is typically remote, as it relies on input provided to an application using parse-url. The key prerequisite is that the application processes URLs using the affected parse-url version and makes security-sensitive decisions based on the parsed components like protocol or hostname. Risk factors increase when parse-url is used in contexts like URL validators, redirect mechanisms, or resource loaders within applications.
