CVE-2022-38900
Denial of Service vulnerability in decode-uri-component (npm)
What is CVE-2022-38900 About?
The `decode-uri-component` package version 0.2.0 is vulnerable to Improper Input Validation, which can result in a Denial of Service (DoS) condition. By supplying malicious input, an attacker can cause the application to become unresponsive or crash. Exploiting this is likely simple if arbitrary input can be processed.
Affected Software
Technical Details
The vulnerability in decode-uri-component 0.2.0 is due to improper input validation during the decoding of URI components. An attacker can craft a malformed URI component string that, when processed by the vulnerable function, triggers an unexpected state or excessive resource consumption. This could manifest as an infinite loop, excessive memory allocation, or a crash due to an unhandled exception during the decoding process. The lack of robust validation allows the specially crafted input to bypass expected constraints, leading to resource exhaustion and subsequently a Denial of Service for the application utilizing the component.
What is the Impact of CVE-2022-38900?
Successful exploitation may allow attackers to crash the application by providing malformed input, disrupting service availability and leading to a denial of service.
What is the Exploitability of CVE-2022-38900?
Exploitation of this Denial of Service vulnerability is of low complexity, as it primarily involves providing a malformed string to the decode-uri-component function. No specific authentication or elevated privileges are required if the application processes unauthenticated user-supplied URI components. The attack can be remote if the application decodes user-controlled parts of a URL that are accessible over a network. The primary risk factor is the processing of untrusted or unvalidated URI components directly influencing the vulnerable function without proper sanitization or error handling. Applications that decode external URLs or path segments are particularly susceptible.
