Detailsinfo

A vulnerability was found in vercel next.js up to 13.5.7/14.2.20/15.1.1 and classified as problematic. Affected by this issue is an unknown part of the component HTTP Request Handler. The manipulation with an unknown input leads to a allocation of resources vulnerability. Using CWE to declare the problem leads to CWE-770. The product allocates a reusable resource or group of resources on behalf of an actor without imposing any restrictions on the size or number of resources that can be allocated, in violation of the intended security policy for that actor. Impacted is availability. CVE summarizes:

Next.js is a React framework for building full-stack web applications. Starting in version 13.0.0 and prior to versions 13.5.8, 14.2.21, and 15.1.2, Next.js is vulnerable to a Denial of Service (DoS) attack that allows attackers to construct requests that leaves requests to Server Actions hanging until the hosting provider cancels the function execution. This vulnerability can also be used as a Denial of Wallet (DoW) attack when deployed in providers billing by response times. (Note: Next.js server is idle during that time and only keeps the connection open. CPU and memory footprint are low during that time.). Deployments without any protection against long running Server Action invocations are especially vulnerable. Hosting providers like Vercel or Netlify set a default maximum duration on function execution to reduce the risk of excessive billing. This is the same issue as if the incoming HTTP request has an invalid `Content-Length` header or never closes. If the host has no other mitigations to those then this vulnerability is novel. This vulnerability affects only Next.js deployments using Server Actions. The issue was resolved in Next.js 13.5.8, 14.2.21, and 15.1.2. We recommend that users upgrade to a safe version. There are no official workarounds.

The advisory is available at github.com. This vulnerability is handled as CVE-2024-56332 since 12/19/2024. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1499 by the MITRE ATT&CK project.

Upgrading to version 13.5.8, 14.2.21 or 15.1.2 eliminates this vulnerability.
