CVE-2022-39288
HIGH7.5EPSS 5.9%fastify vulnerable to denial of service via malicious Content-Type
描述
### Impact An attacker can send an invalid `Content-Type` header that can cause the application to crash, leading to a possible Denial of Service attack. Only the v4.x line is affected. (This was updated: upon a close inspection, v3.x is not affected after all). ### Patches Yes, update to `> v4.8.0`. ### Workarounds You can reject the malicious content types before the body parser enters in action. ```js const badNames = Object.getOwnPropertyNames({}.__proto__) fastify.addHook('onRequest', async (req, reply) => { for (const badName of badNames) { if (req.headers['content-type'].indexOf(badName) > -1) { reply.code(415) throw new Error('Content type not supported') } } }) ``` ### References See the HackerOne report [#1715536](https://hackerone.com/bugs?report_id=1715536&subject=fastify) ### For more information [Fastify security policy](https://github.com/fastify/fastify/security/policy)
