No affected components available
Summary
The request body parsing in starlite allows a potentially unauthenticated
attacker to consume a large amount of CPU time and RAM.
Details
The multipart body parser processes an unlimited number of file parts. The multipart body parser processes an unlimited number of field parts.
Impact
This is a remote, potentially unauthenticated Denial of Service vulnerability.
This vulnerability affects applications with a request handler that accepts
a Body(media_type=RequestEncodingType.MULTI_PART).
The large amount of CPU time required for processing requests can block all available worker processes and significantly delay or slow down the processing of legitimate user requests. The large amount of RAM accumulated while processing requests can lead to Out-Of-Memory kills. Complete DoS is achievable by sending many concurrent multipart requests in a loop.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker does not need any special privileges or access rights. No user interaction is needed for the attacker to exploit this vulnerability. The impact is confined to the system where the vulnerability exists. There is a high impact on the availability of the system.
Exploitation attempts have been detected. Elevated vigilance and prompt remediation are advised.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
