  • GHSA-hxqx-xwvh-44m2Denial of Service Vulnerability in Rack Multipart Parsing2022-05-27ghsa · osvUS

    There is a possible denial of service vulnerability in the multipart parsing component of Rack. This vulnerability has been assigned the CVE identifier CVE-2022-30122. Versions Affected: >= 1.2 Not affected: < 1.2 Fixed Versions: 2.0.9.1, 2.1.4.1, 2.2.3.1 ## Impact Carefully crafted multipart POST requests can cause Rack's multipart parser to take much longer than expected, leading to a possible denial of service vulnerability. Impacted code will use Rack's multipart parser to parse multipart posts. This includes directly using the multipart parser like this: ``` params = Rack::Multipart.parse_multipart(env) ``` But it also includes reading POST data from a Rack request object like this: ``` p request.POST # read POST data p request.params # reads both query params and POST data ``` All users running an affected release should either upgrade or use one of the workarounds immediately. ## Workarounds There are no feasible workarounds for this issue.
