GSD-2022-30122

Vulnerability from gsd - Updated: 2022-06-27 00:00

Details

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.

Vulnerability from github – Published: 2022-05-27 16:36 – Updated: 2023-08-28 13:59

Summary

Denial of Service Vulnerability in Rack Multipart Parsing

Details

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.

Severity

7.5 (High)
