Security Advisories 🚨
🚨 Denial of Service Vulnerability in Rack Content-Type Parsing
There is a possible denial of service vulnerability in the content type
parsing component of Rack. This vulnerability has been assigned the CVE
identifier CVE-2024-25126.Versions Affected: >= 0.4 Not affected: < 0.4 Fixed Versions: 3.0.9.1, 2.2.8.1
Impact
Carefully crafted content type headers can cause Rack’s media type parser to
take much longer than expected, leading to a possible denial of service
vulnerability.Impacted code will use Rack’s media type parser to parse content type headers.
This code will look like below:request.media_type OR request.media_type_params OR Rack::MediaType.type(content_type)
Some frameworks (including Rails) call this code internally, so upgrading is
recommended!All users running an affected release should either upgrade or use one of the
workarounds immediately.Releases
The fixed releases are available at the normal locations.
Workarounds
There are no feasible workarounds for this issue.
🚨 Possible DoS Vulnerability with Range Header in Rack
There is a possible DoS vulnerability relating to the Range request header in
Rack. This vulnerability has been assigned the CVE identifier CVE-2024-26141.Versions Affected: >= 1.3.0. Not affected: < 1.3.0 Fixed Versions: 3.0.9.1, 2.2.8.1
Impact
Carefully crafted Range headers can cause a server to respond with an
unexpectedly large response. Responding with such large responses could lead
to a denial of service issue.Vulnerable applications will use the
Rack::File
middleware or the
Rack::Utils.byte_ranges
methods (this includes Rails applications).Releases
The fixed releases are available at the normal locations.
Workarounds
There are no feasible workarounds for this issue.
🚨 Possible Denial of Service Vulnerability in Rack Header Parsing
There is a possible denial of service vulnerability in the header parsing
routines in Rack. This vulnerability has been assigned the CVE identifier
CVE-2024-26146.Versions Affected: All. Not affected: None Fixed Versions: 2.0.9.4, 2.1.4.4, 2.2.8.1, 3.0.9.1
Impact
Carefully crafted headers can cause header parsing in Rack to take longer than
expected resulting in a possible denial of service issue.Accept
and
Forwarded
headers are impacted.Ruby 3.2 has mitigations for this problem, so Rack applications using
Ruby 3.2 or newer are unaffected.Releases
The fixed releases are available at the normal locations.
Workarounds
There are no feasible workarounds for this issue.
🚨 Possible Denial of Service Vulnerability in Rack’s header parsing
There is a denial of service vulnerability in the header parsing component of Rack. This vulnerability has been assigned the CVE identifier CVE-2023-27539.
Versions Affected: >= 2.0.0 Not affected: None. Fixed Versions: 2.2.6.4, 3.0.6.1
Impact
Carefully crafted input can cause header parsing in Rack to take an unexpected amount of time, possibly resulting in a denial of service attack vector. Any applications that parse headers using Rack (virtually all Rails applications) are impacted.
Workarounds
Setting Regexp.timeout in Ruby 3.2 is a possible workaround.
🚨 Possible DoS Vulnerability in Multipart MIME parsing
There is a possible DoS vulnerability in the Multipart MIME parsing code in Rack. This vulnerability has been assigned the CVE identifier CVE-2023-27530.
Versions Affected: All. Not affected: None Fixed Versions: 3.0.4.2, 2.2.6.3, 2.1.4.3, 2.0.9.3
Impact
The Multipart MIME parsing code in Rack limits the number of file parts, but does not limit the total number of parts that can be uploaded. Carefully crafted requests can abuse this and cause multipart parsing to take longer than expected.
All users running an affected release should either upgrade or use one of the workarounds immediately.
Workarounds
A proxy can be configured to limit the POST body size which will mitigate this issue.
🚨 Denial of service via header parsing in Rack
There is a possible denial of service vulnerability in the Range header
parsing component of Rack. This vulnerability has been assigned the CVE
identifier CVE-2022-44570.Versions Affected: >= 1.5.0
Not affected: None.
Fixed Versions: 2.0.9.2, 2.1.4.2, 2.2.6.2, 3.0.4.1Impact
Carefully crafted input can cause the Range header parsing component in Rack
to take an unexpected amount of time, possibly resulting in a denial of
service attack vector. Any applications that deal with Range requests (such
as streaming applications, or applications that serve files) may be impacted.Workarounds
There are no feasible workarounds for this issue.
🚨 Denial of service via multipart parsing in Rack
There is a denial of service vulnerability in the multipart parsing component
of Rack. This vulnerability has been assigned the CVE identifier
CVE-2022-44572.Versions Affected: >= 2.0.0
Not affected: None.
Fixed Versions: 2.0.9.2, 2.1.4.2, 2.2.6.1, 3.0.4.1Impact
Carefully crafted input can cause RFC2183 multipart boundary parsing in Rack
to take an unexpected amount of time, possibly resulting in a denial of
service attack vector. Any applications that parse multipart posts using
Rack (virtually all Rails applications) are impacted.Workarounds
There are no feasible workarounds for this issue.
🚨 Denial of Service Vulnerability in Rack Content-Disposition parsing
There is a denial of service vulnerability in the Content-Disposition parsing
component of Rack. This vulnerability has been assigned the CVE identifier
CVE-2022-44571.Versions Affected: >= 2.0.0
Not affected: None.
Fixed Versions: 2.0.9.2, 2.1.4.2, 2.2.6.1, 3.0.4.1Impact
Carefully crafted input can cause Content-Disposition header parsing in Rack
to take an unexpected amount of time, possibly resulting in a denial of
service attack vector. This header is used typically used in multipart
parsing. Any applications that parse multipart posts using Rack (virtually
all Rails applications) are impacted.Workarounds
There are no feasible workarounds for this issue.
🚨 Denial of Service Vulnerability in Rack Multipart Parsing
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, 2.2.3.1Impact
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.
🚨 Possible shell escape sequence injection vulnerability in Rack
There is a possible shell escape sequence injection vulnerability in the Lint
and CommonLogger components of Rack. This vulnerability has been assigned the
CVE identifier CVE-2022-30123.Versions Affected: All.
Not affected: None
Fixed Versions: 2.0.9.1, 2.1.4.1, 2.2.3.1Impact
Carefully crafted requests can cause shell escape sequences to be written to
the terminal via Rack's Lint middleware and CommonLogger middleware. These
escape sequences can be leveraged to possibly execute commands in the victim's
terminal.Impacted applications will have either of these middleware installed, and
vulnerable apps may have something like this:use Rack::Lint
Or
use Rack::CommonLogger
All users running an affected release should either upgrade or use one of the
workarounds immediately.Workarounds
Remove these middleware from your application
