Security Advisories 🚨

🚨 Possible Log Injection in Rack::CommonLogger

Summary

Rack::CommonLogger can be exploited by crafting input that includes newline characters to manipulate log entries. The supplied proof-of-concept demonstrates injecting malicious content into logs.

Details

When a user provides the authorization credentials via Rack::Auth::Basic, if success, the username will be put in env['REMOTE_USER'] and later be used by Rack::CommonLogger for logging purposes.

The issue occurs when a server intentionally or unintentionally allows a user creation with the username contain CRLF and white space characters, or the server just want to log every login attempts. If an attacker enters a username with CRLF character, the logger will log the malicious username with CRLF characters into the logfile.

Impact

Attackers can break log formats or insert fraudulent entries, potentially obscuring real activity or injecting malicious data into log files.

Mitigation

Update to the latest version of Rack.

🚨 Rack Header Parsing leads to Possible Denial of Service Vulnerability

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.

Patches

To aid users who aren't able to upgrade immediately we have provided patches for
the two supported release series. They are in git-am format and consist of a
single changeset.

🚨 Rack has possible DoS Vulnerability with Range Header

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.

Patches

To aid users who aren't able to upgrade immediately we have provided patches for
the two supported release series. They are in git-am format and consist of a
single changeset.

3-0-range.patch - Patch for 3.0 series

2-2-range.patch - Patch for 2.2 series

🚨 Rack vulnerable to ReDoS in content type parsing (2nd degree polynomial)

Summary
module Rack
  class MediaType
    SPLIT_PATTERN = %r{\s*[;,]\s*}
The above regexp is subject to ReDos. 50K blank characters as a prefix to the header will take over 10s to split.

PoC

A simple HTTP request with lots of blank characters in the content-type header:
request["Content-Type"] = (" " * 50_000) + "a,"
Impact

It's a very easy to craft ReDoS. Like all ReDoS the impact is debatable.

🚨 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.

🚨 Rack has 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, 3.0.0.1
Impact

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.
Releases

The fixed releases are available at the normal locations.
Workarounds

🚨 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, 2.2.3.1

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.

🚨 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, 2.2.3.1

Impact

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
