1 CVE-2020-8184 20 2020-06-19 2020-10-05
5.0
None Remote Low Not required None Partial None
A reliance on cookies without validation/integrity check security vulnerability exists in rack < 2.2.3, rack < 2.1.4 that makes it is possible for an attacker to forge a secure or host-only cookie prefix.
2 CVE-2020-8161 22 Dir. Trav. 2020-07-02 2020-10-05
5.0
None Remote Low Not required Partial None None
A directory traversal vulnerability exists in rack < 2.2.0 that allows an attacker perform directory traversal vulnerability in the Rack::Directory app that is bundled with Rack which could result in information disclosure.
3 CVE-2019-16782 203 +Info 2019-12-18 2021-11-02
4.3
None Remote Medium Not required Partial None None
There's a possible information leak / session hijack vulnerability in Rack (RubyGem rack). This vulnerability is patched in versions 1.6.12 and 2.0.8. Attackers may be able to find and hijack sessions by using timing attacks targeting the session id. Session ids are usually stored and indexed in a database that uses some kind of scheme for speeding up lookups of that session id. By carefully measuring the amount of time it takes to look up a session, an attacker may be able to find a valid session id and hijack the session. The session id itself may be generated randomly, but the way the session is indexed by the backing store does not use a secure comparison.
4 CVE-2018-16471 79 XSS Bypass 2018-11-13 2019-06-13
4.3
None Remote Medium Not required None Partial None
There is a possible XSS vulnerability in Rack before 2.0.6 and 1.6.11. Carefully crafted requests can impact the data returned by the `scheme` method on `Rack::Request`. Applications that expect the scheme to be limited to 'http' or 'https' and do not escape the return value could be vulnerable to an XSS attack. Note that applications using the normal escaping mechanisms provided by Rails may not impacted, but applications that bypass the escaping mechanisms, or do not use them may be vulnerable.
5 CVE-2018-16470 400 2018-11-13 2019-10-09
5.0
None Remote Low Not required None None Partial
There is a possible DoS vulnerability in the multipart parser in Rack before 2.0.6. Specially crafted requests can cause the multipart parser to enter a pathological state, causing the parser to use CPU resources disproportionate to the request size.
6 CVE-2015-3225 19 DoS 2015-07-26 2018-10-30
5.0
None Remote Low Not required None None Partial
lib/rack/utils.rb in Rack before 1.5.4 and 1.6.x before 1.6.2, as used with Ruby on Rails 3.x and 4.x and other products, allows remote attackers to cause a denial of service (SystemStackError) via a request with a large parameter depth.
7 CVE-2013-0263 Exec Code +Priv 2013-02-08 2018-08-13
5.1
None Remote High Not required Partial Partial Partial
Rack::Session::Cookie in Rack 1.5.x before 1.5.2, 1.4.x before 1.4.5, 1.3.x before 1.3.10, 1.2.x before 1.2.8, and 1.1.x before 1.1.6 allows remote attackers to guess the session cookie, gain privileges, and execute arbitrary code via a timing attack involving an HMAC comparison function that does not run in constant time.
8 CVE-2013-0262 22 Dir. Trav. 2013-02-08 2018-08-13
4.3
None Remote Medium Not required Partial None None
rack/file.rb (Rack::File) in Rack 1.5.x before 1.5.2 and 1.4.x before 1.4.5 allows attackers to access arbitrary files outside the intended root directory via a crafted PATH_INFO environment variable, probably a directory traversal vulnerability that is remotely exploitable, aka "symlink path traversals."
9 CVE-2013-0184 DoS 2013-03-01 2013-10-31
4.3
None Remote Medium Not required None None Partial
Unspecified vulnerability in Rack::Auth::AbstractRequest in Rack 1.1.x before 1.1.5, 1.2.x before 1.2.7, 1.3.x before 1.3.9, and 1.4.x before 1.4.4 allows remote attackers to cause a denial of service via unknown vectors related to "symbolized arbitrary strings."
10 CVE-2013-0183 119 DoS Overflow 2013-03-01 2018-08-13
5.0
None Remote Low Not required None None Partial
multipart/parser.rb in Rack 1.3.x before 1.3.8 and 1.4.x before 1.4.3 allows remote attackers to cause a denial of service (memory consumption and out-of-memory error) via a long string in a Multipart HTTP packet.
11 CVE-2012-6109 DoS 2013-03-01 2018-08-13
4.3
None Remote Medium Not required None None Partial
lib/rack/multipart.rb in Rack before 1.1.4, 1.2.x before 1.2.6, 1.3.x before 1.3.7, and 1.4.x before 1.4.2 uses an incorrect regular expression, which allows remote attackers to cause a denial of service (infinite loop) via a crafted Content-Disposion header.
12 CVE-2011-5036 310 DoS 2011-12-30 2013-10-31
5.0
None Remote Low Not required None None Partial
Rack before 1.1.3, 1.2.x before 1.2.5, and 1.3.x before 1.3.6 computes hash values for form parameters without restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service (CPU consumption) by sending many crafted parameters.
