| CVE | Summary | Source | Max CVSS | EPSS % | Published | Updated |
|---|---|---|---|---|---|---|
| CVE-2020-8130 | There is an OS command injection vulnerability in Ruby Rake < 12.3.3 in Rake::FileList when supplying a filename that begins with the pipe character `|`. | [email protected] | 6.4 | 1.42% | 2020-02-24 | 2024-11-21 |
| CVE-2015-1855 | verify_certificate_identity in the OpenSSL extension in Ruby before 2.0.0 patchlevel 645, 2.1.x before 2.1.6, and 2.2.x before 2.2.2 does not properly validate hostnames, which allows remote attackers to spoof servers via vectors related to (1) multiple wildcards, (1) wildcards in IDNA names, (3) case sensitivity, and (4) non-ASCII characters. | [email protected] | 5.9 | 2.81% | 2019-11-29 | 2024-11-21 |
| CVE-2019-16255 | Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x through 2.6.4 allows code injection if the first argument (aka the "command" argument) to Shell#[] or Shell#test in lib/shell.rb is untrusted data. An attacker can exploit this to call an arbitrary Ruby method. | [email protected] | 8.1 | 4.20% | 2019-11-26 | 2024-11-21 |
| CVE-2019-16254 | Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x through 2.6.4 allows HTTP Response Splitting. If a program using WEBrick inserts untrusted input into the response header, an attacker can exploit it to insert a newline character to split a header, and inject malicious content to deceive clients. NOTE: this issue exists because of an incomplete fix for CVE-2017-17742, which addressed the CRLF vector, but did not address an isolated CR or an isolated LF. | [email protected] | 5.3 | 4.45% | 2019-11-26 | 2024-11-21 |
| CVE-2019-16201 | WEBrick::HTTPAuth::DigestAuth in Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x through 2.6.4 has a regular expression Denial of Service cause by looping/backtracking. A victim must expose a WEBrick server that uses DigestAuth to the Internet or a untrusted network. | [email protected] | 7.5 | 4.99% | 2019-11-26 | 2024-11-21 |
| CVE-2019-15845 | Ruby through 2.4.7, 2.5.x through 2.5.6, and 2.6.x through 2.6.4 mishandles path checking within File.fnmatch functions. | [email protected] | 6.5 | 3.23% | 2019-11-26 | 2024-11-21 |
| CVE-2011-4121 | The OpenSSL extension of Ruby (Git trunk) versions after 2011-09-01 up to 2011-11-03 always generated an exponent value of '1' to be used for private RSA key generation. A remote attacker could use this flaw to bypass or corrupt integrity of services, depending on strong private RSA keys generation mechanism. | [email protected] | 9.8 | 2.53% | 2019-11-26 | 2024-11-21 |
| CVE-2011-3624 | Various methods in WEBrick::HTTPRequest in Ruby 1.9.2 and 1.8.7 and earlier do not validate the X-Forwarded-For, X-Forwarded-Host and X-Forwarded-Server headers in requests, which might allow remote attackers to inject arbitrary text into log files or bypass intended address parsing via a crafted header. | [email protected] | 5.3 | 1.52% | 2019-11-26 | 2024-11-21 |
| CVE-2013-1945 | ruby193 uses an insecure LD_LIBRARY_PATH setting. | [email protected] | 3.3 | 0.29% | 2019-10-31 | 2024-11-21 |
| CVE-2019-11879 | The WEBrick gem 1.4.2 for Ruby allows directory traversal if the attacker once had local access to create a symlink to a location outside of the web root directory. NOTE: The vendor states that this is analogous to Options FollowSymlinks in the Apache HTTP Server, and therefore it is "not a problem. | [email protected] | 5.5 | 0.55% | 2019-05-10 | 2024-11-21 |
| CVE-2018-16396 | An issue was discovered in Ruby before 2.3.8, 2.4.x before 2.4.5, 2.5.x before 2.5.2, and 2.6.x before 2.6.0-preview3. It does not taint strings that result from unpacking tainted strings with some formats. | [email protected] | 8.1 | 7.97% | 2018-11-16 | 2024-11-21 |
| CVE-2018-16395 | An issue was discovered in the OpenSSL library in Ruby before 2.3.8, 2.4.x before 2.4.5, 2.5.x before 2.5.2, and 2.6.x before 2.6.0-preview3. When two OpenSSL::X509::Name objects are compared using ==, depending on the ordering, non-equal objects may return true. When the first argument is one character longer than the second, or the second argument contains a character that is one less than a character in the same position of the first argument, the result of == will be true. This could be leve | [email protected] | 9.8 | 10.71% | 2018-11-16 | 2024-11-21 |
| CVE-2018-8780 | In Ruby before 2.2.10, 2.3.x before 2.3.7, 2.4.x before 2.4.4, 2.5.x before 2.5.1, and 2.6.0-preview1, the Dir.open, Dir.new, Dir.entries and Dir.empty? methods do not check NULL characters. When using the corresponding method, unintentional directory traversal may be performed. | [email protected] | 9.1 | 10.10% | 2018-04-03 | 2024-11-21 |
| CVE-2018-8779 | In Ruby before 2.2.10, 2.3.x before 2.3.7, 2.4.x before 2.4.4, 2.5.x before 2.5.1, and 2.6.0-preview1, the UNIXServer.open and UNIXSocket.open methods are not checked for null characters. It may be connected to an unintended socket. | [email protected] | 7.5 | 7.17% | 2018-04-03 | 2024-11-21 |
| CVE-2018-8778 | In Ruby before 2.2.10, 2.3.x before 2.3.7, 2.4.x before 2.4.4, 2.5.x before 2.5.1, and 2.6.0-preview1, an attacker controlling the unpacking format (similar to format string vulnerabilities) can trigger a buffer under-read in the String#unpack method, resulting in a massive and controlled information disclosure. | [email protected] | 7.5 | 7.83% | 2018-04-03 | 2024-11-21 |
| CVE-2018-8777 | In Ruby before 2.2.10, 2.3.x before 2.3.7, 2.4.x before 2.4.4, 2.5.x before 2.5.1, and 2.6.0-preview1, an attacker can pass a large HTTP request with a crafted header to WEBrick server or a crafted body to WEBrick server/handler and cause a denial of service (memory consumption). | [email protected] | 7.5 | 4.64% | 2018-04-03 | 2024-11-21 |
| CVE-2018-6914 | Directory traversal vulnerability in the Dir.mktmpdir method in the tmpdir library in Ruby before 2.2.10, 2.3.x before 2.3.7, 2.4.x before 2.4.4, 2.5.x before 2.5.1, and 2.6.0-preview1 might allow attackers to create arbitrary directories or files via a .. (dot dot) in the prefix argument. | [email protected] | 7.5 | 10.55% | 2018-04-03 | 2024-11-21 |
| CVE-2017-17742 | Ruby before 2.2.10, 2.3.x before 2.3.7, 2.4.x before 2.4.4, 2.5.x before 2.5.1, and 2.6.0-preview1 allows an HTTP Response Splitting attack. An attacker can inject a crafted key and value into an HTTP response for the HTTP server of WEBrick. | [email protected] | 5.3 | 5.76% | 2018-04-03 | 2024-11-21 |
| CVE-2017-17790 | The lazy_initialize function in lib/resolv.rb in Ruby through 2.4.3 uses Kernel#open, which might allow Command Injection attacks, as demonstrated by a Resolv::Hosts::new argument beginning with a '|' character, a different vulnerability than CVE-2017-17405. NOTE: situations with untrusted input may be highly unlikely. | [email protected] | 9.8 | 5.91% | 2017-12-20 | 2026-05-13 |
| CVE-2017-17405 | Ruby before 2.4.3 allows Net::FTP command injection. Net::FTP#get, getbinaryfile, gettextfile, put, putbinaryfile, and puttextfile use Kernel#open to open a local file. If the localfile argument starts with the "|" pipe character, the command following the pipe character is executed. The default value of localfile is File.basename(remotefile), so malicious FTP servers could cause arbitrary command execution. | [email protected] | 8.8 | 73.93% | 2017-12-15 | 2026-05-13 |
