https://notcve.org/view.php?id=CVE-2021-31810
13 Jul 2021 — An issue was discovered in Ruby through 2.6.7, 2.7.x through 2.7.3, and 3.x through 3.0.1. A malicious FTP server can use the PASV response to trick Net::FTP into connecting back to a given IP address and port. This potentially makes curl extract information about services that are otherwise private and not disclosed (e.g., the attacker can conduct port scans and service banner extractions). Se ha detectado un problema en Ruby versiones hasta 2.6.7, versiones 2.7.x hasta 2.7.3, y versiones 3.x hasta 3.0.1. ... • https://hackerone.com/reports/1145454 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

CVE-2021-28965 – ruby: XML round-trip vulnerability in REXML
https://notcve.org/view.php?id=CVE-2021-28965
21 Apr 2021 — The REXML gem before 3.2.5 in Ruby before 2.6.7, 2.7.x before 2.7.3, and 3.x before 3.0.1 does not properly address XML round-trip issues. An incorrect document can be produced after parsing and serializing. El REXML gem versiones anteriores a 3.2.5 en Ruby versiones anteriores a 2.6.7, versiones 2.7.x anteriores a 2.7.3 y versiones 3.x anteriores a 3.0.1, no aborda apropiadamente los problemas round-trip de XML.

CVE-2020-25613 – ruby: Potential HTTP request smuggling in WEBrick
https://notcve.org/view.php?id=CVE-2020-25613
06 Oct 2020 — An issue was discovered in Ruby through 2.5.8, 2.6.x through 2.6.6, and 2.7.x through 2.7.1. WEBrick, a simple HTTP server bundled with Ruby, had not checked the transfer-encoding header value rigorously. An attacker may potentially exploit this issue to bypass a reverse proxy (which also has a poor header check), which may lead to an HTTP Request Smuggling attack. Se detectó un problema en Ruby versiones hasta 2.5.8, versiones 2.6.x hasta 2.6.6 y versiones 2.7.x hasta 2.7.1.

CVE-2020-10933 – ruby: BasicSocket#read_nonblock method leads to information disclosure
https://notcve.org/view.php?id=CVE-2020-10933
04 May 2020 — An issue was discovered in Ruby 2.5.x through 2.5.7, 2.6.x through 2.6.5, and 2.7.0. If a victim calls BasicSocket#read_nonblock(requested_size, buffer, exception: false), the method resizes the buffer to fit the requested size, but no data is copied. Thus, the buffer string provides the previous value of the heap. This may expose possibly sensitive data from the interpreter.

CVE-2020-5247 – HTTP Response Splitting in Puma
https://notcve.org/view.php?id=CVE-2020-5247
28 Feb 2020 — In Puma (RubyGem) before 4.3.2 and before 3.12.3, if an application using Puma allows untrusted input in a response header, an attacker can use newline characters (i.e. `CR`, `LF` or`/r`, `/n`) to end the header and inject malicious content, such as additional headers or an entirely new response body. This vulnerability is known as HTTP Response Splitting. While not an attack in itself, response splitting is a vector for several other attacks, such as cross-site scripting (XSS). This is related to CVE-2019-... • https://github.com/puma/puma/security/advisories/GHSA-84j7-475p-hp8v • CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') CWE-113: Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Request/Response Splitting') •
