https://notcve.org/view.php?id=CVE-2021-32066
21 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. Net::IMAP does not raise an exception when StartTLS fails with an an unknown response, which might allow man-in-the-middle attackers to bypass the TLS protections by leveraging a network position between the client and the registry to block the StartTLS command, aka a "StartTLS stripping attack."

CVE-2021-31810 – ruby: FTP PASV command response can cause Net::FTP to connect to arbitrary host
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).

CVE-2021-21409 – Possible request smuggling in HTTP/2 due missing validation of content-length
https://notcve.org/view.php?id=CVE-2021-21409
30 Mar 2021 — Netty is an open-source, asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. In Netty (io.netty:netty-codec-http2) before version 4.1.61.Final there is a vulnerability that enables request smuggling. The content-length header is not correctly validated if the request only uses a single Http2HeaderFrame with the endStream set to to true. This could lead to request smuggling if the request is proxied to a remote peer and tr... • https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-21295 • CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •

CVE-2021-3450 – CA certificate check bypass with X509_V_FLAG_X509_STRICT
https://notcve.org/view.php?id=CVE-2021-3450
25 Mar 2021 — The X509_V_FLAG_X509_STRICT flag enables additional security checks of the certificates present in a certificate chain. It is not set by default. Starting from OpenSSL version 1.1.1h a check to disallow certificates in the chain that have explicitly encoded elliptic curve parameters was added as an additional strict check. An error in the implementation of this check meant that the result of a previous check to confirm that certificates in the chain are valid CA certificates was overwritten.

CVE-2021-3449 – NULL pointer deref in signature_algorithms processing
https://notcve.org/view.php?id=CVE-2021-3449
25 Mar 2021 — An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signature_algorithms extension (where it was present in the initial ClientHello), but includes a signature_algorithms_cert extension then a NULL pointer dereference will result, leading to a crash and a denial of service attack. A server is only vulnerable if it has TLSv1.2 and renegotiation enabled (which is the default configuration). OpenSSL TLS c... • https://github.com/riptl/cve-2021-3449 • CWE-476: NULL Pointer Dereference •

CVE-2021-22884 – nodejs: DNS rebinding in --inspect
https://notcve.org/view.php?id=CVE-2021-22884
28 Feb 2021 — Node.js before 10.24.0, 12.21.0, 14.16.0, and 15.10.0 is vulnerable to DNS rebinding attacks as the whitelist includes “localhost6”. When “localhost6” is not present in /etc/hosts, it is just an ordinary domain that is resolved via DNS, i.e., over network. If the attacker controls the victim's DNS server or can spoof its responses, the DNS rebinding protection can be bypassed by using the “localhost6” domain. As long as the attacker uses the “localhost6” domain, they can still apply the attack described in ... • https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf • CWE-20: Improper Input Validation CWE-350: Reliance on Reverse DNS Resolution for a Security-Critical Action •
