CVE-2024-12797 RFC7250 handshakes with unauthenticated servers don't abort as expected

Issue summary: Clients using RFC7250 Raw Public Keys RPKs to authenticate a server may fail to notice that the server was not authenticated, because handshakes don't abort as expected when the SSLVERIFYPEER verification mode is set. Impact summary: TLS and DTLS connections using raw public keys m...

CVE-2024-12797

A flaw was found in OpenSSL's RFC7250 Raw Public Key RPK authentication. This vulnerability allows man-in-the-middle MITM attacks via failure to abort TLS/DTLS handshakes when the server's RPK does not match the expected key despite the SSLVERIFYPEER verification mode being set. Mitigation...

PT-2025-6245

Name of the Vulnerable Software and Affected Versions OpenSSL versions 3.2 through 3.4 Description The issue arises when TLS clients explicitly enable the use of Raw Public Keys RPKs by the server, and the server enables sending of an RPK instead of an X.509 certificate chain. Clients that rely o...

ALPINE-CVE-2024-12243

A flaw was found in GnuTLS, which relies on libtasn1 for ASN.1 data processing. Due to an inefficient algorithm in libtasn1, decoding certain DER-encoded certificate data can take excessive time, leading to increased resource consumption. This flaw allows a remote attacker to send a specially...

Azure Linux 3.0 Security Update: cmake / curl (CVE-2024-2466)

The version of cmake / curl installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-2466 advisory. - libcurl did not check the server certificate of TLS connections done to a host specified as an IP...

Azure Linux 3.0 Security Update: mariadb (CVE-2023-6937)

The version of mariadb installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2023-6937 advisory. - wolfSSL prior to 5.6.6 did not check that messages in one DTLS record do not span key boundaries. As a resul...

Azure Linux 3.0 Security Update: python3 (CVE-2024-0397)

The version of python3 installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-0397 advisory. - A defect was discovered in the Python ssl module where there is a memory race condition with the...

The version of golang installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-9355 advisory. - A vulnerability was found in Golang FIPS OpenSSL. This flaw allows a malicious user to randomly cause an...

Azure Linux 3.0 Security Update: cloud-hypervisor-cvm / edk2 / hvloader / nodejs / nodejs18 / openssl (CVE-2024-2511)

The version of cloud-hypervisor-cvm / edk2 / hvloader / nodejs / nodejs18 / openssl installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2024-2511 advisory. - Issue summary: Some non-default TLS server...

Authentication Bypass

NGINX is vulnerable to Authentication Bypass. The vulnerability is due to shared TLS session states due to the use of TLS Session Tickets and/or the SSL session cache in the default server, which performs client certificate authentication. Attackers can use session resumption to bypass...

curl: TLS Cipher Misconfiguration in HTTP/3/QUIC Support

Summary: This vulnerability occurs when the --ciphers option is used with the curl command to manually specify TLS cipher suites. HTTP/3 or QUIC fails to function in this scenario because QUIC does not rely on traditional TLS cipher suites defined for TLS 1.2 or earlier. Consequently, using the...

CVE-2025-23419

A flaw was found in nginx. When name-based virtual hosts are configured to share the same IP address and port combination with TLS 1.3 and OpenSSL, a previously authenticated attacker can use session resumption to bypass client certificate authentication requirements on these servers. This...

BIT-NGINX-2025-23419 TLS Session Resumption Vulnerability

When multiple server blocks are configured to share the same IP address and port, an attacker can use session resumption to bypass client certificate authentication requirements on these servers. This vulnerability arises when TLS Session Tickets...

CVE-2025-23217 Mitmweb API Authentication Bypass Using Proxy Server

mitmproxy is a interactive TLS-capable intercepting HTTP proxy for penetration testers and software developers and mitmweb is a web-based interface for mitmproxy.

Internet Bug Bounty: TLS client authentication can be bypassed due to ticket resumption

The TLS client authentication can be bypassed due to ticket resumption. The issue was that TLS session tickets were not properly isolated for multiple virtual hosts in one server. This allowed a ticket issued for one virtual host to be resumed at a different virtual host, circumventing client...
