Title
OpenSSL partial chain store policy bypass
Summary
When doing TLS related transfers with reused easy or multi handles and
altering the `CURLSSLOPT_NO_PARTIALCHAIN` option, libcurl could accidentally
reuse a CA store cached in memory for which the partial chain option was
reversed. Contrary to the user's wishes and expectations. This could make
libcurl find and accept a trust chain that it otherwise would not.

Title
An improper certificates validation vulnerability was found in the Notification settings of ADM
Summary
When the user set the Notification's sender to send emails to the SMTP server via msmtp, an improper validated TLS/SSL certificates allows an attacker who can intercept network traffic between the SMTP client and server to execute a man-in-the-middle (MITM) attack, which may obtain the sensitive information of the SMTP.
Affected products and versions include: from ADM 4.1.0 through ADM 4.3.3.RKD2 as well as from ADM 5.0.0 through ADM 5.1.0.RN42.

Title
No QUIC certificate pinning with GnuTLS
Summary
When using `CURLOPT_PINNEDPUBLICKEY` option with libcurl or `--pinnedpubkey`
with the curl tool, curl should check the public key of the server certificate
to verify the peer.
This check was skipped in a certain condition that would then make curl allow
the connection without performing the proper check, thus not noticing a
possible impostor. To skip this check, the connection had to be done with QUIC
with ngtcp2 built to use GnuTLS and the user had to explicitly disable the
standard certificate verification.

Title
Improper certificate validation in firmware update logic in NETGEAR RAX30 and RAXE300
Summary
Improper certificate
validation in firmware update logic in NETGEAR RAX30 (Nighthawk AX5 5-Stream
AX2400 WiFi 6 Router) and RAXE300 (Nighthawk AXE7800 Tri-Band
WiFi 6E Router) allows attackers with the ability to intercept and
tamper traffic destined to the device to execute arbitrary commands on the
device.
Devices
with automatic updates enabled may already have this patch applied. If not,
please check the firmware version and update to the
latest.
Fixed in:
RAX30 firmware
1.0.14.108 or later.
RAXE300 firmware
1.0.9.82 or later

Title
Improper Certificate Validation May Allow Successful TLS Handshaking Despite Invalid Extended Key Usage Fields in MongoDB Server
Summary
Clients may successfully perform a TLS handshake with a MongoDB server despite presenting a client certificate not aligning with the documented Extended Key Usage (EKU) requirements. A certificate that specifies extendedKeyUsage but is missing extendedKeyUsage = clientAuth may still be successfully authenticated via the TLS handshake as a client. This issue is specific to MongoDB servers running on Windows or Apple as the expected validation behavior functions correctly on Linux systems.
Additionally, MongoDB servers may successfully establish egress TLS connections with servers that present server certificates not aligning with the documented Extended Key Usage (EKU) requirements. A certificate that specifies extendedKeyUsage but is missing extendedKeyUsage = serverAuth may still be successfully authenticated via the TLS handshake as a server. This issue is specific to MongoDB servers running on Apple as the expected validation behavior functions correctly on both Linux and Windows systems.
This vulnerability affects MongoDB Server v7.0 versions prior to 7.0.26, MongoDB Server v8.0 versions prior to 8.0.16 and MongoDB Server v8.2 versions prior to 8.2.2

Title
Tomofun Furbo 360/Furbo Mini HTTP Traffic collect_logs.sh upload_file_to_s3 certificate validation
Summary
A vulnerability was identified in Tomofun Furbo 360 and Furbo Mini. Affected by this issue is the function upload_file_to_s3 of the file collect_logs.sh of the component HTTP Traffic Handler. The manipulation leads to improper certificate validation. The attack may be initiated remotely. The attack is considered to have high complexity. The exploitation is known to be difficult. The firmware versions determined to be affected are Furbo 360 up to FB0035_FW_036 and Furbo Mini up to MC0020_FW_074. The vendor was contacted early about this disclosure but did not respond in any way.

Mitigation
Architecture and Design
Implementation
Certificates should be carefully managed and checked to assure that data are encrypted with the intended owner's public key.
Mitigation
Implementation
If certificate pinning is being used, ensure that all relevant properties of the certificate are fully validated before the certificate is pinned, including the hostname.
CAPEC-459: Creating a Rogue Certification Authority Certificate
An adversary exploits a weakness resulting from using a hashing algorithm with weak collision resistance to generate certificate signing requests (CSR) that contain collision blocks in their "to be signed" parts. The adversary submits one CSR to be signed by a trusted certificate authority then uses the signed blob to make a second certificate appear signed by said certificate authority. Due to the hash collision, both certificates, though different, hash to the same value and so the signed blob works just as well in the second certificate. The net effect is that the adversary's second X.509 certificate, which the Certification Authority has never seen, is now signed and validated by that Certification Authority.
CAPEC-475: Signature Spoofing by Improper Validation
An adversary exploits a cryptographic weakness in the signature verification algorithm implementation to generate a valid signature without knowing the key.
