CVE-2021-20156 1 Trendnet 2 Tew-827dru, Tew-827dru Firmware 2022-01-07 4.0 MEDIUM 6.5 MEDIUM
Trendnet AC2600 TEW-827DRU version 2.08B01 contains an improper access control configuration that could allow for a malicious firmware update. It is possible to manually install firmware that may be malicious in nature as there does not appear to be any signature validation done to determine if it is from a known and trusted source. This includes firmware updates that are done via the automated "check for updates" in the admin interface. If an attacker is able to masquerade as the update server, the device will not verify that the firmware updates downloaded are legitimate.
CVE-2020-10126 1 Ncr 2 Aptra Xfs, Selfserv Atm 2021-12-20 7.2 HIGH 7.6 HIGH
NCR SelfServ ATMs running APTRA XFS 05.01.00 do not properly validate softare updates for the bunch note acceptor (BNA), enabling an attacker with physical access to internal ATM components to restart the host computer and execute arbitrary code with SYSTEM privileges because while booting, the update process looks for CAB archives on removable media and executes a specific file without first validating the signature of the CAB archive.
CVE-2021-34420 1 Zoom 1 Zoom Client For Meetings 2021-12-16 4.3 MEDIUM 7.4 HIGH
The Zoom Client for Meetings for Windows installer before version 5.5.4 does not properly verify the signature of files with .msi, .ps1, and .bat extensions. This could lead to a malicious actor installing malicious software on a customer’s computer.
CVE-2021-0152 1 Intel 30 Ac1550, Ac1550 Firmware, Ac 3165 and 27 more 2021-11-23 2.1 LOW 5.5 MEDIUM
Improper verification of cryptographic signature in the installer for some Intel(R) Wireless Bluetooth(R) and Killer(TM) Bluetooth(R) products in Windows 10 may allow an authenticated user to potentially enable denial of service via local access.
CVE-2020-15240 1 Auth0 1 Omniauth-auth0 2021-11-18 5.8 MEDIUM 9.1 CRITICAL
omniauth-auth0 (rubygems) versions >= 2.3.0 and < 2.4.1 improperly validate the JWT token signature when using the `jwt_validator.verify` method. Improper validation of the JWT token signature can allow an attacker to bypass authentication and authorization. You are affected by this vulnerability if all of the following conditions apply: 1. You are using `omniauth-auth0`. 2. You are using `JWTValidator.verify` method directly OR you are not authenticating using the SDK’s default Authorization Code Flow. The issue is patched in version 2.4.1.

The verify function in the Stark Bank Node.js ECDSA library (ecdsa-node) 1.1.2 fails to check that the signature is non-zero, which allows attackers to forge signatures on arbitrary messages.
CVE-2021-43570 1 Starkbank 1 Ecdsa-java 2021-11-12 7.5 HIGH 9.8 CRITICAL
The verify function in the Stark Bank Java ECDSA library (ecdsa-java) 1.0.0 fails to check that the signature is non-zero, which allows attackers to forge signatures on arbitrary messages.
CVE-2021-37127 1 Huawei 4 Imanager Neteco, Imanager Neteco 6000, Imanager Neteco 6000 Firmware and 1 more 2021-10-28 9.0 HIGH 7.2 HIGH
There is a signature management vulnerability in some huawei products. An attacker can forge signature and bypass the signature check. During firmware update process, successful exploit this vulnerability can cause the forged system file overwrite the correct system file.

CVE-2020-15093 1 Amazon 1 Tough 2021-10-26 5.0 MEDIUM 8.6 HIGH
The tough library (Rust/crates.io) prior to version 0.7.1 does not properly verify the threshold of cryptographic signatures. It allows an attacker to duplicate a valid signature in order to circumvent TUF requiring a minimum threshold of unique signatures before the metadata is considered valid. A fix is available in version 0.7.1. CVE-2020-6174 is assigned to the same vulnerability in the TUF reference implementation.
CVE-2021-1849 1 Apple 5 Ipados, Iphone Os, Macos and 2 more 2021-09-20 5.0 MEDIUM 7.5 HIGH
An issue in code signature validation was addressed with improved checks. This issue is fixed in macOS Big Sur 11.3, iOS 14.5 and iPadOS 14.5, watchOS 7.4, tvOS 14.5. A malicious application may be able to bypass Privacy preferences.
CVE-2021-3051 1 Paloaltonetworks 1 Cortex Xsoar 2021-09-17 6.8 MEDIUM 8.1 HIGH

CVE-2020-26540 2 Apple, Foxitsoftware 3 Macos, Foxit Reader, Phantompdf 2021-09-08 5.0 MEDIUM 7.5 HIGH
An issue was discovered in Foxit Reader and PhantomPDF before 4.1 on macOS. Because the Hardened Runtime protection mechanism is not applied to code signing, code injection (or an information leak) can occur.
CVE-2021-34433 1 Eclipse 1 Californium 2021-08-26 5.0 MEDIUM 7.5 HIGH
In Eclipse Californium version 2.0.0 to 2.6.4 and 3.0.0-M1 to 3.0.0-M3, the certificate based (x509 and RPK) DTLS handshakes accidentally succeeds without verifying the server side's signature on the client side, if that signature is not included in the server's ServerKeyExchange.
CVE-2021-38195 1 Parity 1 Libsecp256k1 2021-08-16 7.5 HIGH 9.8 CRITICAL
An issue was discovered in the libsecp256k1 crate before 0.5.0 for Rust. It can verify an invalid signature because it allows the R or S parameter to be larger than the curve order, aka an overflow.
CVE-2019-14859 2 Python-ecdsa Project, Redhat 4 Python-ecdsa, Ceph Storage, Openstack and 1 more 2021-08-04 6.4 MEDIUM 9.1 CRITICAL
A flaw was found in all python-ecdsa versions before 0.13.3, where it did not correctly verify whether signatures used DER encoding. Without this verification, a malformed signature could be accepted, making the signature malleable. Without proper verification, an attacker could use a malleable signature to create false transactions.
