CVE-2020-26541 2 Linux, Redhat 4 Linux Kernel, Enterprise Linux, Rhel Eus and 1 more 2024-11-21 6.5 Medium
The Linux kernel through 5.8.13 does not properly enforce the Secure Boot Forbidden Signature Database (aka dbx) protection mechanism. This affects certs/blacklist.c and certs/system_keyring.c.
CVE-2020-26540 2 Apple, Foxitsoftware 3 Macos, Foxit Reader, Phantompdf 2024-11-21 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-2020-26290 1 Linuxfoundation 1 Dex 2024-11-21 9.3 Critical
Dex is a federated OpenID Connect provider written in Go. In Dex before version 2.27.0 there is a critical set of vulnerabilities which impacts users leveraging the SAML connector. The vulnerabilities enables potential signature bypass due to issues with XML encoding in the underlying Go library. The vulnerabilities have been addressed in version 2.27.0 by using the xml-roundtrip-validator from Mattermost (see related references).
CVE-2020-26244 1 Python Openid Connect Project 1 Python Openid Connect 2024-11-21 6.8 Medium
Python oic is a Python OpenID Connect implementation. In Python oic before version 1.2.1, there are several related cryptographic issues affecting client implementations that use the library. The issues are: 1) The IdToken signature algorithm was not checked automatically, but only if the expected algorithm was passed in as a kwarg. 2) JWA `none` algorithm was allowed in all flows. 3) oic.consumer.Consumer.parse_authz returns an unverified IdToken. The verification of the token was left to the discretion of the implementator. 4) iat claim was not checked for sanity (i.e. it could be in the future). These issues are patched in version 1.2.1.
CVE-2020-26122 1 Inspur 30 Nf5180m5, Nf5180m5 Firmware, Nf5260m5 and 27 more 2024-11-21 7.2 High
Inspur NF5266M5 through 3.21.2 and other server M5 devices allow remote code execution via administrator privileges. The Baseboard Management Controller (BMC) program of INSPUR server is weak in checking the firmware and lacks the signature verification mechanism, the attacker who obtains the administrator's rights can control the BMC by inserting malicious code into the firmware program and bypassing the current verification mechanism to upgrade the BMC.
CVE-2020-25490 1 Sqreen 1 Php Microagent 2024-11-21 7.3 High
Lack of cryptographic signature verification in the Sqreen PHP agent daemon before 1.16.0 makes it easier for remote attackers to inject rules for execution inside the virtual machine.
CVE-2020-25166 1 Bbraun 2 Datamodule Compactplus, Spacecom 2024-11-21 7.6 High
An improper verification of the cryptographic signature of firmware updates of the B. Braun Melsungen AG SpaceCom Version L81/U61 and earlier, and the Data module compactplus Versions A10 and A11 allows attackers to generate valid firmware updates with arbitrary content that can be used to tamper with devices.
CVE-2020-24439 3 Adobe, Apple, Microsoft 6 Acrobat, Acrobat Dc, Acrobat Reader and 3 more 2024-11-21 2.8 Low
Acrobat Reader DC for macOS versions 2020.012.20048 (and earlier), 2020.001.30005 (and earlier) and 2017.011.30175 (and earlier) are affected by a security feature bypass. While the practical security impact is minimal, a defense-in-depth fix has been implemented to further harden the Adobe Reader update process.
CVE-2020-24429 3 Adobe, Apple, Microsoft 6 Acrobat, Acrobat Dc, Acrobat Reader and 3 more 2024-11-21 7.7 High
Acrobat Reader DC versions 2020.012.20048 (and earlier), 2020.001.30005 (and earlier) and 2017.011.30175 (and earlier) for macOS are affected by a signature verification bypass that could result in local privilege escalation. Exploitation of this issue requires user interaction in that a victim must open a malicious file.
CVE-2020-23967 1 Drweb 1 Security Space 2024-11-21 7.8 High
Dr.Web Security Space versions 11 and 12 allow elevation of privilege for local users without administrative privileges to NT AUTHORITY\SYSTEM due to insufficient control during autoupdate.
CVE-2020-23533 1 Unionpayintl 1 Union Pay 2024-11-21 7.5 High
Union Pay up to 1.2.0, for web based versions contains a CWE-347: Improper Verification of Cryptographic Signature vulnerability, allows attackers to shop for free in merchants' websites and mobile apps, via a crafted authentication code (MAC) which is generated based on a secret key which is NULL.
CVE-2020-1026 1 Microsoft 1 Research Javascript Cryptography Library 2024-11-21 9.8 Critical
A Security Feature Bypass vulnerability exists in the MSR JavaScript Cryptography Library that is caused by multiple bugs in the library’s Elliptic Curve Cryptography (ECC) implementation.An attacker could potentially abuse these bugs to learn information about a server’s private ECC key (a key leakage attack) or craft an invalid ECDSA signature that nevertheless passes as valid.The security update addresses the vulnerability by fixing the bugs disclosed in the ECC implementation, aka 'MSR JavaScript Cryptography Library Security Feature Bypass Vulnerability'.
CVE-2020-16922 1 Microsoft 19 Windows 10, Windows 10 1507, Windows 10 1607 and 16 more 2024-11-21 5.3 Medium
<p>A spoofing vulnerability exists when Windows incorrectly validates file signatures. An attacker who successfully exploited this vulnerability could bypass security features and load improperly signed files.</p> <p>In an attack scenario, an attacker could bypass security features intended to prevent improperly signed files from being loaded.</p> <p>The update addresses the vulnerability by correcting how Windows validates file signatures.</p>
CVE-2020-16156 2 Fedoraproject, Perl 2 Fedora, Comprehensive Perl Archive Network 2024-11-21 7.8 High

This issue affects GRUB2 version 2.04 and prior versions.
CVE-2020-15302 1 Argent 1 Recoverymanager 2024-11-21 7.5 High
In Argent RecoveryManager before 0xdc350d09f71c48c5D22fBE2741e4d6A03970E192, the executeRecovery function does not require any signatures in the zero-guardian case, which allows attackers to cause a denial of service (locking) or a takeover.
CVE-2020-15240 1 Auth0 1 Omniauth-auth0 2024-11-21 7.4 High
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.
