CVE-2019-1736 1 Cisco 22 Fmc1000-k9 Bios, Fmc1000-k9 Firmware, Fmc2500-k9 Bios and 19 more 2020-10-23 6.9 MEDIUM 6.6 MEDIUM
A vulnerability in the firmware of the Cisco UCS C-Series Rack Servers could allow an authenticated, physical attacker to bypass Unified Extensible Firmware Interface (UEFI) Secure Boot validation checks and load a compromised software image on an affected device. The vulnerability is due to improper validation of the server firmware upgrade images. An attacker could exploit this vulnerability by installing a server firmware version that would allow the attacker to disable UEFI Secure Boot. A successful exploit could allow the attacker to bypass the signature validation checks that are done by UEFI Secure Boot technology and load a compromised software image on the affected device. A compromised software image is any software image that has not been digitally signed by Cisco.
CVE-2016-1000338 1 Bouncycastle 1 Legion-of-the-bouncy-castle-java-crytography-api 2020-10-20 5.0 MEDIUM 7.5 HIGH
In Bouncy Castle JCE Provider version 1.55 and earlier the DSA does not fully validate ASN.1 encoding of signature on verification. It is possible to inject extra elements in the sequence making up the signature and still have it validate, which in some cases may allow the introduction of 'invisible' data into a signed structure.
CVE-2016-1000342 2 Bouncycastle, Debian 2 Legion-of-the-bouncy-castle-java-crytography-api, Debian Linux 2020-10-20 5.0 MEDIUM 7.5 HIGH
In the Bouncy Castle JCE Provider version 1.55 and earlier ECDSA does not fully validate ASN.1 encoding of signature on verification. It is possible to inject extra elements in the sequence making up the signature and still have it validate, which in some cases may allow the introduction of 'invisible' data into a signed structure.
CVE-2020-16922 1 Microsoft 8 Windows 10, Windows 7, Windows 8.1 and 5 more 2020-10-20 2.1 LOW 5.5 MEDIUM
A spoofing vulnerability exists when Windows incorrectly validates file signatures, aka 'Windows Spoofing Vulnerability'.
CVE-2019-15796 3 Canonical, Debian, Ubuntu 3 Ubuntu Linux, Python-apt, Python-apt 2020-10-19 2.6 LOW 4.7 MEDIUM
Python-apt doesn't check if hashes are signed in `Version.fetch_binary()` and `Version.fetch_source()` of apt/package.py or in `_fetch_archives()` of apt/cache.py in version 1.9.3ubuntu2 and earlier. This allows downloads from unsigned repositories which shouldn't be allowed and has been fixed in verisions 1.9.5, 1.9.0ubuntu1.2, 1.6.5ubuntu0.1, 1.1.0~beta1ubuntu0.16.04.7, 0.9.3.5ubuntu3+esm2, and 0.8.3ubuntu7.5.
CVE-2019-1729 1 Cisco 20 Nexus 3000, Nexus 3100, Nexus 3100-z and 17 more 2020-10-09 6.6 MEDIUM 6.0 MEDIUM
A vulnerability in the CLI implementation of a specific command used for image maintenance for Cisco NX-OS Software could allow an authenticated, local attacker to overwrite any file on the file system including system files. These file overwrites by the attacker are accomplished at the root privilege level. The vulnerability occurs because there is no verification of user-input parameters and or digital-signature verification for image files when using a specific CLI command. An attacker could exploit this vulnerability by authenticating to the device and issuing a command at the CLI. Because an exploit could allow the attacker to overwrite any file on the disk, including system files, a denial of service (DoS) condition could occur. The attacker must have valid administrator credentials for the affected device to exploit this vulnerability.
CVE-2018-7340 1 Cisco 1 Duo Network Gateway 2020-10-02 5.0 MEDIUM 7.5 HIGH
Duo Network Gateway 1.2.9 and earlier may incorrectly utilize the results of XML DOM traversal and canonicalization APIs in such a way that an attacker may be able to manipulate the SAML data without invalidating the cryptographic signature, allowing the attack to potentially bypass authentication to SAML service providers.
CVE-2019-10201 1 Redhat 2 Keycloak, Single Sign-on 2020-10-02 5.5 MEDIUM 8.1 HIGH
It was found that Keycloak's SAML broker, versions up to 6.0.1, did not verify missing message signatures. If an attacker modifies the SAML Response and removes the <Signature> sections, the message is still accepted, and the message can be modified. An attacker could use this flaw to impersonate other users and gain access to sensitive information.
CVE-2020-25490 1 Sqreen 1 Php Microagent 2020-09-25 7.5 HIGH 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-2020-14515 1 Wibu 1 Codemeter 2020-09-22 5.0 MEDIUM 7.5 HIGH
CodeMeter (All versions prior to 6.90 when using CmActLicense update files with CmActLicense Firm Code) has an issue in the license-file signature checking mechanism, which allows attackers to build arbitrary license files, including forging a valid license file as if it were a valid license file of an existing vendor. Only CmActLicense update files with CmActLicense Firm Code are affected.
CVE-2018-0114 1 Cisco 1 Node-jose 2020-09-04 5.0 MEDIUM 7.5 HIGH
A vulnerability in the Cisco node-jose open source library before 0.11.0 could allow an unauthenticated, remote attacker to re-sign tokens using a key that is embedded within the token. The vulnerability is due to node-jose following the JSON Web Signature (JWS) standard for JSON Web Tokens (JWTs). This standard specifies that a JSON Web Key (JWK) representing a public key can be embedded within the header of a JWS. This public key is then trusted for verification. An attacker could exploit this by forging valid JWS objects by removing the original signature, adding a new public key to the header, and then signing the object using the (attacker-owned) private key associated with the public key embedded in that JWS header.
CVE-2019-6318 1 Hp 286 Color Laserjet Cm4540 Mfp, Color Laserjet Cm4540 Mfp Firmware, Color Laserjet Enterprise Cp5525 and 283 more 2020-08-24 7.5 HIGH 9.8 CRITICAL
