Improper Verification of Cryptographic Signature

A vulnerability in software image verification in Cisco IOS XE Software could allow an unauthenticated, physical attacker to install and boot a malicious software image or execute unsigned binaries on an affected device. The vulnerability is due to an improper check on the area of code that manages the verification of the digital signatures of system image files during the initial boot process. An attacker could exploit this vulnerability by loading unsigned software on an affected device. A successful exploit could allow the attacker to install and boot a malicious software image or execute unsigned binaries on the targeted device.Show less

An issue was discovered in fastecdsa before 2.1.2. When using the NIST P-256 curve in the ECDSA implementation, the point at infinity is mishandled. This means that for an extreme value in k and s^-1, the signature verification fails even if the signature is correct. This behavior is not solely a usability problem. There are some threat models where an attacker can benefit by successfully guessing users for whom signature verification will fail.Show less

An issue was discovered in Aviatrix Controller through 5.1. An attacker with any signed SAML assertion from the Identity Provider can establish a connection (even if that SAML assertion has expired or is from a user who is not authorized to access Aviatrix), aka XML Signature Wrapping.Show less

An issue has been found in PowerDNS Recursor 4.1.0 through 4.3.0 where records in the answer section of a NXDOMAIN response lacking an SOA were not properly validated in SyncRes::processAnswer, allowing an attacker to bypass DNSSEC validation.Show less

Opto 22 SoftPAC Project Version 9.6 and prior. Paths specified within the zip files used to update the SoftPAC firmware are not sanitized. As a result, an attacker with user privileges can gain arbitrary file write access with system access.Show less

Spring Security versions 5.2.x prior to 5.2.4 and 5.3.x prior to 5.3.2 contain a signature wrapping vulnerability during SAML response validation. When using the spring-security-saml2-service-provider component, a malicious user can carefully modify an otherwise valid SAML response and append an arbitrary assertion that Spring Security will accept as valid.Show less

An issue was discovered in OpenStack Keystone before 15.0.1, and 16.0.0. The EC2 API doesn't have a signature TTL check for AWS Signature V4. An attacker can sniff the Authorization header, and then use it to reissue an OpenStack token an unlimited number of times.Show less

A vulnerability in the Image Signature Verification feature of Cisco Firepower Threat Defense (FTD) Software could allow an authenticated, remote attacker with administrator-level credentials to install a malicious software patch on an affected device. The vulnerability is due to improper verification of digital signatures for patch images. An attacker could exploit this vulnerability by crafting an unsigned software patch to bypass signature checks and loading it on an affected device. A successful exploit could allow the attacker to boot a malicious software patch image.Show less

An issue was discovered on Tata Sonata Smart SF Rush 1.12 devices. It has been identified that the smart band has no pairing (mode 0 Bluetooth LE security level) The data being transmitted over the air is not encrypted. Adding to this, the data being sent to the smart band doesn't have any authentication or signature verification. Thus, any attacker can control a parameter of the device.Show less

Wlan binary which is not signed with OEMs RoT is working on secure device without authentication failure in Snapdragon Compute, Snapdragon Consumer IOT, Snapdragon Industrial IOT, Snapdragon Mobile in SDA845, SDM845, SDM850Show less

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'.Show less

An issue was discovered on Samsung mobile devices with L(5.0/5.1) and M(6.0) (with Fingerprint support) software. The check of an application's signature can be bypassed during installation. The Samsung ID is SVE-2016-5923 (June 2016).Show less

The "Apache NetBeans" autoupdate system does not fully validate code signatures. An attacker could modify the downloaded nbm and include additional code. "Apache NetBeans" versions up to and including 11.2 are affected by this vulnerability.Show less

MITRE is populating this ID because it was assigned prior to Lenovo becoming a CNA. A vulnerability was reported (fixed and publicly disclosed in 2015) in Lenovo System Update version 5.07.0008 and prior that could allow the signature check of an update to be bypassed.Show less

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.Show less
