Vulnerabilities (CVE)

The SimpleSAMLphp SAML2 library is a PHP library for SAML2 related functionality. Prior to versions 4.17.0 and 5.0.0-alpha.20, there is a signature confusion attack in the HTTPRedirect binding. An attacker with any signed SAMLResponse via the HTTP-Redirect binding can cause the application to accept an unsigned message. Versions 4.17.0 and 5.0.0-alpha.20 contain a fix for the issue.

Versions of the package svix before 1.17.0 are vulnerable to Authentication Bypass due to an issue in the verify function where signatures of different lengths are incorrectly compared. An attacker can bypass signature verification by providing a shorter signature that matches the beginning of the actual signature. **Note:** The attacker would need to know a victim uses the Rust library for verification,no easy way to automatically check that; and uses webhooks by a service that uses Svix, and ... Versions of the package svix before 1.17.0 are vulnerable to Authentication Bypass due to an issue in the verify function where signatures of different lengths are incorrectly compared. An attacker can bypass signature verification by providing a shorter signature that matches the beginning of the actual signature. **Note:** The attacker would need to know a victim uses the Rust library for verification,no easy way to automatically check that; and uses webhooks by a service that uses Svix, and then figure out a way to craft a malicious payload that will actually include all of the correct identifiers needed to trick the receivers to cause actual issues.

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.

Insufficient verification of multiple header signatures while loading a Trusted Application (TA) may allow an attacker with privileges to gain code execution in that TA or the OS/kernel.

An issue in code signature validation was addressed with improved checks. This issue is fixed in macOS Big Sur 11.7, macOS Ventura 13, iOS 16, iOS 15.7 and iPadOS 15.7, macOS Monterey 12.6. An app may be able to bypass code signing checks.

Huawei APP HiWallet earlier than 5.0.3.100 versions do not support signature verification for APK file. An attacker could exploit this vulnerability to hijack the APK and upload modified APK file. Successful exploit could lead to the APP is hijacking.

The DynamicMetadataProvider class in saml/saml2/metadata/impl/DynamicMetadataProvider.cpp in OpenSAML-C in OpenSAML before 2.6.1 fails to properly configure itself with the MetadataFilter plugins and does not perform critical security checks such as signature verification, enforcement of validity periods, and other checks specific to deployments, aka CPPOST-105.

Signature Wrapping exists in OSCI-Transport 1.2 as used in OSCI Transport Library 1.6.1 (Java) and OSCI Transport Library 1.6 (.NET). An attacker with access to unencrypted OSCI protocol messages must send crafted protocol messages with duplicate IDs.

An issue was discovered in Enigmail before 1.9.9. In a variant of CVE-2017-17847, signature spoofing is possible for multipart/related messages because a signed message part can be referenced with a cid: URI but not actually displayed. In other words, the entire containing message appears to be signed, but the recipient does not see any of the signed text.

Improper verification of cryptographic signature vulnerability in Intel Security VirusScan Enterprise Linux (VSEL) 2.0.3 (and earlier) allows remote authenticated users to spoof update server and execute arbitrary code via a crafted input file.

An issue has been discovered on the Belden Hirschmann Tofino Xenon Security Appliance before 03.2.00. An incomplete firmware signature allows a local attacker to upgrade the equipment (kernel, file system) with unsigned, attacker-controlled, data. This occurs because the appliance_config file is signed but the .tar.sec file is unsigned.

Insufficient consistency checks in signature handling in the networking stack in Google Chrome prior to 58.0.3029.81 for Mac, Windows, and Linux, and 58.0.3029.83 for Android, allowed a remote attacker to incorrectly accept a badly formed X.509 certificate via a crafted HTML page.

Nimbus JOSE+JWT before 4.36 proceeds with ECKey construction without ensuring that the public x and y coordinates are on the specified curve, which allows attackers to conduct an Invalid Curve Attack in environments where the JCE provider lacks the applicable curve validation.

An issue was discovered in Enigmail before 1.9.9. Signature spoofing is possible because the UI does not properly distinguish between an attachment signature, and a signature that applies to the entire containing message, aka TBE-01-021. This is demonstrated by an e-mail message with an attachment that is a signed e-mail message in message/rfc822 format.

An issue was discovered in certain Apple products. iOS before 10.3 is affected. macOS before 10.12.4 is affected. The issue involves the "Security" component. It allows remote attackers to bypass intended access restrictions by leveraging a successful result from a SecKeyRawVerify API call with an empty signature.

shibsp/metadata/DynamicMetadataProvider.cpp in the Dynamic MetadataProvider plugin in Shibboleth Service Provider before 2.6.1 fails to properly configure itself with the MetadataFilter plugins and does not perform critical security checks such as signature verification, enforcement of validity periods, and other checks specific to deployments, aka SSPCPP-763.

The auto-update feature of Open Embedded Linux Entertainment Center (OpenELEC) 6.0.3, 7.0.1, and 8.0.4 uses neither encrypted connections nor signed updates. A man-in-the-middle attacker could manipulate the update packages to gain root access remotely.

Akeo Consulting Rufus prior to version 2.17.1187 does not adequately validate the integrity of updates downloaded over HTTP, allowing an attacker to easily convince a user to execute arbitrary code

FusionSphere OpenStack V100R006C00SPC102(NFV)has an improper verification of cryptographic signature vulnerability. The software does not verify the cryptographic signature. An attacker with high privilege may exploit this vulnerability to inject malicious software.

A PKCS#1 v1.5 signature verification routine in all Android releases from CAF using the Linux kernel may not check padding.

The tested version of Dominion Voting Systems ImageCast X does not validate application signatures to a trusted root certificate. Use of a trusted root certificate ensures software installed on a device is traceable to, or verifiable against, a cryptographic key provided by the manufacturer to detect tampering. An attacker could leverage this vulnerability to install malicious code, which could also be spread to other vulnerable ImageCast X devices via removable media.

An unprotected memory-access operation in optee_os in TrustedFirmware Open Portable Trusted Execution Environment (OP-TEE) before 3.20 allows a physically proximate adversary to bypass signature verification and install malicious trusted applications via electromagnetic fault injections.

The crypto.generateCRMFRequest method in Mozilla Firefox before 28.0 and SeaMonkey before 2.25 does not properly validate a certain key type, which allows remote attackers to cause a denial of service (application crash) via vectors that trigger generation of a key that supports the Elliptic Curve ec-dual-use algorithm.

XML Digital Signatures generated and validated using this package use SHA-1, which may allow an attacker to craft inputs which cause hash collisions depending on their control over the input.

MSI Center before 2.0.52.0 has Missing PE Signature Validation.

Google Chrome before 17.0.963.46 does not properly check signatures, which allows remote attackers to cause a denial of service (application crash) via unspecified vectors.

browserify-sign is a package to duplicate the functionality of node's crypto public key functions, much of this is based on Fedor Indutny's work on indutny/tls.js. An upper bound check issue in `dsaVerify` function allows an attacker to construct signatures that can be successfully verified by any public key, thus leading to a signature forgery attack.
