notation is a CLI tool to sign and verify OCI artifacts and container images. An attacker who has compromised a registry can cause users to verify the wrong artifact. The problem has been fixed in the release v1.0.0-rc.6. Users should upgrade their notation-go library to v1.0.0-rc.6 or above. Users unable to upgrade may restrict container registries to a set of secure and trusted container registries.Show less

In Moov signedxml through 1.0.0, parsing the raw XML (as received) can result in different output than parsing the canonicalized XML. Thus, signature validation can be bypassed via a Signature Wrapping attack (aka XSW).

Django-SES is a drop-in mail backend for Django. The django_ses library implements a mail backend for Django using AWS Simple Email Service. The library exports the `SESEventWebhookView class` intended to receive signed requests from AWS to handle email bounces, subscriptions, etc. These requests are signed by AWS and are verified by django_ses, however the verification of this signature was found to be flawed as it allowed users to specify arbitrary public certificates. This issue was patched in version 3.5.0.Show less

An issue was discovered in Veritas NetBackup IT Analytics 11 before 11.2.0. The application upgrade process included unsigned files that could be exploited and result in a customer installing unauthentic components. A malicious actor could install rogue Collector executable files (aptare.jar or upgrademanager.zip) on the Portal server, which might then be downloaded and installed on collectors.Show less

russh is a Rust SSH client and server library. Starting in version 0.34.0 and prior to versions 0.36.2 and 0.37.1, Diffie-Hellman key validation is insufficient, which can lead to insecure shared secrets and therefore breaks confidentiality. Connections between a russh client and server or those of a russh peer with some other misbehaving peer are most likely to be problematic. These may vulnerable to eavesdropping. Most other implementations reject such keys, so this is mainly an interoperability issue in such a case. This issue is fixed in versions 0.36.2 and 0.37.1Show less

A vulnerability in the upgrade signature verification of Cisco Enterprise NFV Infrastructure Software (NFVIS) could allow an unauthenticated, local attacker to provide an unauthentic upgrade file for upload. This vulnerability is due to insufficient cryptographic signature verification of upgrade files. An attacker could exploit this vulnerability by providing an administrator with an unauthentic upgrade file. A successful exploit could allow the attacker to fully compromise the Cisco NFVIS system.Show less

In ConnectWise Control through 22.9.10032 (formerly known as ScreenConnect), after an executable file is signed, additional instructions can be added without invalidating the signature, such as instructions that result in offering the end user a (different) attacker-controlled executable file. It is plausible that the end user may allow the download and execution of this file to proceed. There are ConnectWise Control configuration options that add mitigations.Show less

OpenZeppelin Contracts for Cairo is a library for secure smart contract development written in Cairo for StarkNet, a decentralized ZK Rollup. `is_valid_eth_signature` is missing a call to `finalize_keccak` after calling `verify_eth_signature`. As a result, any contract using `is_valid_eth_signature` from the account library (such as the `EthAccount` preset) is vulnerable to a malicious sequencer. Specifically, the malicious sequencer would be able to bypass signature validation to impersonate an instance of these accounts. The issue has been patched in 0.6.1. Show less

reason-jose is a JOSE implementation in ReasonML and OCaml.`Jose.Jws.validate` does not check HS256 signatures. This allows tampering of JWS header and payload data if the service does not perform additional checks. Such tampering could expose applications using reason-jose to authorization bypass. Applications relying on JWS claims assertion to enforce security boundaries may be vulnerable to privilege escalation. This issue has been patched in version 0.8.2.Show less
