Title
Flawed SK_LOAD module authenticity check in Texas Instruments OMAP L138
Summary
The Texas Instruments OMAP L138 (secure variants) trusted execution environment (TEE) performs an RSA check implemented in mask ROM when loading a module through the SK_LOAD routine. However, only the module header authenticity is validated. An adversary can re-use any correctly signed header and append a forged payload, to be encrypted using the CEK (obtainable through CVE-2022-25332) in order to obtain arbitrary code execution in secure context. This constitutes a full break of the TEE security architecture.

Title
Trivial signature forgery in ecdsautils
Summary
ecdsautils is a tiny collection of programs used for ECDSA (keygen, sign, verify). `ecdsa_verify_[prepare_]legacy()` does not check whether the signature values `r` and `s` are non-zero. A signature consisting only of zeroes is always considered valid, making it trivial to forge signatures. Requiring multiple signatures from different public keys does not mitigate the issue: `ecdsa_verify_list_legacy()` will accept an arbitrary number of such forged signatures. Both the `ecdsautil verify` CLI command and the libecdsautil library are affected. The issue has been fixed in ecdsautils 0.4.1. All older versions of ecdsautils (including versions before the split into a library and a CLI utility) are vulnerable.

Title
Improper Verification of Cryptographic Signature in `node-forge`
Summary
Forge (also called `node-forge`) is a native implementation of Transport Layer Security in JavaScript. Prior to version 1.3.0, RSA PKCS#1 v1.5 signature verification code does not properly check `DigestInfo` for a proper ASN.1 structure. This can lead to successful verification with signatures that contain invalid structures but a valid digest. The issue has been addressed in `node-forge` version 1.3.0. There are currently no known workarounds.

Title
Improper Verification of Cryptographic Signature in `node-forge`
Summary
Forge (also called `node-forge`) is a native implementation of Transport Layer Security in JavaScript. Prior to version 1.3.0, RSA PKCS#1 v1.5 signature verification code does not check for tailing garbage bytes after decoding a `DigestInfo` ASN.1 structure. This can allow padding bytes to be removed and garbage data added to forge a signature when a low public exponent is being used. The issue has been addressed in `node-forge` version 1.3.0. There are currently no known workarounds.

Title
Improper Verification of Cryptographic Signature in node-forge
Summary
Forge (also called `node-forge`) is a native implementation of Transport Layer Security in JavaScript. Prior to version 1.3.0, RSA PKCS#1 v1.5 signature verification code is lenient in checking the digest algorithm structure. This can allow a crafted structure that steals padding bytes and uses unchecked portion of the PKCS#1 encoded message to forge a signature when a low public exponent is being used. The issue has been addressed in `node-forge` version 1.3.0. There are currently no known workarounds.

Title
Failure to validate signature during handshake in @chainsafe/libp2p-noise
Summary
`@chainsafe/libp2p-noise` contains TypeScript implementation of noise protocol, an encryption protocol used in libp2p. `@chainsafe/libp2p-noise` before 4.1.2 and 5.0.3 does not correctly validate signatures during the handshake process. This may allow a man-in-the-middle to pose as other peers and get those peers banned. Users should upgrade to version 4.1.2 or 5.0.3 to receive a patch. There are currently no known workarounds.

Summary
Octobercms is a self-hosted CMS platform based on the Laravel PHP Framework. Affected versions of OctoberCMS did not validate gateway server signatures. As a result non-authoritative gateway servers may be used to exfiltrate user private keys. Users are advised to upgrade their installations to build 474 or v1.1.10. The only known workaround is to manually apply the patch (e3b455ad587282f0fbcb7763c6d9c3d000ca1e6a) which adds server signature validation.

Title
Improper Verification of Cryptographic Signature in wire-server
Summary
wire-server provides back end services for Wire, an open source messenger. In versions of wire-server prior to the 2022-01-27 release, it was possible to craft DSA Signatures to bypass SAML SSO and impersonate any Wire user with SAML credentials. In teams with SAML, but without SCIM, it was possible to create new accounts with fake SAML credentials. Under certain conditions that can be established by an attacker, an upstream library for parsing, rendering, signing, and validating SAML XML data was accepting public keys as trusted that were provided by the attacker in the signature. As a consequence, the attacker could login as any user in any Wire team with SAML SSO enabled. If SCIM was not enabled, the attacker could also create new users with new SAML NameIDs. In order to exploit this vulnerability, the attacker needs to know the SSO login code (distributed to all team members with SAML credentials and visible in the Team Management app), the SAML EntityID identifying the IdP (a URL not considered sensitive, but usually hard to guess, also visible in Team Management), and the SAML NameID of the user (usually an email address or a nick). The issue has been fixed in wire-server `2022-01-27` and is already deployed on all Wire managed services. On premise instances of wire-server need to be updated to `2022-01-27`, so that their backends are no longer affected. There are currently no known workarounds. More detailed information about how to reproduce the vulnerability and mitigation strategies is available in the GitHub Security Advisory.

CAPEC-463: Padding Oracle Crypto Attack
An adversary is able to efficiently decrypt data without knowing the decryption key if a target system leaks data on whether or not a padding error happened while decrypting the ciphertext. A target system that leaks this type of information becomes the padding oracle and an adversary is able to make use of that oracle to efficiently decrypt data without knowing the decryption key by issuing on average 128*b calls to the padding oracle (where b is the number of bytes in the ciphertext block). In addition to performing decryption, an adversary is also able to produce valid ciphertexts (i.e., perform encryption) by using the padding oracle, all without knowing the encryption key.
CAPEC-475: Signature Spoofing by Improper Validation
An adversary exploits a cryptographic weakness in the signature verification algorithm implementation to generate a valid signature without knowing the key.
