Union Pay up to 3.3.12, for iOS mobile apps, contains a CWE-347: Improper Verification of Cryptographic Signature vulnerability, allows attackers to shop for free in merchants' websites and mobile apps, via a crafted authentication code (MAC) which is generated based on a secret key which is NULL.
CVE-2021-32738 1 Stellar 1 Js-stellar-sdk 2024-02-04 4.0 MEDIUM 6.5 MEDIUM
js-stellar-sdk is a Javascript library for communicating with a Stellar Horizon server. The `Utils.readChallengeTx` function used in SEP-10 Stellar Web Authentication states in its function documentation that it reads and validates the challenge transaction including verifying that the `serverAccountID` has signed the transaction. In js-stellar-sdk before version 8.2.3, the function does not verify that the server has signed the transaction. Applications that also used `Utils.verifyChallengeTxThreshold` or `Utils.verifyChallengeTxSigners` to verify the signatures including the server signature on the challenge transaction are unaffected as those functions verify the server signed the transaction. Applications calling `Utils.readChallengeTx` should update to version 8.2.3, the first version with a patch for this vulnerability, to ensure that the challenge transaction is completely valid and signed by the server creating the challenge transaction.
CVE-2021-24020 1 Fortinet 1 Fortimail 2024-02-04 7.5 HIGH 9.8 CRITICAL
A missing cryptographic step in the implementation of the hash digest algorithm in FortiMail 6.4.0 through 6.4.4, and 6.2.0 through 6.2.7 may allow an unauthenticated attacker to tamper with signed URLs by appending further data which allows bypass of signature verification.
CVE-2021-21405 1 Filecoin 1 Lotus 2024-02-04 5.0 MEDIUM 7.5 HIGH
Lotus is an Implementation of the Filecoin protocol written in Go. BLS signature validation in lotus uses blst library method VerifyCompressed. This method accepts signatures in 2 forms: "serialized", and "compressed", meaning that BLS signatures can be provided as either of 2 unique byte arrays. Lotus block validation functions perform a uniqueness check on provided blocks. Two blocks are considered distinct if the CIDs of their blockheader do not match. The CID method for blockheader includes the BlockSig of the block. The result of these issues is that it would be possible to punish miners for valid blocks, as there are two different valid block CIDs available for each block, even though this must be unique. By switching from the go based `blst` bindings over to the bindings in `filecoin-ffi`, the code paths now ensure that all signatures are compressed by size and the way they are deserialized. This happened in https://github.com/filecoin-project/lotus/pull/5393.
CVE-2021-22735 1 Schneider-electric 4 Homelynk, Homelynk Firmware, Spacelynk and 1 more 2024-02-04 6.5 MEDIUM 7.2 HIGH
Improper Verification of Cryptographic Signature vulnerability exists inhomeLYnk (Wiser For KNX) and spaceLYnk V2.60 and prior which could allow remote code execution when unauthorized code is copied to the device.
CVE-2021-29451 1 Manydesigns 1 Portofino 2024-02-04 6.4 MEDIUM 9.1 CRITICAL
Portofino is an open source web development framework. Portofino before version 5.2.1 did not properly verify the signature of JSON Web Tokens. This allows forging a valid JWT. The issue will be patched in the upcoming 5.2.1 release.
CVE-2021-3421 3 Fedoraproject, Redhat, Rpm 3 Fedora, Enterprise Linux, Rpm 2024-02-04 4.3 MEDIUM 5.5 MEDIUM
A flaw was found in the RPM package in the read functionality. This flaw allows an attacker who can convince a victim to install a seemingly verifiable package or compromise an RPM repository, to cause RPM database corruption. The highest threat from this vulnerability is to data integrity. This flaw affects RPM versions before 4.17.0-alpha.
CVE-2021-32685 1 Togatech 1 Tenvoy 2024-02-04 7.5 HIGH 9.8 CRITICAL
tEnvoy contains the PGP, NaCl, and PBKDF2 in node.js and the browser (hashing, random, encryption, decryption, signatures, conversions), used by TogaTech.org. In versions prior to 7.0.3, the `verifyWithMessage` method of `tEnvoyNaClSigningKey` always returns `true` for any signature that has a SHA-512 hash matching the SHA-512 hash of the message even if the signature was invalid. This issue is patched in version 7.0.3. As a workaround: In `tenvoy.js` under the `verifyWithMessage` method definition within the `tEnvoyNaClSigningKey` class, ensure that the return statement call to `this.verify` ends in `.verified`.
CVE-2021-20487 1 Ibm 18 8335-gth, 8335-gtx, 9008-22l and 15 more 2024-02-04 6.5 MEDIUM 9.1 CRITICAL
IBM Power9 Self Boot Engine(SBE) could allow a privileged user to inject malicious code and compromise the integrity of the host firmware bypassing the host firmware signature verification process.
CVE-2021-3196 1 Hitachi 1 Id Bravura Security Fabric 2024-02-04 6.5 MEDIUM 8.8 HIGH
An issue was discovered in Hitachi ID Bravura Security Fabric 11.0.0 through 11.1.3, 12.0.0 through 12.0.2, and 12.1.0. When using federated identity management (authenticating via SAML through a third-party identity provider), an attacker can inject additional data into a signed SAML response being transmitted to the service provider (ID Bravura Security Fabric). The application successfully validates the signed values but uses the unsigned malicious values. An attacker with lower-privilege access to the application can inject the username of a high-privilege user to impersonate that user.
CVE-2021-3445 3 Fedoraproject, Redhat, Rpm 3 Fedora, Enterprise Linux, Libdnf 2024-02-04 5.1 MEDIUM 7.5 HIGH
A flaw was found in libdnf's signature verification functionality in versions before 0.60.1. This flaw allows an attacker to achieve code execution if they can alter the header information of an RPM package and then trick a user or system into installing it. The highest risk of this vulnerability is to confidentiality, integrity, as well as system availability.
CVE-2021-23992 1 Mozilla 1 Thunderbird 2024-02-04 4.3 MEDIUM 4.3 MEDIUM
Thunderbird did not check if the user ID associated with an OpenPGP key has a valid self signature. An attacker may create a crafted version of an OpenPGP key, by either replacing the original user ID, or by adding another user ID. If Thunderbird imports and accepts the crafted key, the Thunderbird user may falsely conclude that the false user ID belongs to the correspondent. This vulnerability affects Thunderbird < 78.9.1.
CVE-2021-34433 1 Eclipse 1 Californium 2024-02-04 5.0 MEDIUM 7.5 HIGH
In Eclipse Californium version 2.0.0 to 2.6.4 and 3.0.0-M1 to 3.0.0-M3, the certificate based (x509 and RPK) DTLS handshakes accidentally succeeds without verifying the server side's signature on the client side, if that signature is not included in the server's ServerKeyExchange.
