Title
Cisco Expressway Series and TelePresence Video Communication Server Image Verification Vulnerability
Summary
A vulnerability in the image verification function of Cisco Expressway Series and Cisco TelePresence Video Communication Server (VCS) could allow an authenticated, remote attacker to execute code with internal user privileges on the underlying operating system. The vulnerability is due to insufficient validation of the content of upgrade packages. An attacker could exploit this vulnerability by uploading a malicious archive to the Upgrade page of the administrative web interface. A successful exploit could allow the attacker to execute code with user-level privileges (the _nobody account) on the underlying operating system.

Title
Improper Verification of Cryptographic Signature in tenvoy
Summary
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`.

Title
Improper privilege management in repair process of MA for Windows
Summary
Improper access control vulnerability in the repair process for McAfee Agent for Windows prior to 5.7.4 could allow a local attacker to perform a DLL preloading attack using unsigned DLLs. This would result in elevation of privileges and the ability to execute arbitrary code as the system user, through not correctly protecting a temporary directory used in the repair process and not checking the DLL signature.

Title
Missing validation of JWT signature in `grassrootza/grassroot-platform`
Summary
Grassroot Platform is an application to make it faster, cheaper and easier to persistently organize and mobilize people in low-income communities. Grassroot Platform before master deployment as of 2021-04-16 did not properly verify the signature of JSON Web Tokens when refreshing an existing JWT. This allows to forge a valid JWT. The problem has been patched in version 1.3.1 by deprecating the JWT refresh function, which was an overdue deprecation regardless (the "refresh" flow is no longer used).

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.
