CVE-2020-27688

23
FAUCET Score

CVE-2020-27688 describes a critical vulnerability in RVTools 4.0.6, where the RVToolsPasswordEncryption.exe utility uses a static IV and key for password encryption, making stored vSphere credentials easily decryptable. This flaw presents a high-severity risk (CVSS 7.5), allowing unauthenticated remote attackers to compromise sensitive vSphere accounts due to the predictable encryption. While no active exploitation, public exploit code, or significant community discussion has been observed, the inherent ease of decryption poses a substantial security concern for affected systems.
