CVE-2023-3763Public exploitNetwork attack vector

Sensitive-data disclosure via incomplete transport encryption

Published Jul 19, 2023 · Updated Aug 2, 2024

Cleartext transmission in InterGard do Brasil SGS 8.7.0 allows remote attackers to read sensitive data sent by the SQL Query Handler. The handler transmits sensitive data without fully encrypting the communication, but the public record does not identify the protocol, endpoint, or fields exposed. Exploitation requires unauthenticated network reachability and high attack complexity; the documented consequence is disclosure only.
