CVE-2020-7224Network attack vector

Code execution via altered OpenSSL parameters

Published Apr 16, 2020 · Updated Aug 4, 2024

Library-loading validation in Aviatrix OpenVPN client 2.5.7 and earlier allows attackers to execute code through altered OpenSSL parameters. The client accepts OpenSSL parameters that differ from the issued value set and uses them to load an unauthorized third-party library. Exploitation requires control of those parameters; the vendor has not disclosed the exact parameter names, delivery path, or resulting process privileges.
