CVE-2021-44677: Veritas Enterprise Vault EVExchangeWebServicesProxy Deserialization of Untrusted Data Remote Code Execution Vulnerability
First published: Mon Dec 06 2021(Updated: )
An issue (1 of 6) was discovered in Veritas Enterprise Vault through 14.1.2. On start-up, the Enterprise Vault application starts several services that listen on random .NET Remoting TCP ports for possible commands from client applications. These TCP services can be exploited due to deserialization behavior that is inherent to the .NET Remoting service. A malicious attacker can exploit both TCP remoting services and local IPC services on the Enterprise Vault Server. This vulnerability is mitigated by properly configuring the servers and firewall as described in the vendor's security alert for this vulnerability (VTS21-003, ZDI-CAN-14078).
