CVE-2021-44681: Veritas Enterprise Vault EVStgOfflineOpns Deserialization of Untrusted Data Remote Code Execution Vulnerability
An issue (5 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-14080).
Other sources
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Veritas Enterprise Vault. Authentication is not required to exploit this vulnerability. The specific flaw exists within EVStgOfflineOpns.exe. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of the Enterprise Vault Storage Service.
