CVE-2019-18780
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAn arbitrary command injection vulnerability in the Cluster Server component of Veritas InfoScale allows an unauthenticated remote attacker to execute arbitrary commands as root or administrator. These Veritas products are affected: Access 7.4.2 and earlier, Access Appliance 7.4.2 and earlier, Flex Appliance 1.2 and earlier, InfoScale 7.3.1 and earlier, InfoScale between 7.4.0 and 7.4.1, Veritas Cluster Server (VCS) 6.2.1 and earlier on Linux/UNIX, Veritas Cluster Server (VCS) 6.1 and earlier on Windows, Storage Foundation HA (SFHA) 6.2.1 and earlier on Linux/UNIX, and Storage Foundation HA (SFHA) 6.1 and earlier on Windows.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysisUser input reaches a command interpreter without being fully separated from the command itself, so an attacker can append instructions of their own. Because those run with the application's privileges, it frequently means control of the host. The lasting fix is to avoid constructing commands from input — call APIs directly and pass arguments as data, never as concatenated strings.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade to versions greater than those affected: Access/Access Appliance > 7.4.2, Flex Appliance > 1.2, InfoScale > 7.4.1, Cluster Server > 6.2.1 (Linux/UNIX) or > 6.1 (Windows), Storage Foundation HA > 6.2.1 (Linux/UNIX) or > 6.1 (Windows) - contact Veritas for exact fixed release numbers
- 1. Identify the specific Veritas product and version currently installed from the list: Access <= 7.4.2, Access Appliance <= 7.4.2, Flex Appliance <= 1.2, InfoScale <= 7.3.1 or 7.4.0-7.4.1, Cluster Server <= 6.1 (Windows) or <= 6.2.1 (Linux/UNIX), Storage Foundation HA <= 6.1 (Windows) or <= 6.2.1 (Linux/UNIX)
- 2. Contact Veritas customer support or access the Veritas support portal to obtain the specific patched version for your product
- 3. Review the vendor security advisory VTS19-003 at https://www.veritas.com/content/support/en_US/security/VTS19-003 for detailed patch information
- 4. Schedule a maintenance window - this is a critical remote code execution vulnerability
- 5. Before upgrading, back up all configuration data and verify backup integrity
- 6. Apply the vendor-provided patch or upgrade to the fixed version as specified in VTS19-003
- 7. After upgrade, verify the Cluster Server component is functioning correctly
- 8. Confirm the vulnerability is remediated by reviewing system logs and running integrity checks
