Vulnerability Data

A Command Injection issue was discovered in ContentStore/Base/CVDataPipe.dll in Commvault before v11 SP6. A certain message parsing function inside the Commvault service does not properly validate the input of an incoming string before passing it to CreateProcess. As a result,…

more

a specially crafted message can inject commands that will be executed on the target operating system. Exploitation of this vulnerability does not require authentication and can lead to SYSTEM level privilege on any system running the cvd daemon. This is a different vulnerability than CVE-2017-3195.

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

SC-27 Platform-independent Applications
addresses: CWE-78

Platform-independent apps typically execute inside a managed runtime or sandbox that restricts direct OS command execution, reducing the ability to exploit OS command injection.

SI-10 Information Input Validation
addresses: CWE-78

Validates inputs to block special elements that would alter OS command execution.

PR.PS-06 mostly match
prevents

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.

PR.PS-02 partial match
prevents

Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
