CVE-2026-91757Hitachi Dynamic Link Manager for VMware OS command injection
CVE-2026-91757 is a OS command injection in Hitachi Dynamic Link Manager for VMware, rated high (7.1 on CVSS 3.1).
Why this priority: High severity, with no exploitation signal yet.
Published · Updated · NVD status: Deferred
What it is
Input reaches an operating-system command line, letting an attacker run their own commands on the host.
How it is reached
An attacker can exploit it from the same local network segment, without an account, but someone has to act first, such as opening a file or following a link. Success also depends on conditions the attacker does not fully control.
What an attacker gains
A successful attack can read the data it protects, change data or behaviour and take it offline. In practice, this kind of flaw lets an attacker run commands or code with the privileges of the affected service.
Is it being exploited?
There is no public report of exploitation yet.
What to do
- Upgrade Hitachi Dynamic Link Manager for VMware to 9.0.4-01 or later.
- Segment the networks that can reach it.
- Warn the people who use it, and filter files and links on the way in.
Description from NVD
OS Command Injection Vulnerability in Hitachi Dynamic Link Manager for VMware.
This issue affects Hitachi Dynamic Link Manager for VMware: from 7.3.0-00 before 9.0.4-01.
What this means for your architecture.
A CVE names a product. Whether it matters depends on where that product sits in your systems: what reaches it, which trust boundary it guards and what it can reach once compromised. Veriom maps your components, their relationships and your trust boundaries from your code, cloud and delivery evidence, so you can see where a component like this sits. The radar itself does not look at your systems.
Components it touches
- Application servers and the hosts they run on. The flaw sits between untrusted input and code or command execution.
- Template engines. The flaw sits between untrusted input and code or command execution.
Trust boundaries in play
- Local network segment. The attacker must share a network segment with the target.
- People who open files and links. Mail, chat and browsers are the delivery path.
- Between untrusted input and code or command execution. An attacker who crosses it can run commands or code with the privileges of the affected service.
Questions to answer about your own systems
- Where does Hitachi Dynamic Link Manager for VMware run in your systems, and at which version?
- Which network segments can reach them?
- What can it reach once compromised: which data stores, secrets and services?
