CVE-2026-76156 Overview
CVE-2026-76156 is an operating system (OS) command injection vulnerability in the Datiphy Data Management Center API endpoint. The flaw affects versions v8.3.0 through v8.5.1. An authenticated administrator can execute arbitrary OS commands as root on the underlying host. The vulnerability is tracked as CWE-78, Improper Neutralization of Special Elements used in an OS Command.
Critical Impact
Successful exploitation grants attackers full root control of the Datiphy Data Management Center appliance, exposing monitored database traffic, audit records, and downstream infrastructure.
Affected Products
- Datiphy Data Management Center v8.3.0
- Datiphy Data Management Center versions between v8.3.0 and v8.5.1
- Datiphy Data Management Center v8.5.1

Technical Details for CVE-2026-76156
Vulnerability Analysis
The Datiphy Data Management Center exposes an API endpoint that passes user-supplied input into an operating system command without sufficient neutralization. Authenticated administrators can inject shell metacharacters that the underlying shell interprets during command construction. The API process runs with root privileges, so injected commands inherit unrestricted access to the host filesystem, network stack, and configuration stores. The vulnerability is classified under CWE-78 and requires no user interaction beyond an authenticated administrator session. The current EPSS score is 0.833% at the 55.027 percentile, reflecting moderate near-term exploitation probability.
Root Cause
The root cause is unsafe construction of OS command strings from API request parameters. The affected endpoint concatenates attacker-controlled values into a shell invocation rather than executing a fixed binary with an argument array. Because the process runs as root and no allow-list or shell-escaping routine validates the input, any metacharacter such as ;, |, or backticks pivots execution into arbitrary commands.
Attack Vector
Exploitation requires network reachability to the management API and valid administrator credentials. An attacker who has phished, brute-forced, or otherwise obtained admin credentials sends a crafted API request containing shell metacharacters in a vulnerable parameter. The Data Management Center evaluates the request server-side and executes the injected payload as root. Refer to the Zuso Security Advisory for technical specifics on the affected endpoint and parameters.
Detection Methods for CVE-2026-76156
Indicators of Compromise
- Unexpected child processes such as /bin/sh, bash, nc, curl, or wget spawned from the Datiphy API service.
- New outbound network connections from the Data Management Center host to unfamiliar IP addresses or reverse-shell listeners.
- Unauthorized modifications to /etc/passwd, /etc/shadow, SSH authorized_keys, or cron directories on the appliance.
- Administrator API requests containing shell metacharacters such as ;, &&, |, $( ), or backticks in body or query parameters.
Detection Strategies
- Inspect API access logs for administrator requests carrying shell metacharacters or encoded equivalents (%3B, %7C).
- Correlate authenticated administrator sessions with concurrent process-execution telemetry that shows shell descendants of the API service.
- Baseline the normal process tree of the Datiphy service and alert on any deviation, particularly root-owned child processes launching interpreters.
Monitoring Recommendations
- Forward API access logs, authentication events, and host process telemetry from the Data Management Center to a central analytics platform.
- Enable file integrity monitoring on system binaries, credential stores, and scheduled task directories on the appliance.
- Alert on any administrator API call that produces a non-zero exit shell invocation within the same request window.
How to Mitigate CVE-2026-76156
Immediate Actions Required
- Restrict network access to the Datiphy management API to a small allow-list of administrative jump hosts.
- Rotate all Datiphy administrator credentials and enforce multi-factor authentication on those accounts.
- Audit recent administrator API activity for shell metacharacters or anomalous command output.
- Contact Datiphy support to confirm a fixed version and plan an upgrade from any release in the v8.3.0–v8.5.1 range.
Patch Information
At publication, no vendor patch URL is listed in the NVD entry. Consult the Zuso Security Advisory and coordinate directly with Datiphy for a supported release beyond v8.5.1 that remediates the API command injection.
Workarounds
- Place the Data Management Center behind a reverse proxy or WAF that blocks shell metacharacters in API request bodies and query strings.
- Reduce the number of accounts holding the administrator role and review role assignments regularly.
- Segment the appliance into a management VLAN with no direct internet exposure until an upgrade is available.
# Example iptables restriction limiting API access to admin jump hosts
