AiSOC Command Injection via CrowdStrike Real Time Response

CVE advisorySeverity: CRITICAL (CVSS 9.4)

CVE-2026-103056

The vulnerability exists within an internal 'actions service' used for managing endpoint command strings. While the software may be network-accessible, this specific functionality typically operates as an internal backend service rather than a public-facing edge service, meaning public internet exposure is uncommon in standard deployments.

Horizon Alert

Summary of the vulnerability and why it matters

A command injection vulnerability has been identified in the AiSOC actions service, specifically affecting how it builds CrowdStrike Real Time Response command strings. This flaw could allow authenticated users to execute arbitrary commands on managed endpoints with elevated privileges. The main concern is confirming relevance and exposure.

Attack Path

How an attacker could exploit the issue

An attacker with authenticated access could exploit this vulnerability by providing specially crafted input that manipulates command strings used to interact with CrowdStrike's Real Time Response. This could allow them to execute arbitrary commands on managed endpoints, potentially leading to a compromise of the endpoint's operating system.

Entry condition: Authenticated user access.
Trigger point: Injecting single quotes into parameters.
Resulting risk: Arbitrary command execution on endpoints.

Live Threat

Current exploitation, exposure, and threat context

When supported by the advisory, authenticated users could execute arbitrary commands on managed endpoints with SYSTEM or root privileges by injecting unescaped parameters into the actions service. This could affect system integrity and allow unauthorized command execution.

Operational Fix

Recommended remediation, mitigation, and detection steps

This vulnerability in AiSOC's actions service affects authenticated users, potentially allowing arbitrary command execution on managed endpoints. The primary responsibility likely falls to the platform or security operations team managing AiSOC, with immediate triage focused on confirming the presence of the vulnerable component and assessing its exposure and criticality within the environment.

Frequently asked questions

What is AiSOC and how is it used?

AiSOC is a software platform designed to manage and orchestrate security operations. It includes specialized modules, such as an actions service, which allows administrators to interact with managed endpoints. Teams use this tool to automate responses, including executing tasks via integrated services like CrowdStrike Real Time Response, which helps security professionals investigate and remediate threats across their infrastructure.

What does CVE-2026-103056 mean for my security?

This CVE describes a command injection vulnerability, classified under CWE-78. It occurs when software improperly processes input, allowing an attacker to inject and execute their own system commands. In this specific case, the flaw exists because the AiSOC actions service fails to properly sanitize input parameters before passing them to the CrowdStrike Real Time Response component, potentially granting unauthorized system-level control.

How can an attacker trigger this vulnerability?

An attacker must have authenticated access to the AiSOC environment to trigger this bug. The issue is specifically initiated by injecting single quotes into parameters like file_path, path, or script_args. If a user simply uses the software for standard, authorized tasks without supplying these specially crafted character sequences, they will not trigger the vulnerability.

Is my AiSOC instance at risk from the internet?

Halo Surface Signal indicates that while the AiSOC platform might be network-accessible, the vulnerable actions service typically functions as an internal backend component. This means the specific path used to trigger this vulnerability is unlikely to be exposed directly to the public internet in standard deployments, lowering the likelihood of remote exploitation by external actors.

What should I do if I manage AiSOC?

First, verify whether you have AiSOC installed and identify if your version falls within the affected range of 7.2.0 prior to 12.0.0. Once you confirm the software is in use, prioritize reviewing your deployment configuration to assess the level of exposure. Coordinate with your platform or security operations teams to plan for necessary version updates provided by the vendor to resolve the command injection flaw.
