CVE-2026-103056 in AiSOC
Summary
by MITRE • 09/30/2026
AiSOC versions 7.2.0 before 12.0.0 contain a command injection vulnerability in the actions service that builds CrowdStrike Real Time Response command strings by interpolating unescaped action parameters in crowdstrike_rtr.py and endpoint.py. Authenticated users can inject single quotes into file_path, path, script_name, or script_args parameters to break out of quoted arguments and execute arbitrary commands on managed endpoints with SYSTEM or root privileges.

AiSOC versions prior to 12.0.0 contain a critical command injection vulnerability within the actions service component responsible for managing CrowdStrike Real Time Response operations. This flaw arises from improper neutralization of special elements used in operating system commands, specifically through the interpolation of unescaped action parameters into command strings generated by the crowdstrike_rtr.py and endpoint.py modules. The vulnerability allows an attacker to inject malicious payloads directly into file_path, path, script_name, or script_args parameters, thereby bypassing intended input validation mechanisms that rely on simple quoting strategies without proper escaping.
The technical root cause lies in how these specific parameters are processed before being passed to the underlying operating system shell for execution. When a user provides input containing single quotes, such as closing an existing quote and appending additional commands, the resulting command string is malformed from the perspective of safe parsing but valid for shell interpretation. This structural flaw enables the injection of arbitrary commands that break out of their intended argument boundaries. Because these operations are executed with elevated privileges, typically SYSTEM on Windows or root on Linux environments managed by the endpoint protection agent, the impact extends far beyond simple data manipulation to full system compromise.
From an operational perspective, this vulnerability poses a severe risk to organizational security postures. Authenticated users who possess access to the AiSOC interface can exploit this flaw to execute arbitrary commands with the highest level of privilege available on managed endpoints. This capability effectively grants attackers complete control over affected systems, allowing for data exfiltration, lateral movement within the network, installation of persistent backdoors, or destruction of critical system files. The ability to run commands as root or SYSTEM means that standard user-level restrictions and security controls are rendered ineffective against this specific attack vector.
This vulnerability is classified under CWE-78 Improper Neutralization of Special Elements used in an OS Command, which highlights the failure to sanitize inputs before their use in dynamic command construction. In terms of tactical mapping within the MITRE ATT&CK framework, this exploit aligns with T1059 Command and Scripting Interpreter, specifically reflecting techniques where attackers leverage system utilities or scripts to execute malicious code on compromised hosts. The scenario also relates to T1203 Exploitation for Client Execution if the injection triggers a download or execution chain initiated by the user interaction within the AiSOC interface.
Mitigation strategies must prioritize immediate patching of all affected AiSOC instances to version 12.0.0 or later, where these interpolation flaws have been addressed through robust input validation and parameterized command construction techniques. In environments where upgrading is not immediately feasible, administrators should enforce strict role-based access controls to limit who can interact with the actions service and Real Time Response features. Additionally, implementing network segmentation to restrict management traffic from untrusted networks can reduce the attack surface available to potential adversaries seeking to exploit this vulnerability through authenticated sessions.
