CVE-2026-95649 in IRISPowerscan
Summary
by MITRE • 11/04/2026
IRISPowerscan insufficiently restrict the use of untrusted scripts. An authenticated user with access to script functionality can import or modify scripts that are executed by the application, potentially resulting in arbitrary code execution in the security context of the Windows user running IRISPowerscan.

The vulnerability identified as an Insufficiently Restricting Untrusted Scripts flaw within IRISPowerscan represents a critical failure in input validation and access control mechanisms. This issue stems from the application's inability to properly sanitize or validate scripts that are imported or modified by authenticated users who possess specific functional permissions. In secure software architecture, any component that allows user-driven modification of executable logic must implement rigorous checks to ensure that only trusted, authorized code is permitted execution. The absence of these safeguards creates a direct pathway for attackers to inject malicious payloads into the application's operational environment. By leveraging this weakness, an attacker can manipulate the script processing subsystem to execute arbitrary commands, effectively bypassing intended security boundaries and gaining control over critical system functions.
From a technical perspective, the core flaw lies in the lack of strict separation between user-modifiable content and executable code contexts. When an authenticated user imports or alters scripts, the application fails to verify the integrity or origin of these inputs before passing them to the execution engine. This behavior aligns with CWE-94 Improper Control of Generation of Code (Code Injection), where untrusted data is used to direct the construction of dynamic code. Furthermore, it reflects CWE-732 Incorrect Permission Assignment for Critical Resource, as the system grants write or execute privileges to resources that should be restricted to privileged administrators only. The vulnerability exploits the trust relationship between the application and its authenticated users, assuming that any user with script access is acting in good faith, which is a dangerous assumption in multi-user environments where privilege escalation risks are significant.
The operational impact of this vulnerability is severe due to the context in which IRISPowerscan typically operates. The flaw allows for arbitrary code execution within the security context of the Windows user account running the application process. If the service or application runs with elevated privileges, such as Administrator rights or specific system-level permissions, a successful exploitation could lead to complete compromise of the host operating system. An attacker could install backdoors, exfiltrate sensitive data, modify system configurations, or use the compromised machine as a pivot point for further attacks within the network. This level of access undermines the confidentiality, integrity, and availability of both the application itself and any resources accessible by that user account. The ability to execute code remotely if authentication can be bypassed or credentials are stolen amplifies the risk significantly.
In terms of threat modeling, this vulnerability maps directly to MITRE ATT&CK techniques involving command and script interpretation as well as lateral movement via remote services. Specifically, it relates to T1059 Command and Scripting Interpreter, where attackers use scripts like PowerShell, Python, or batch files to execute malicious actions. It also touches upon T1068 Exploitation for Privilege Escalation if the execution context allows moving from a lower-privilege user account to higher privileges through system-level exploits facilitated by the injected code. The attack vector typically involves an authenticated user accessing the script management interface, uploading or editing a malicious script, and triggering its execution either automatically upon import or manually via application features that process these scripts.
Mitigation strategies must focus on implementing strict input validation and enforcing principle of least privilege. Developers should ensure that all inputs related to script content are sanitized against known injection patterns and validated for expected formats before being processed by the interpreter. Implementing a whitelist approach for allowed characters, functions, or libraries within user-defined scripts can significantly reduce the attack surface. Additionally, restricting who has permission to import or modify executable scripts is crucial; this functionality should be limited to high-privilege administrators rather than general authenticated users. Running IRISPowerscan with minimal required permissions in production environments will limit the potential damage if exploitation occurs. Regular security audits and code reviews focusing on dynamic code execution paths are essential to identify similar flaws before they can be exploited in live systems.
