Impact

Complete system compromise — the attacker gains the ability to install malware, steal data, create backdoors, or pivot to other systems on the network.

Exploit ScenarioDerived

An attacker sends a specially crafted request to the vulnerable service that triggers code execution with the privileges of the running process.

Emergency Immediate action required. Why: CRITICAL + EPSS > 30%, no patch available.

AnalysisAIv1 – Mar 16, 2026

An unauthenticated remote code execution vulnerability exists in Remote for Mac, a macOS remote control utility developed by Aexol Studio, in versions up to and including 2025.7. When the application is configured with authentication disabled (i.e., the "Allow unknown devices" option is enabled), the /api/executeScript endpoint is exposed without access control. This allows unauthenticated remote attackers to inject arbitrary AppleScript payloads via the X-Script HTTP header, resulting in code execution using do shell script. Successful exploitation grants attackers the ability to run arbitrary commands on the macOS host with the privileges of the Remote for Mac background process.

Executive ViewAI

Why It Matters

Organizations using versions face critical risk from CVE-2025-34089, a code injection vulnerability rated CVSS 9.3. Successful exploitation could allow attackers to execute arbitrary code or commands on affected systems, potentially leading to full system compromise. With an EPSS score of 56%, this vulnerability faces very high likelihood of exploitation. Organizations should apply vendor updates immediately when available and implement compensating controls in the interim.

Business Impact: Severe
Compensating Controls

Apply vendor patch. If immediate patching is not feasible: (1) Deploy WAF rules to block injection patterns; (2) Restrict network access to affected components; (3) Enable enhanced logging for suspicious activity.

Attack Technique

Code Injection CRITICAL

Code injection occurs when an application accepts user input and passes it directly into a language interpreter or evaluator without proper sanitization.

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
