CVE-2025-34160 in AnyShare
Summary
by MITRE • 08/28/2025
AnyShare contains a critical unauthenticated remote code execution vulnerability in the ServiceAgent API exposed on port 10250. The endpoint /api/ServiceAgent/start_service accepts user-supplied input via POST and fails to sanitize command-like payloads. An attacker can inject shell syntax that is interpreted by the backend, enabling arbitrary command execution. The vulnerability is presumed to affect builds released prior to August 2025 and is said to be remediated in newer versions of the product, though the exact affected range remains undefined.

The vulnerability CVE-2025-34160 represents a critical security flaw in the AnyShare platform that exposes a remote code execution capability through an improperly secured API endpoint. This vulnerability specifically targets the ServiceAgent API component that operates on port 10250, which serves as a critical interface for system operations. The attack vector is particularly concerning as it requires no authentication, making it accessible to any external party with network access to the affected system. The vulnerability resides in the /api/ServiceAgent/start_service endpoint which processes POST requests containing user-supplied data without adequate input validation or sanitization mechanisms. This design flaw creates a direct pathway for malicious actors to inject arbitrary shell commands that are subsequently executed by the backend system with the privileges of the running service account.
The technical exploitation of this vulnerability follows a well-established pattern that aligns with CWE-77 and CWE-94, representing command injection and code injection flaws respectively. When an attacker submits a malicious payload to the vulnerable endpoint, the system fails to properly sanitize the input before processing, allowing shell metacharacters and command syntax to be interpreted and executed by the underlying operating system. This creates a scenario where an attacker can execute arbitrary system commands, potentially gaining complete control over the affected server. The vulnerability's classification as unauthenticated means that threat actors do not require valid credentials to exploit this weakness, significantly increasing its attack surface and potential impact. The fact that this vulnerability affects builds released prior to August 2025 suggests a prolonged window of exposure, during which organizations may have remained unaware of the security risk.
The operational impact of this vulnerability extends beyond simple privilege escalation, as it provides attackers with the capability to perform comprehensive system compromise operations. An attacker could leverage this vulnerability to establish persistent access, escalate privileges, exfiltrate sensitive data, or deploy additional malware payloads. The ServiceAgent API's role in system operations makes it particularly valuable as an attack entry point, as successful exploitation could enable attackers to manipulate core system services and potentially compromise the entire platform. Organizations running affected versions of AnyShare face significant risk of data breaches, system compromise, and potential regulatory compliance violations, particularly in environments where sensitive information is processed. The vulnerability's remediation status indicates that newer versions have addressed the input sanitization issues, but the undefined affected version range creates uncertainty for organizations attempting to assess their risk exposure.
Mitigation strategies for CVE-2025-34160 should prioritize immediate action to upgrade to patched versions of AnyShare, as recommended by the vendor's security advisories. Network segmentation and firewall rules should be implemented to restrict access to port 10250, limiting exposure to trusted networks only. Organizations should also consider implementing web application firewalls or intrusion detection systems to monitor for suspicious payloads targeting the vulnerable endpoint. Input validation and sanitization should be enhanced at the application layer to prevent similar vulnerabilities from occurring in other components. Security teams should conduct comprehensive vulnerability assessments to identify any other potentially exposed API endpoints that may share similar design flaws. The ATT&CK framework categorizes this vulnerability under T1059.001 for command and scripting interpreter, highlighting the need for comprehensive monitoring of command execution activities and implementing principle of least privilege access controls to minimize potential damage from successful exploitation attempts.
