CVE-2025-34160 is an OS command injection vulnerability classified under CWE-78, found in the AnyShare product by Shanghai Aishu Information Technology Co., Ltd. The vulnerability resides in the ServiceAgent API, specifically the /api/ServiceAgent/start_service endpoint accessible on TCP port 10250. This endpoint accepts POST requests containing user-supplied input that is not properly sanitized or neutralized before being passed to the underlying operating system shell. As a result, an attacker can craft malicious payloads containing shell metacharacters or commands that the backend interprets and executes with the privileges of the service. Notably, this vulnerability requires no authentication or user interaction, making it trivially exploitable remotely. The affected versions include all builds prior to August 2025, with the vendor reportedly releasing fixed versions thereafter, though exact version ranges remain unspecified. The vulnerability was publicly disclosed in late August 2025, with exploitation evidence first detected by Shadowserver Foundation in mid-July 2025. The CVSS v4.0 score is 10.0, reflecting the vulnerability's criticality due to its network attack vector, lack of required privileges, and high impact on confidentiality, integrity, and availability. The flaw enables attackers to execute arbitrary commands, potentially leading to full system compromise, data exfiltration, deployment of malware, or pivoting to other internal systems. No official patches or mitigation links were provided in the source data, indicating that organizations must urgently verify their AnyShare deployments and apply vendor updates or implement compensating controls.

For European organizations, the impact of CVE-2025-34160 is severe. AnyShare is an enterprise content collaboration and file sharing platform, often used in sectors requiring secure document management such as finance, healthcare, government, and manufacturing. Exploitation could allow attackers to execute arbitrary commands remotely without authentication, leading to full compromise of affected servers. This can result in unauthorized data access or exfiltration, disruption of critical business processes, deployment of ransomware or other malware, and lateral movement within corporate networks. Given the criticality and ease of exploitation, attackers could rapidly leverage this vulnerability to target sensitive information or disrupt operations. Organizations with AnyShare instances exposed to the internet or insufficiently segmented internal networks face heightened risk. The vulnerability's presence in a widely used collaboration tool increases the potential attack surface across European enterprises, potentially affecting confidentiality, integrity, and availability of critical data and services.

1. Immediate verification of AnyShare versions deployed within the environment is essential; prioritize identifying instances running versions prior to August 2025. 2. Apply vendor-provided patches or updates as soon as they become available to remediate the vulnerability. 3. If patches are not yet available, restrict network access to port 10250 using firewalls or network segmentation to limit exposure of the ServiceAgent API to trusted internal hosts only. 4. Implement strict input validation and filtering at network or application layers to detect and block suspicious payloads targeting the /api/ServiceAgent/start_service endpoint. 5. Monitor network traffic and logs for unusual POST requests to the vulnerable endpoint and signs of command injection attempts. 6. Employ endpoint detection and response (EDR) solutions to detect anomalous command execution or process spawning on AnyShare servers. 7. Conduct thorough security assessments and penetration testing focused on AnyShare deployments to identify residual risks. 8. Educate IT and security teams about the vulnerability and ensure incident response plans include scenarios involving AnyShare compromise. 9. Consider isolating AnyShare servers in dedicated network zones with minimal privileges to reduce potential impact. 10. Maintain up-to-date backups of critical data to enable recovery in case of compromise.
