CVE-2025-9846 is a critical vulnerability classified under CWE-434, which pertains to the unrestricted upload of files with dangerous types. This vulnerability affects the Inka.Net product developed by TalentSys Consulting Information Technology Industry Inc., specifically versions before 6.7.1. The core issue is that the application does not properly restrict or validate the types of files that users can upload, allowing an attacker to upload malicious files that can lead to command injection. Command injection vulnerabilities enable attackers to execute arbitrary commands on the underlying server operating system, potentially gaining full control over the affected system. The CVSS v3.1 base score is 10.0, indicating maximum severity, with the vector AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H. This means the attack can be performed remotely over the network without any privileges or user interaction, and it impacts confidentiality, integrity, and availability with a scope change (the vulnerability affects resources beyond the initially vulnerable component). Although no known exploits are currently reported in the wild, the vulnerability’s nature and severity make it a prime target for exploitation once publicly disclosed. The lack of available patches at the time of publication further increases the risk for organizations using vulnerable versions of Inka.Net. In summary, this vulnerability allows an unauthenticated remote attacker to upload malicious files that can execute arbitrary commands on the server, leading to complete system compromise.

For European organizations using Inka.Net, this vulnerability poses a significant risk. Successful exploitation could lead to full system compromise, including unauthorized access to sensitive data, disruption of services, and potential lateral movement within the network. Given Inka.Net’s role in consulting and IT services, compromised systems could expose client data, intellectual property, and internal communications. The critical nature of the vulnerability means attackers can operate without authentication or user interaction, increasing the likelihood of automated attacks and widespread exploitation. This could result in severe operational disruptions, regulatory non-compliance (especially under GDPR due to data breaches), financial losses, and reputational damage. Additionally, the scope change in the CVSS vector suggests that the impact could extend beyond the initial application, affecting other connected systems and services within an organization’s infrastructure. The absence of patches at the time of disclosure means organizations must act quickly to mitigate risk, as threat actors may develop exploits rapidly.

1. Immediate mitigation should include restricting or disabling file upload functionality in Inka.Net until a patch is available. 2. Implement network-level controls such as web application firewalls (WAFs) with custom rules to detect and block malicious file upload attempts and command injection patterns. 3. Employ strict input validation and file type verification on the server side, ensuring only allowed file types are accepted and scanned for malicious content. 4. Monitor logs for unusual file upload activity and command execution attempts, enabling rapid detection and response. 5. Isolate the Inka.Net server from critical internal networks to limit potential lateral movement in case of compromise. 6. Regularly update and patch Inka.Net as soon as the vendor releases a fix for this vulnerability. 7. Conduct a thorough security review of all file upload mechanisms in the environment to identify and remediate similar risks. 8. Educate IT and security teams about this vulnerability and ensure incident response plans are updated to handle potential exploitation scenarios.
