CVE-2026-60041 in mbCONNECT24
Summary
by MITRE • 11/10/2026
An unauthenticated remote attacker can perform a CSRF attack on a logged in backend user allowing for execution of multiple critical system actions. This could allow an attacker to shutdown the server or restore an uploaded backup. This can result in a loss of integrity and availability.

The vulnerability described constitutes a Critical Cross-Site Request Forgery (CSRF) flaw affecting the administrative backend interface of the target application. In this scenario, an unauthenticated remote attacker exploits the lack of proper anti-CSRF protections to trick a legitimate, authenticated administrator into performing unintended actions. The core technical failure lies in the absence of unique, secret tokens or strict origin validation mechanisms within state-changing HTTP requests submitted by the frontend client. Because modern browsers automatically attach session cookies and authentication credentials to cross-origin requests initiated via forms or scripts controlled by an attacker, the server erroneously treats these maliciously crafted requests as legitimate user interactions. This fundamental breakdown in security logic allows any external party with a web browser capable of making HTTP requests to impersonate an authenticated backend user without requiring prior access to their session tokens or credentials.
The operational impact of this vulnerability is severe due to the high privilege level associated with the targeted backend users and the critical nature of the affected functions. Specifically, the attacker can force the execution of system shutdown commands, which directly compromises the availability of the service by causing a denial of service condition for all legitimate users. Furthermore, the ability to restore an uploaded backup introduces significant integrity risks. If the application allows backups from unverified sources or if previous uploads were compromised, restoring such data could reintroduce malware, backdoors, or corrupted configurations into the live environment. This dual threat vector ensures that both the confidentiality and availability aspects of the CIA triad are jeopardized, although the primary immediate effects manifest as integrity violations through unauthorized configuration changes and availability disruptions via server termination.
From a classification perspective, this vulnerability aligns with CWE-352: Cross-Site Request Forgery (CSRF), which describes situations where an application uses user-supplied input without proper validation to perform state-changing actions. The attack methodology maps directly to the MITRE ATT&CK technique T1078: Valid Accounts, specifically under the sub-technique of using stolen or forged credentials via social engineering or automated exploitation scripts that leverage existing valid sessions. Additionally, the impact on system availability relates to CWE-400: Uncontrolled Resource Consumption if the shutdown causes resource exhaustion for recovery efforts, while the restoration action may involve CWE-798: Use of Hard-coded Credentials if the backup process relies on embedded secrets. The lack of verification for request origin and token integrity represents a fundamental deviation from secure coding standards such as OWASP Top 10 A05:2021 Security Misconfiguration or A07:2021 Identification and Authentication Failures, depending on how session management is implemented across the application stack.
To mitigate this vulnerability, immediate remediation steps must focus on implementing robust anti-CSRF mechanisms at both the framework level and within custom code. The primary defense involves generating unique, unpredictable CSRF tokens for each user session and embedding them in all state-changing forms or API requests as hidden fields or headers. These tokens must be validated server-side against the current session identifier before processing any request that modifies system state. Additionally, implementing SameSite cookie attributes set to Strict or Lax can prevent browsers from sending cookies on cross-site requests, providing a strong browser-level defense in addition to token-based validation. It is also advisable to enforce re-authentication for sensitive administrative actions such as server shutdowns or data restoration operations, ensuring that even if an attacker initiates the request flow, they cannot complete it without fresh proof of identity. Regular security audits and static application security testing (SAST) should be integrated into the development lifecycle to detect similar patterns in other parts of the backend interface before deployment.
