CVE-2026-92980 in HortusFox-Web
Summary
by MITRE • 09/17/2026
HortusFox-Web prior to version 6.1 contains a remote code execution vulnerability that allows authenticated administrators to execute arbitrary OS commands as the web server user by abusing the Import/Export functionality. Attackers can leverage the Import/Export feature, which is intended solely for data portability, to deploy and execute malicious code on the underlying application server host.

The vulnerability identified in HortusFox-Web prior to version 6.1 represents a critical remote code execution flaw that stems from improper input validation within the application's Import/Export functionality. Although this feature is designed strictly for data portability, allowing administrators to move configuration and operational data between instances, it fails to adequately sanitize or validate uploaded files before processing them on the server side. This architectural oversight creates a pathway for authenticated users with administrative privileges to inject malicious payloads into the system. The core technical flaw lies in the application's handling of file uploads, where it does not sufficiently restrict the types of content that can be processed or executed during the import operation. By exploiting this weakness, an attacker who has obtained valid administrator credentials can craft a specially formatted request containing executable code disguised as legitimate data. When the system processes this malicious input through its export mechanism, it inadvertently executes the embedded commands within the context of the web server process.
From a technical perspective, this vulnerability is classified under CWE-94 Improper Control of Generation of Code or Command, commonly referred to as injection. The specific nature of the attack involves command injection where user-controlled data influences the execution of system-level commands without proper isolation or sanitization. This aligns with MITRE ATT&CK technique T1059 Command and Scripting Interpreter, specifically through mechanisms that allow for arbitrary code execution via application features rather than direct shell access. The severity is compounded by the fact that it requires authentication, which might suggest a lower risk to some defenders; however, in many enterprise environments, administrative credentials can be compromised through phishing, credential stuffing, or lateral movement from other breached systems. Once an attacker gains this level of access and exploits the vulnerability, they achieve code execution with the privileges of the web server user. This is often equivalent to SYSTEM on Windows-based deployments or root-level capabilities depending on how the service is configured in Linux environments, providing a significant foothold for further exploitation.
The operational impact of this vulnerability extends far beyond simple data integrity issues. An attacker leveraging this flaw can deploy backdoors, install malware, exfiltrate sensitive database contents, or pivot to other systems within the internal network. Because the execution occurs under the web server user account, the potential for privilege escalation is high if that account has broader system permissions than intended. This could lead to a complete compromise of the underlying application server host, disrupting business operations and exposing critical intellectual property or customer data. The ability to execute arbitrary OS commands means that attackers are not limited to the confines of the web application but can interact directly with the operating system, modifying files, creating new user accounts, or disabling security controls such as firewalls or antivirus software. This transforms a localized application flaw into a severe infrastructure-level threat requiring immediate attention and remediation.
To mitigate this risk, organizations running HortusFox-Web versions prior to 6.1 must apply the vendor-provided patch immediately upon availability. Until the update is applied, administrators should consider implementing strict network segmentation to limit access to the administrative interface of the application from untrusted networks. Additionally, enforcing multi-factor authentication for all administrator accounts can reduce the likelihood of credential compromise that leads to exploitation. Input validation controls at a WAF level may also help detect and block attempts to exploit this vulnerability by identifying anomalous patterns in upload requests or command injection signatures. Regular auditing of administrative access logs is recommended to identify any unauthorized import/export activities that might indicate an ongoing attack attempt. Ultimately, the most effective defense remains timely patching combined with robust identity management practices to ensure that only legitimate administrators can interact with sensitive system functions.
