CVE-2025-24347 is a vulnerability identified in the "Network Interfaces" functionality of the web application component of Bosch Rexroth AG's ctrlX OS - Device Admin. This vulnerability stems from improper validation of the syntactic correctness of input, classified under CWE-1286. Specifically, a remote attacker with low-privileged authenticated access can send crafted HTTP requests to manipulate the network configuration file. The flaw exists in versions 1.12.0, 1.20.0, and 2.6.0 of ctrlX OS - Device Admin. The vulnerability does not require user interaction but does require authentication with low privileges, which lowers the barrier for exploitation within an environment where an attacker has some level of access. The CVSS v3.1 base score is 6.5, indicating a medium severity level. The vector string (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H) shows that the attack is network-based, requires low attack complexity, low privileges, no user interaction, and impacts availability only, with no confidentiality or integrity impact. The vulnerability allows an attacker to manipulate network configuration files, which could lead to denial of service or disruption of network connectivity on the affected device. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability is significant because ctrlX OS is an industrial operating system used in automation and control systems, where network configuration integrity is critical for operational continuity and safety. Improper manipulation of network settings could disrupt industrial processes or cause device unavailability, impacting production lines or critical infrastructure components that rely on Bosch Rexroth automation solutions.

For European organizations, especially those in manufacturing, industrial automation, and critical infrastructure sectors, this vulnerability poses a risk of operational disruption. Bosch Rexroth's ctrlX OS is widely used in industrial control systems (ICS) and automation environments across Europe. An attacker exploiting this vulnerability could alter network configurations, potentially causing denial of service conditions or network isolation of devices, leading to downtime or degraded performance of industrial processes. This could affect production efficiency, safety monitoring, and real-time control systems. Since the vulnerability requires low-privileged authentication, insider threats or compromised credentials could be leveraged to exploit this flaw. The impact is primarily on availability, which in industrial contexts can translate to significant financial losses, safety hazards, and regulatory compliance issues. Furthermore, disruption of network configurations could complicate incident response and recovery efforts. European organizations with extensive Bosch Rexroth deployments in automotive manufacturing, energy production, and factory automation are particularly at risk. The lack of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits over time.

1. Restrict access to the ctrlX OS Device Admin web interface to trusted network segments and enforce strong authentication mechanisms, including multi-factor authentication, to reduce the risk of low-privileged account compromise. 2. Implement network segmentation to isolate industrial control systems from general IT networks and internet-facing systems, minimizing exposure to remote attackers. 3. Monitor and audit network configuration changes on ctrlX OS devices to detect unauthorized modifications promptly. 4. Employ strict input validation and filtering at network boundaries to detect and block malformed HTTP requests targeting the web application. 5. Maintain an up-to-date inventory of all ctrlX OS devices and their versions to prioritize patching once official updates or patches are released by Bosch Rexroth. 6. Develop incident response playbooks specific to network configuration manipulation scenarios to enable rapid containment and recovery. 7. Engage with Bosch Rexroth support channels for early access to patches or workarounds and subscribe to vulnerability advisories. 8. Consider deploying application-layer firewalls or web application firewalls (WAFs) capable of detecting and blocking suspicious HTTP requests targeting the Device Admin interface. 9. Limit the number of users with access to the Device Admin interface and enforce the principle of least privilege to reduce the attack surface. 10. Conduct regular security awareness training for personnel with access to industrial control systems to recognize and report suspicious activities.
