CVE-2025-24339 is a medium-severity vulnerability identified in the web application component of Bosch Rexroth AG's ctrlX OS - Device Admin. The vulnerability is classified under CWE-644, which pertains to improper neutralization of HTTP headers for scripting syntax. This flaw allows a remote, unauthenticated attacker to craft malicious HTTP requests that exploit the web application's failure to properly sanitize HTTP headers. As a result, attackers can perform attacks such as web cache poisoning and Man-in-the-Middle (MitM) attacks against users interacting with the vulnerable system. Web cache poisoning can cause malicious content to be served to legitimate users by corrupting cached responses, potentially leading to the execution of malicious scripts or the delivery of manipulated data. MitM attacks facilitated by this vulnerability could intercept or alter communications between users and the device, compromising confidentiality and integrity. The vulnerability affects multiple versions of ctrlX OS - Device Admin, specifically versions 1.12.0, 1.20.0, and 2.6.0. The CVSS v3.1 base score is 5.0, indicating a medium severity level. The vector string (AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:L) shows that the attack can be launched remotely without privileges but requires user interaction and has a high attack complexity. The impact on confidentiality, integrity, and availability is low to limited, but the potential for user-targeted attacks remains significant. No known exploits are currently reported in the wild, and no patches have been linked yet, indicating that mitigation efforts should be proactive. The vulnerability's presence in a critical industrial operating system used for device administration highlights the importance of addressing it promptly to prevent exploitation in industrial control environments.

For European organizations, especially those in industrial automation, manufacturing, and critical infrastructure sectors, this vulnerability poses a tangible risk. Bosch Rexroth's ctrlX OS is widely used in industrial control systems (ICS) and automation devices, which are integral to manufacturing plants, energy grids, and transportation systems across Europe. Exploitation could lead to unauthorized manipulation of device communications, potentially disrupting operational processes or enabling further attacks within industrial networks. Web cache poisoning could mislead users or automated systems into accepting malicious content, increasing the risk of downstream compromise. MitM attacks could expose sensitive operational data or credentials, undermining confidentiality and trust in industrial communications. Given the reliance on these systems for critical operations, even low-level integrity or availability impacts could cascade into significant operational disruptions. The requirement for user interaction somewhat limits the attack vector but does not eliminate risk, especially in environments where operators or administrators access device management interfaces regularly. The medium severity rating suggests that while immediate catastrophic failure is unlikely, the vulnerability could be leveraged as part of a multi-stage attack targeting industrial environments in Europe.

1. Implement strict input validation and sanitization on all HTTP headers within the ctrlX OS web application to neutralize scripting syntax and prevent injection attacks. 2. Employ web application firewalls (WAFs) configured to detect and block anomalous or malformed HTTP requests targeting device admin interfaces. 3. Restrict access to the ctrlX OS Device Admin web interface to trusted networks only, using network segmentation and VPNs to limit exposure to untrusted sources. 4. Educate users and administrators about the risks of interacting with suspicious links or HTTP requests, emphasizing cautious behavior to mitigate the requirement for user interaction exploitation. 5. Monitor network traffic for signs of web cache poisoning or MitM activity, including unexpected cache behavior or certificate anomalies. 6. Apply any vendor-released patches or updates promptly once available, and maintain close communication with Bosch Rexroth for security advisories. 7. Use strong authentication and session management controls to reduce the risk of session hijacking or unauthorized access, even though the vulnerability does not require authentication. 8. Conduct regular security assessments and penetration testing focused on web interfaces of industrial control systems to identify and remediate similar vulnerabilities proactively.
