CVE-2022-40184 is a medium-severity cross-site scripting (XSS) vulnerability identified in the Bosch VIDEOJET multi 4000, a video surveillance product with a web-based configuration interface. The vulnerability arises from improper neutralization of input during web page generation (CWE-79), specifically incomplete filtering of JavaScript code in various configuration fields. An attacker who has administrative credentials can exploit this flaw by injecting malicious JavaScript code into these configuration fields. This stored script is then executed in the browsers of other administrators who access the same configuration options, enabling potential session hijacking, credential theft, or unauthorized actions within the administrative interface. The vulnerability requires administrative privileges and user interaction (an administrator accessing the affected configuration page) to be exploited. The CVSS 3.1 base score is 5.1, reflecting a medium severity level, with attack vector being network-based, high attack complexity, privileges required at the administrative level, and user interaction necessary. The scope is changed, indicating that the vulnerability could affect resources beyond the initially vulnerable component. No known exploits in the wild have been reported, and Bosch has not published specific patches or mitigation details at the time of this report. The vulnerability was reserved in September 2022 and published in October 2022. Given the nature of the device as a security camera system, exploitation could undermine the integrity and confidentiality of surveillance configurations and potentially disrupt availability if administrative sessions are compromised.

For European organizations deploying Bosch VIDEOJET multi 4000 devices, this vulnerability poses a risk primarily to the confidentiality and integrity of their surveillance system configurations. An attacker with administrative credentials could inject malicious scripts that execute in the context of other administrators’ browsers, potentially leading to credential theft, session hijacking, or unauthorized configuration changes. This could result in unauthorized access to video feeds, manipulation of recording settings, or disabling of security functions, thereby compromising physical security monitoring. The requirement for administrative credentials limits the attack surface but insider threats or credential compromise could enable exploitation. The medium severity score reflects a moderate risk; however, in critical infrastructure or high-security environments common in Europe (such as transportation hubs, government buildings, or industrial sites), the impact could be significant. Additionally, the cross-site scripting nature of the vulnerability could be leveraged as part of a broader attack chain targeting networked security devices. The lack of known exploits reduces immediate risk but does not eliminate the threat, especially if attackers develop proof-of-concept code. Organizations relying on these devices should consider the potential for lateral movement or privilege escalation within their security management environments.

To mitigate CVE-2022-40184, European organizations should implement the following specific measures: 1) Restrict administrative access to the Bosch VIDEOJET multi 4000 interface using network segmentation and firewall rules to limit exposure to trusted management networks only. 2) Enforce strong, unique administrative credentials and implement multi-factor authentication (MFA) where possible to reduce the risk of credential compromise. 3) Monitor administrative access logs for unusual activity that could indicate attempts to exploit the vulnerability. 4) Educate administrators about the risk of stored XSS and advise caution when entering configuration data, avoiding unnecessary or suspicious input. 5) Regularly check Bosch’s official channels for firmware updates or patches addressing this vulnerability and apply them promptly once available. 6) Consider deploying web application firewalls (WAFs) or intrusion detection systems (IDS) capable of detecting and blocking malicious script injections targeting the device’s web interface. 7) If feasible, isolate the management interface from general user networks to reduce the risk of cross-site scripting attacks spreading to other systems. 8) Conduct periodic security assessments and penetration testing focused on the management interfaces of security devices to identify and remediate similar vulnerabilities proactively.
