CVE-2020-6776 in PRAESIDEO
Summary
by MITRE • 01/14/2021
A vulnerability in the web-based management interface of Bosch PRAESIDEO until and including version 4.41 and Bosch PRAESENSA until and including version 1.10 allows an unauthenticated remote attacker to trigger actions on an affected system on behalf of another user (Cross-Site Request Forgery). This requires the victim to be tricked into clicking a malicious link or submitting a malicious form. A successful exploit allows the attacker to perform arbitrary actions with the privileges of the victim, e.g. creating and modifying user accounts, changing system configuration settings and cause DoS conditions. Note: For Bosch PRAESIDEO 4.31 and newer and Bosch PRAESENSA in all versions, the confidentiality impact is considered low because user credentials are not shown in the web interface.

Analysis

This vulnerability represents a critical cross-site request forgery flaw in Bosch security management systems that affects multiple versions of both PRAESIDEO and PRAESENSA platforms. The vulnerability exists within the web-based management interface of these security solutions, creating a significant risk for organizations relying on these systems for physical security management. The flaw allows unauthenticated remote attackers to manipulate system operations by tricking legitimate users into executing malicious requests, essentially enabling attackers to perform unauthorized actions on behalf of authenticated users. This type of vulnerability falls under the CWE-352 category, which specifically addresses cross-site request forgery issues in web applications, making it a well-documented and serious security concern within the cybersecurity community.
The technical implementation of this vulnerability exploits the lack of proper request validation mechanisms within the web interface. When a victim user accesses a maliciously crafted link or submits a malicious form, the system processes the request without sufficient authentication verification or anti-CSRF token validation. This allows an attacker to leverage the victim's existing session and privileges to execute arbitrary commands within the system. The attack vector requires social engineering to convince the victim to interact with the malicious content, but once triggered, the consequences can be severe. The vulnerability affects system configuration changes, user account manipulation, and can potentially lead to denial of service conditions, demonstrating the broad impact scope of such a flaw in security infrastructure.
The operational impact of this vulnerability extends beyond simple unauthorized access, as it can compromise the integrity and availability of critical security systems. Organizations using affected versions of these Bosch platforms face potential unauthorized modifications to security configurations, creation of malicious user accounts, and disruption of normal system operations. The vulnerability's presence in both PRAESIDEO and PRAESENSA platforms indicates a systemic issue within the web interface architecture of these security solutions, potentially affecting multiple deployment scenarios including enterprise security systems, building access control, and surveillance management. The fact that user credentials are not displayed in newer versions of PRAESIDEO 4.31 and newer suggests some mitigation efforts were implemented, but the core CSRF vulnerability remains exploitable.
Mitigation strategies for this vulnerability should include immediate implementation of anti-CSRF token mechanisms within the web interface, proper session management controls, and comprehensive user education regarding suspicious links and forms. Organizations should upgrade to the latest available versions of both platforms where the vulnerability has been addressed, and implement network segmentation to limit exposure. The ATT&CK framework categorizes this vulnerability under the T1213 technique for credential access, while also relating to T1499 for network disruption and system compromise. Additional defensive measures include web application firewalls, regular security assessments, and monitoring for unauthorized configuration changes. Given the critical nature of security infrastructure, organizations should conduct thorough vulnerability assessments and implement layered security controls to prevent exploitation of such remote code execution and privilege escalation vulnerabilities.
