CVE-2013-3689 in 100ap Device
Summary
by MITRE
Brickcom FB-100Ap, WCB-100Ap, MD-100Ap, WFB-100Ap, OB-100Ae, OSD-040E, and possibly other camera models with firmware 3.0.6.16C1 and earlier, do not properly restrict access to configfile.dump, which allow remote attackers to obtain sensitive information (user names, passwords, and configurations) via a get action.

The vulnerability identified as CVE-2013-3689 affects several Brickcom network camera models including FB-100Ap, WCB-100Ap, MD-100Ap, WFB-100Ap, OB-100Ae, and OSD-040E devices running firmware versions 3.0.6.16C1 and earlier. This represents a critical access control flaw that undermines the security posture of these surveillance devices. The vulnerability stems from improper access restrictions on the configfile.dump file, which contains sensitive configuration data including user credentials and system parameters. The flaw allows remote attackers to exploit a get action to retrieve this information without proper authentication, creating a significant risk for organizations relying on these cameras for security monitoring.
The technical implementation of this vulnerability demonstrates a classic path traversal and privilege escalation issue that aligns with CWE-22 Path Traversal and CWE-285 Improper Authorization. Attackers can remotely access the configfile.dump file through a simple HTTP GET request, bypassing normal authentication mechanisms that should protect sensitive system configuration data. This flaw represents a fundamental failure in the camera's access control implementation, where the device fails to properly validate user permissions before allowing access to critical configuration files. The vulnerability exists in the web interface component of these devices, where the get action handler does not properly enforce access controls, allowing any remote user to retrieve sensitive information.
The operational impact of this vulnerability extends beyond simple credential theft, as it provides attackers with comprehensive system configuration data that can be used for further exploitation. When attackers obtain the configfile.dump file, they gain access to administrative usernames and passwords, network configuration parameters, and potentially other sensitive system information. This information can be leveraged to conduct additional attacks including network reconnaissance, lateral movement within the organization's infrastructure, and privilege escalation attacks. The exposure of default credentials or weak authentication settings in these files could allow attackers to maintain persistent access to the network surveillance infrastructure. Organizations may face significant operational disruption when these cameras are compromised, as attackers can potentially disable security features, modify configurations, or use the cameras as entry points for broader network attacks.
Mitigation strategies for CVE-2013-3689 should prioritize immediate firmware updates from Brickcom to address the access control vulnerability. Organizations must also implement network segmentation to isolate these devices from critical systems and apply network access controls to restrict communication with the affected cameras. Security monitoring should be enhanced to detect unauthorized access attempts to configuration files, and regular security audits should verify that sensitive configuration data is not exposed through web interfaces. The ATT&CK framework categorizes this vulnerability under T1078 Valid Accounts and T1046 Network Service Scanning, as attackers can use the retrieved credentials to establish persistent access and scan network services. Additionally, implementing principle of least privilege for web interface access and disabling unnecessary services can reduce the attack surface, while regular vulnerability assessments should be conducted to identify similar access control flaws in other networked devices.
