CVE-2017-2848 in C1 Indoor HD Camera
Summary
by MITRE
In the web management interface in Foscam C1 Indoor HD cameras with application firmware 2.52.2.37, a specially crafted HTTP request can allow for a user to inject arbitrary shell characters during manual network configuration resulting in command injection. An attacker can simply send an HTTP request to the device to trigger this vulnerability.

The CVE-2017-2848 vulnerability affects Foscam C1 Indoor HD security cameras running firmware version 2.52.2.37, presenting a critical command injection flaw within the device's web management interface. This vulnerability stems from inadequate input validation mechanisms in the network configuration handling component of the camera's web server implementation. The flaw specifically manifests when the device processes manual network configuration parameters through HTTP requests, creating an avenue for malicious actors to inject shell commands directly into the system's command execution pipeline.
The technical exploitation of this vulnerability occurs through carefully crafted HTTP requests that manipulate the network configuration parameters passed to the camera's underlying operating system. When the device processes these malformed requests, it fails to properly sanitize or validate the input data before incorporating it into system commands, allowing attackers to execute arbitrary shell commands with the privileges of the web server process. This command injection vulnerability falls under CWE-77 which specifically addresses command injection flaws in software systems. The attack vector is particularly concerning because it requires no authentication to exploit, making it accessible to anyone who can reach the device's web management interface over the network.
The operational impact of this vulnerability extends beyond simple unauthorized command execution, as it provides attackers with complete control over the affected camera device. Successful exploitation enables attackers to modify network settings, extract sensitive configuration data, install malicious software, or even use the compromised camera as a pivot point for further attacks within the local network. The vulnerability's accessibility through standard HTTP protocols means that attackers can leverage automated scanning tools to identify and exploit multiple devices simultaneously, potentially leading to large-scale compromise of security camera networks. This aligns with ATT&CK technique T1059.001 for command and scripting interpreter, where adversaries use legitimate system tools to execute malicious commands.
Mitigation strategies for CVE-2017-2848 require immediate firmware updates from Foscam to address the input validation deficiencies in the web management interface. Organizations should also implement network segmentation to isolate security cameras from critical network segments and deploy network monitoring solutions to detect suspicious HTTP traffic patterns. Additional protective measures include disabling unnecessary web management interfaces when not required, implementing strong access controls with complex credentials, and regularly auditing network configurations to identify unauthorized changes. The vulnerability demonstrates the critical importance of input validation in embedded systems and highlights the need for robust security testing of network management interfaces in IoT devices. Organizations should also consider deploying intrusion detection systems specifically configured to monitor for command injection patterns in their security camera networks.
