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 characters in the pureftpd.passwd file during a username change, which in turn allows for bypassing chroot restrictions in the FTP server. An attacker can simply send an HTTP request to the device to trigger this vulnerability.

Security readout for executives and security teams

CVE-2017-2850 affects Foscam C1 Indoor HD cameras. A low-privileged attacker who can reach the web management interface can abuse username-change handling to weaken FTP isolation. That can expose files the FTP service should confine, creating high confidentiality, integrity, and availability risk for affected cameras. Exposure is most likely where Foscam C1 Indoor IP cameras run application firmware 2.52.2.37 and the management interface is reachable by users or networks that should not administer the device. The source bundle does not prove broader firmware impact. Prioritize remediation for internet-reachable or broadly accessible cameras. The issue can undermine FTP confinement and potentially expose or alter camera data, but evidence provided here does not show active exploitation. Mitigation focus: Identify Foscam C1 cameras and their application firmware versions.; Restrict web management and FTP access to trusted administration networks only.; Disable FTP if it is not operationally required..
