Researchers at F-Secure documented eighteen vulnerabilities that the manufacturer has nonetheless to mend despite being alerted to them many months ago. All of the issues were confirmed during a camera marketed under the Opticam i5 HD brand. A smaller range of the vulnerabilities was conjointly found within the Foscam C2. The report aforesaid the weaknesses are seemingly to exist in several different camera models Foscam manufactures and sells under different complete names.
F-Secure researchers wrote:
The sheer variety of vulnerabilities offers an attacker multiple alternatives in compromising the device. Among the discovered vulnerabilities are insecure default credentials and hard-coded credentials, each of that build it trivial for an attacker to achieve unauthorized access. different vulnerabilities give remote command injection by a wrongdoer. World-writeable files and directories permit an attacker to change the code and to achieve root privileges. Hidden Telnet practicality permits an attacker to use Telnet to find extra vulnerabilities within the device and inside the surrounding network. additionally, the device’s “firewall” doesn’t behave as a firewall, and it also discloses info concerning the validity of credentials.
The flaws give a large range of hacks, together with using the Internet-connected cameras to participate with different infected devices in distributed denial-of-service attacks, accessing non-public videos, and compromising different devices connected to the same local network. The vulnerabilities are combined by the power to permanently replace the conventional firmware controlling the camera with malicious computer code that may survive restarts without being detected.
One example of 3 vulnerabilities disclosed within the report: each camera models have (1) a inherent file transfer protocol server that contains a hard-coded account parole (an empty parole, by the way) that cannot be modified by the user, (2) a hidden and undocumented telnet perform that enables attackers to expand the device capabilities, and (3) incorrect permissions appointed to programming scripts that run anytime the device starts.
Hackers may exploit all 3 of those flaws during an approach “to permit the wrongdoer persistent remote access to the device,” the report explained. “The empty parole on the FTP user account may be want to log in. The hidden Telnet practicality will then be activated. After this, the wrongdoer will access the world-writable (non-restricted) file that controls that programs run on boot, and also the wrongdoer could add his own to the list. this enables the wrongdoer persistent access, notwithstanding the device is rebooted. In fact, the attack needs the device to be rebooted, however, there’s some way to force a bring up similarly.”
