#vulnerability

An issue was discovered on Epson Expression Home XP255 20.08.FM10I8 devices. POST requests do not require anti-CSRF tokens or other mechanisms for validating that the request is from a legitimate source. In addition, CSRF attacks can be used to send text directly to the RAW printer interface. For example, an attack could deliver a worrisome printout to an end user.

An issue was discovered on Epson Expression Home XP255 20.08.FM10I8 devices. With the SNMPv1 public community, all values can be read, and with the epson community, all the changeable values can be written/updated, as demonstrated by permanently disabling the network card or changing the DNS servers.

An issue was discovered on Epson Expression Home XP255 20.08.FM10I8 devices. By default, the device comes (and functions) without a password. The user is at no point prompted to set up a password on the device (leaving a number of devices without a password). In this case, anyone connecting to the web admin panel is capable of becoming admin without using any credentials.

An issue was discovered on Brother MFC-J491DW C1806180757 devices. The printer's web-interface password hash can be retrieved without authentication, because the response header of any failed login attempt returns an incomplete authorization cookie. The value of the authorization cookie is the MD5 hash of the password in hexadecimal. An attacker can easily derive the true MD5 hash from this, and use offline cracking attacks to obtain administrative access to the device.

An issue was discovered on Sannce Smart HD Wifi Security Camera EAN 2 950004 595317 devices. It is possible (using TELNET without a password) to control the camera's pan/zoom/tilt functionality.

An issue was discovered on Sannce Smart HD Wifi Security Camera EAN 2 950004 595317 devices. By default, a mobile application is used to stream over UDP. However, the device offers many more services that also enable streaming. Although the service used by the mobile application requires a password, the other streaming services do not. By initiating communication on the RTSP port, an attacker can obtain access to the video feed without authenticating.

An issue was discovered on Sannce Smart HD Wifi Security Camera EAN 2 950004 595317 devices. The device by default has a TELNET interface available (which is not advertised or functionally used, but is nevertheless available). Two backdoor accounts (root and default) exist that can be used on this interface. The usernames and passwords of the backdoor accounts are the same on all devices. Attackers can use these backdoor accounts to obtain access and execute code as root within the device.

An issue was discovered on Sannce Smart HD Wifi Security Camera EAN 2 950004 595317 devices. A crash and reboot can be triggered by crafted IP traffic, as demonstrated by the Nikto vulnerability scanner. For example, sending the 111111 string to UDP port 20188 causes a reboot. To deny service for a long time period, the crafted IP traffic may be sent periodically.

An issue was discovered in SeTracker2 for TK-Star Q90 Junior GPS horloge 3.1042.9.8656 devices. It has unnecessary permissions such as READ_EXTERNAL_STORAGE, WRITE_EXTERNAL_STORAGE, and READ_CONTACTS.

An issue was discovered on TK-Star Q90 Junior GPS horloge 3.1042.9.8656 devices. When using the device at initial setup, a default password is used (123456) for administrative purposes. There is no prompt to change this password. Note that this password can be used in combination with CVE-2019-20470.
