Siemens Desigo PXM Devices
There exists an Improper Neutralization of Special Elements used in an OS Command with root privileges during a restore operation due to the missing validation of the names of files included in the input package. By restoring a specifically crafted package, a remote low-privileged attacker can execute arbitrary system commands with root privileges on the device, leading to a full compromise. Endpoints of the “Operation” web application that interpret and execute Axon language queries allow file read access to the device file system with root privileges. By supplying specific I/O related Axon queries, a remote low-privileged attacker can read sensitive files on the device. Improper Neutralization of Input During Web Page Generation exists in the “Import Files“ functionality of the “Operation” web application, due to the missing validation of the titles of files included in the input package. By uploading a specifically crafted graphics package, a remote low-privileged attacker can execute arbitrary JavaScript code. A Cross-Site Request Forgery exists in endpoints of the “Operation” web application that interpret and execute Axon language queries, due to the missing validation of anti-CSRF tokens or other origin checks. By convincing a victim to click on a malicious link or visit a specifically crafted webpage while logged-in to the device
web application, a remote unauthenticated attacker can execute arbitrary Axon queries against the device. A Cross-Site Request Forgery exists in the “Import Files“ functionality of the “Operation” web application due to the missing validation of anti-CSRF tokens or other origin checks. A remote unauthenticated attacker can upload and enable permanent arbitrary JavaScript code into the device just by convincing a victim to visit a specifically crafted webpage while logged-in to the device web application. The device embedded browser does not prevent interaction with alternative URI schemes when redirected to corresponding resources by web application code. By setting the homepage URI, the favorite URIs, or redirecting embedded browser users via JavaScript code to alternative scheme resources, a remote low privileged attacker can perform a range of attacks against the device, such as read arbitrary files on the filesystem, execute arbitrary JavaScript code in order to steal or manipulate the information on the screen, or trigger denial of service conditions. The device embedded Chromium-based browser is launched as root with the “--no-sandbox” option. Attackers can add arbitrary JavaScript code inside “Operation” graphics and successfully exploit any number of publicly known vulnerabilities against the version of the embedded Chromium-based browser.
