Vulnerabilities

Lua apps can be deployed, removed, started, reloaded or stopped without authorization via AppManager. This allows an attacker to remove legitimate apps creating a DoS attack, read and write files or load apps that use all features of the product available to a customer.

Unauthenticated CROWN APIs allow access to critical functions. This leads to the accessibility of large parts of the web application without authentication.

The product is vulnerable to pass-the-hash attacks in combination with hardcoded credentials of hidden user levels. This means that an attacker can log in with the hidden user levels and gain full access to the device.

Since the firmware update is not validated, an attacker can install modified firmware on the device. This has a high impact on the availabilty, integrity and confidentiality up to the complete compromise of the device.

Due to missing input validation during one step of the firmware update process, the product is vulnerable to remote code execution. With network access and the user level ”Service”, an attacker can execute arbitrary system commands in the root user’s contexts.

A vulnerability in the .sdd file allows an attacker to read default passwords stored in plain text within the code. By exploiting these plaintext credentials, an attacker can log into affected SICK products as an “Authorized Client” if the customer has not changed the default password.

A vulnerability in the MSC800 allows an unauthenticated attacker to modify the product’s IP address over Sopas ET. This can lead to Denial of Service. Users are recommended to upgrade both MSC800 and MSC800 LFT to version V4.26 and S2.93.20 respectively which fixes this issue.

Authentication Bypass by Capture-replay in SICK Flexi Soft Gateways with Partnumbers 1044073, 1127717, 1130282, 1044074, 1121597, 1099832, 1051432, 1127487, 1069070, 1112296, 1044072, 1121596, 1099830 allows an unauthenticated remote attacker to potentially impact the availability, integrity and confidentiality of the gateways via an authentication bypass by capture-replay.

Insufficient Control Flow Management in RDT400 in SICK APU allows an unprivileged remote attacker to potentially enable hidden functionality via HTTP requests.

Files or Directories Accessible to External Parties in RDT400 in SICK APU allows an unprivileged remote attacker to download various files from the server via HTTP requests.

Modification of Assumed-Immutable Data (MAID) in RDT400 in SICK APU allows an unprivileged remote attacker to make the site unable to load necessary strings via changing file paths using HTTP requests.

Improper Restriction of Excessive Authentication Attempts in RDT400 in SICK APU allows an unprivileged remote attacker to guess the password via trial-and-error as the login attempts are not limited.

Missing Authorization in RDT400 in SICK APU allows an unprivileged remote attacker to modify data via HTTP requests that no not require authentication.

Improper Access Control in SICK APU allows an unprivileged remote attacker to download as well as upload arbitrary files via anonymous access to the FTP server.

A remote unauthorized attacker may connect to the SIM1012, interact with the device and change configuration settings. The adversary may also reset the SIM and in the worst case upload a new firmware version to the device.

The LMS5xx uses weak hash generation methods, resulting in the creation of insecure hashs. If an attacker manages to retrieve the hash, it could lead to collision attacks and the potential retrieval of the password.

A remote unprivileged attacker can intercept the communication via e.g. Man-In-The-Middle, due to the absence of Transport Layer Security (TLS) in the SICK LMS5xx. This lack of encryption in the communication channel can lead to the unauthorized disclosure of sensitive information. The attacker can exploit this weakness to eavesdrop on the communication between the LMS5xx and the Client, and potentially manipulate the data being transmitted.

The LMS5xx uses hard-coded credentials, which potentially allow low-skilled unauthorized remote attackers to reconfigure settings and /or disrupt the functionality of the device.

A remote unprivileged attacker can sent multiple packages to the LMS5xx to disrupt its availability through a TCP SYN-based denial-of-service (DDoS) attack. By exploiting this vulnerability, an attacker can flood the targeted LMS5xx with a high volume of TCP SYN requests, overwhelming its resources and causing it to become unresponsive or unavailable for legitimate users.

SICK MSC800 all versions prior to Version 4.0, the affected firmware versions contain a hard-coded customer account password.
