CVE-2026-101290 is a high-severity vulnerability in the SICK AG Sick_Safetyscanners_Base CPP Driver. A remote attacker can send a specially crafted network packet that triggers an out-of-bounds memory read due to improper validation of packet length. This flaw can cause the application to crash, resulting in a denial-of-service condition. No confidentiality or integrity impact is indicated. The affected versions are from 0 up to and including 1.0.4.

An attacker may achieve arbitrary code execution on a target system by uploading a malicious device driver package, bypassing driver verification mechanisms, and triggering the execution of attacker-controlled code. User interaction is required.

An attacker may perform unauthenticated read and write operations on sensitive filesystem areas via the AppEngine Fileaccess over HTTP due to improper access restrictions. A critical filesystem directory was unintentionally exposed through the HTTP-based file access feature, allowing access without authentication. This includes device parameter files, enabling an attacker to read and modify application settings, including customer-defined passwords. Additionally, exposure of the custom application directory may allow execution of arbitrary Lua code within the sandboxed AppEngine environment.

Additionally, exposure of the custom application directory may allow execution of arbitrary Lua code within the sandboxed AppEngine environment.

An attacker may access restricted filesystem areas on the device via the CROWN REST interface due to incomplete whitelist enforcement. Certain directories intended for internal testing were not covered by the whitelist and are accessible without authentication. An unauthenticated attacker could place a manipulated parameter file that becomes active after a reboot, allowing modification of critical device settings, including network configuration and application parameters.

An attacker may exploit the use of outdated and weak MAC algorithms in the device’s SSH service to potentially compromise the integrity of the SSH session, allowing manipulation of transmitted data if the attacker can interact with the network traffic.

An attacker may exploit the use of weak CBC-based cipher suites in the device’s SSH service to potentially observe or manipulate parts of the encrypted SSH communication, if they are able to intercept or interact with the network traffic.

Certain error messages returned by the application expose internal system details that should not be visible to end users, providing attackers with valuable reconnaissance information (like file paths, database errors, or software versions) that can be used to map the application's internal structure and discover other, more critical vulnerabilities.

The application discloses all used components, versions and license information to unauthenticated actors, giving attackers the opportunity to target known security vulnerabilities of used components.

Certain requests pass the authentication token in the URL as string query parameter, making it vulnerable to theft through server logs, proxy logs and Referer headers, which could allow an attacker to hijack the user's session and gain unauthorized access.

An attacker with administrative access may inject malicious content into the login page, potentially enabling cross-site scripting (XSS) attacks, leading to the extraction of sensitive data.

An attacker may exploit missing protection against clickjacking by tricking users into performing unintended actions through maliciously crafted web pages, leading to the extraction of sensitive data.

Improper input handling in a system endpoint may allow attackers to overload resources, causing a denial of service.

An attacker with low privileges may be able to trigger critical system functions such as reboot or factory reset without proper restrictions, potentially leading to service disruption or loss of configuration.

An attacker with low privileges may be able to read files from specific directories on the device, potentially exposing sensitive information.

An attacker with limited permissions may still be able to write files to specific locations on the device, potentially leading to system manipulation.

Improper handling of a URL parameter may allow attackers to execute code in a user's browser after login. This can lead to the extraction of sensitive data.

Improper validation of a login parameter may allow attackers to redirect users to malicious websites after authentication. This can lead to various risk including stealing credentials from unsuspecting users.

Firmware update files may expose password hashes for system accounts, which could allow a remote attacker to recover credentials and gain unauthorized access to the device.

The device is deployed with weak and publicly known default passwords for certain hidden user levels, increasing the risk of unauthorized access. This represents a high risk to the integrity of the system.
