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.

Vendor and ecosystem advisories describing this.

  • SCA-2026-0006Vulnerabilities affecting SICK Lector85x and SICK Lector83x2026-03-06csaf · sick_psirtDE

    Two vulnerabilities affecting the SICK Lector85x and SICK Lector83x product families have been identified. Both vulnerabilities are caused by insufficient access restrictions in HTTP-based interfaces, which may allow unauthenticated access to sensitive device resources. Depending on the configuration, this could lead to unauthorized modification of device settings and security-relevant data. SICK recommends applying the defined remediations for both vulnerabilities. SICK is currently not aware of any public exploits.
