CVE-2026-2331 (GCVE-0-2026-2331)

Vulnerability from nvd – Published: 2026-03-06 07:56 – Updated: 2026-03-09 21:04
VLAI?
Title
CVE-2026-2331
Summary
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.

CVE-2026-2330 (GCVE-0-2026-2330)

Vulnerability from nvd – Published: 2026-03-06 07:54 – Updated: 2026-03-09 21:04
VLAI?
Title
CVE-2026-2330
Summary
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.

CVE-2026-2331 (GCVE-0-2026-2331)

Vulnerability from cvelistv5 – Published: 2026-03-06 07:56 – Updated: 2026-03-09 21:04
VLAI?
Title
CVE-2026-2331
Summary
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.

Title
CVE-2026-2330
Summary
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.
