Cardo Systems Scala Rider Q3 Cardo-Updater api privileges management

Vulnerability

The Cardo-Updater application, installed as part of the Cardo Systems Scala Rider Q3 firmware update software (version 1.7 for OSX, and equivalent Windows version), runs as a LaunchAgent with root privileges and listens on TCP port 8080 on all network interfaces. The service exposes a vulnerable endpoint at /cardo/api that allows unauthenticated remote code execution. No authentication or user interaction is required to reach this endpoint. [1]

Exploitation

An attacker on the same network (or remotely if the port is exposed) can send a crafted HTTP request to the Cardo-Updater's web interface on port 8080 targeting the /cardo/api path. No prior authentication or credentials are needed. The service runs with root privileges, so any command injected via the API will be executed as root. [1]

Impact

Successful exploitation allows an unauthenticated attacker to execute arbitrary commands with root privileges on the affected machine. This results in complete compromise of the system: full information disclosure, modification or deletion of files, installation of malware, and persistent unauthorized access. [1]

Mitigation

The official recommendation from the researcher and vendor is to either firewall the service (block TCP port 8080) or disable the Cardo-Updater service entirely. No patched version has been released for this vulnerability, and the product may be end-of-life. The CVE is not listed on the CISA Known Exploited Vulnerabilities (KEV) catalog. [1]
