CVE-2019-25487: SAPIDO RB-1732 V2.0.43 Remote Command Execution via formSysCmd

SAPIDO RB-1732 V2.0.43 contains a remote command execution vulnerability that allows unauthenticated attackers to execute arbitrary system commands by submitting malicious input to the formSysCmd endpoint. Attackers can send POST requests with the sysCmd parameter containing shell commands to execute code on the device with router privileges.

Security readout for executives and security teams

Plain-English summary

CVE-2019-25487 is a critical remote command execution issue in Sapido RB-1732 router firmware 2.0.43. An unauthenticated attacker could run system commands on the device if the vulnerable management endpoint is reachable. This can compromise routing, traffic confidentiality, and device availability.

Executive priority

Treat as urgent where affected routers are exposed. Compromise could give an attacker control of network infrastructure, enabling traffic interception, outages, or further internal access.

Technical view

The sources describe unauthenticated command execution through the RB-1732 formSysCmd endpoint using attacker-controlled sysCmd input. The CVSS 3.1 score is 9.8 with network attack vector, no privileges, no user interaction, and high confidentiality, integrity, and availability impact.

Likely exposure

Exposure is limited to Sapido RB-1732 devices running firmware 2.0.43, especially where management interfaces are reachable from untrusted networks or the internet.

Exploitation context

The source bundle includes an ExploitDB reference, indicating public exploit material exists. CISA KEV status is false in the provided data, and no cited source states active exploitation.

Researcher notes

Evidence supports unauthenticated network RCE against RB-1732 V2.0.43, but the bundle does not name a vendor patch. Avoid assuming broader Sapido exposure without asset confirmation.

Mitigation direction

  • Identify Sapido RB-1732 devices and firmware versions immediately.
  • Remove internet exposure for router management interfaces.
  • Restrict administration to trusted networks or VPN access.
  • Check Sapido or trusted advisories for supported firmware guidance.
  • Replace or isolate affected devices if no supported fix is available.

Validation and detection

  • Inventory routers for Sapido RB-1732 firmware 2.0.43.
  • Confirm management endpoints are not reachable from the internet.
  • Review router logs and settings for unauthorized changes.
  • Validate firewall rules restrict administrative access.
  • Track vendor or advisory updates for remediation details.
