AI Analysis

Impact

An OS command injection flaw exists in Seiko Solutions’ SkyBridge MB‑A100 and MB‑A110 devices caused by improper neutralization of special characters in operating‑system commands, and it corresponds to CWE‑78. When exploited, an attacker who can authenticate with administrative privileges can execute arbitrary commands on the device’s underlying OS, potentially compromising device integrity, confidentiality, and availability.

Affected Systems

The vulnerability affects Seiko Solutions Inc.’s SkyBridge MB‑A100 and MB‑A110 devices. All current releases are potentially vulnerable until a vendor patch is applied, as no specific firmware or software version ranges are provided in the CNA data.

Risk and Exploitability

The CVSS score of 8.6 indicates a high severity risk. The EPSS score of 1% reflects a low but non‑negligible likelihood of exploitation, and the issue is not listed in CISA’s KEV catalog. The attack vector is limited to users or systems that can log in as an administrator. Once authenticated, the attacker can inject and run any OS command, leading to full control over the device.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Apply the latest firmware or security patch released by Seiko Solutions that addresses the command‑injection flaw (CWE‑78).
  • If a patch is not yet available, restrict administrative access to trusted hosts and enforce strong authentication mechanisms such as MFA to reduce the likelihood of credential compromise.
  • Disable the option to execute arbitrary OS commands from the web interface if possible, and consider placing the device behind a firewall or network segmentation to isolate it from critical infrastructure.
