Technical Summary
CVE-2026-10829 is a stack-based buffer overflow vulnerability affecting Moxa NPort W2150A-W4/W2250A-W4 Series version 1.5 and earlier. It arises from improper input validation of user-supplied data in the "Server location" parameter of the device's web interface. An attacker can send crafted input to trigger memory corruption, which may allow remote code execution with root privileges. The vulnerability has a CVSS 4.0 score of 8.6, indicating high severity. No vendor advisory or patch information is currently available, and no known exploits in the wild have been reported.
Potential Impact
Successful exploitation could allow an attacker to execute arbitrary code remotely on the affected device with root-level privileges, potentially leading to full system compromise. This could impact device availability, confidentiality, and integrity.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to the device's web interface to trusted networks and users only to reduce exposure.
