CVE-2026-85384
HighCVSS 8.5Exploitation Probability (EPSS)
Low risk11th percentile - higher than 11% of all known CVEs
Summary
A stack-based buffer overflow vulnerability exists in the httpd component of RE210 AC750 due to improper bounds checking in the splitString function when processing an uploaded configuration file. An authenticated attacker on the local network can upload a crafted configuration file to trigger the overflow, leading to remote code execution. Successful exploitation may allow unauthorized access to sensitive information, modification of device configuration and network behavior, or disruption of device availability.
Risk Assessment
The risk includes potential device takeover, which could lead to data confidentiality breaches, network configuration changes, or denial of service.
Recommendation
It is recommended to restrict access to the administrative interface and update the firmware if a patch is available. Also monitor logs for suspicious activity.
