Moxa IKS and EDS fails to properly check array bounds which may allow an attacker to read device memory on arbitrary addresses, and may allow an attacker to retrieve sensitive data or cause device reboot.
AnalysisAI
Moxa IKS and EDS fails to properly check array bounds which may allow an attacker to read device memory on arbitrary addresses, and may allow an attacker to retrieve sensitive data or cause device. Rated critical severity (CVSS 9.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
Technical ContextAI
This vulnerability is classified as Out-of-bounds Read (CWE-125), which allows attackers to read data from memory outside the intended buffer boundaries. Moxa IKS and EDS fails to properly check array bounds which may allow an attacker to read device memory on arbitrary addresses, and may allow an attacker to retrieve sensitive data or cause device reboot. Affected products include: Moxa Iks-G6824A Firmware, Moxa Eds-405A Firmware, Moxa Eds-408A Firmware, Moxa Eds-510A Firmware.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Validate array indices and buffer lengths. Use memory-safe languages. Enable AddressSanitizer during testing.
