CVE-2018-10695 — An issue was discovered on Moxa AWK-3121 1.14 devices

High CVSS 8.8

An issue was discovered on Moxa AWK-3121 1.14 devices. It provides alert functionality so that an administrator can send emails to his/her account when there are changes to the device's network. However, the same functionality allows an attacker to execute commands on the device. The POST parameters "to1,to2,to3,to4" are all susceptible to buffer overflow. By crafting a packet that contains a string of 678 characters, it is possible for an attacker to execute the attack.

Matched remediation archetype

Buffer bounds, memory safety, and memory corruption

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Identify affected native-code versions, build flags, architectures, parsers, codecs, drivers, and input paths in all shipped artifacts.
  • Determine whether untrusted data reaches the affected routine and the process privilege, sandbox, and network exposure.
  • Confirm statically linked, vendored, firmware, and platform-provided copies, not only package-manager records.

Remediate safely

  • Apply the maintained upstream correction or replace the affected component, then rebuild every dependent artifact from clean inputs.
  • Adopt bounds-checked interfaces, validated sizes and integer conversions, clear ownership, and memory-safe components where practical.
  • Enable supported compiler and runtime hardening and add sanitized tests and fuzz regression seeds derived from non-weaponized fixtures.
