CVE-2019-7231 — The ABB IDAL FTP server is vulnerable to a buffer overflow when a long string is sent by an authenticated attacker

Medium CVSS 5.7

The ABB IDAL FTP server is vulnerable to a buffer overflow when a long string is sent by an authenticated attacker. This overflow is handled, but terminates the process. An authenticated attacker can send a FTP command string of 472 bytes or more to overflow a buffer, causing an exception that terminates the server.

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.
