CVE-2024-24959 — Automationdirect P3-550E Firmware security vulnerability

High CVSS 8.2

Several out-of-bounds write vulnerabilities exist in the Programming Software Connection FileSystem API functionality of AutomationDirect P3-550E 1.2.10.9. Specially crafted network packets can lead to heap-based memory corruption. An attacker can send malicious packets to trigger these vulnerabilities.This CVE tracks the arbitrary null-byte write vulnerability located in firmware 1.2.10.9 of the P3-550E at offset `0xb6c18`.

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.
