CVE-2018-25219 — Passfab Excel Password Recovery security vulnerability

High CVSS 8.6

PassFab Excel Password Recovery 8.3.1 contains a structured exception handling buffer overflow vulnerability that allows local attackers to execute arbitrary code by supplying a malicious payload in the registration code field. Attackers can craft a buffer overflow payload with a pop-pop-ret gadget and shellcode that triggers code execution when pasted into the Licensed E-mail and Registration Code field during the registration process.

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.
