CVE-2017-14948 — Certain D-Link products are affected by: Buffer Overflow

Critical CVSS 9.8

Certain D-Link products are affected by: Buffer Overflow. This affects DIR-880L 1.08B04 and DIR-895 L/R 1.13b03. The impact is: execute arbitrary code (remote). The component is: htdocs/fileaccess.cgi. The attack vector is: A crafted HTTP request handled by fileacces.cgi could allow an attacker to mount a ROP attack: if the HTTP header field CONTENT_TYPE starts with ''boundary=' followed by more than 256 characters, a buffer overflow would be triggered, potentially causing code execution.

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.
