CVE-2022-22333 — Ibm Sterling External Authentication Server security vulnerability

Medium CVSS 6.5

IBM Sterling Secure Proxy 6.0.3.0, 6.0.2.0, and 3.4.3.2 and IBM Sterling External Authentication Server are vulnerable a buffer overflow, due to the Jetty based GUI in the Secure Zone not properly validating the sizes of the form content and/or HTTP headers submitted. A local attacker positioned inside the Secure Zone could submit a specially crafted HTTP request to disrupt service. IBM X-Force ID: 219133.

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.
