CVE-2016-6376 — Cisco Wireless Lan Controller security vulnerability
Medium
CVSS 6.5
The Adaptive Wireless Intrusion Prevention System (wIPS) feature on Cisco Wireless LAN Controller (WLC) devices before 8.0.140.0, 8.1.x and 8.2.x before 8.2.121.0, and 8.3.x before 8.3.102.0 allows remote attackers to cause a denial of service (device restart) via a malformed wIPS packet, aka Bug ID CSCuz40263.

Matched remediation archetype
Resource exhaustion and denial of service
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Identify attacker-influenced work factors including input size, nesting, compression, fan-out, regex cost, allocation, recursion, retries, and connection lifetime.
- Map per-request and shared CPU, memory, disk, descriptor, thread, queue, and downstream-service limits.
- Determine whether authentication, tenancy, quotas, and rate controls apply before expensive processing begins.
Remediate safely
- Bound input size, nesting, expansion, work, concurrency, queue depth, retries, and execution time before resource-intensive processing.
- Release resources on every success, error, cancellation, and timeout path and use backpressure instead of unbounded buffering.
- Update affected components and add small deterministic tests that assert resource ceilings rather than exhausting a host.
