CVE intelligence and bounded remediation
CVE-2025-56311 — In Shenzhen C-Data Technology Co
In Shenzhen C-Data Technology Co. FD602GW-DX-R410 (firmware v2.2.14), the web management interface contains an authenticated CSRF vulnerability on the reboot endpoint (/boaform/admin/formReboot). An attacker can craft a malicious webpage that, when visited by an authenticated administrator, causes the router to reboot without explicit user consent. This lack of CSRF protection on a sensitive administrative function can lead to denial of service by disrupting network availability.

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.
