ArubaOS 8.13.2.0 reads 18 bytes past packet boundaries via inflated IP Total Length. TTL=0 packets — which RFC 791 mandates must be destroyed — are processed and replied to, making the attack invisible. 27/27 crafted packets confirmed. Bugcrowd said zeroed bytes mean no vulnerability. CVE-2003-0001 and CVE-2021-3031 were accepted on the identical mechanism.
A 28-year-old vulnerability class — Smurf amplification — alive in an enterprise controller shipping in 2026. Two independent packet captures prove reflection. Bugcrowd called it expected behavior. No fix issued.
ArubaOS 8.13.2.0 exposes an unauthenticated XML parser on port 32000 that resolves external entities, enabling OOB SSRF and internal port scanning. Wire-level pcap + target sshd log confirm server-side execution. Bugcrowd closed it as theoretical. No fix issued.
TIME_WAIT and Sockstress don’t translate directly to UDP DNS, but DNS has its own state surface. Recursive-client tables, pending-query slots, TCP/853 (DoT) and TCP/443 (DoH) sockets, delegation chains, and DNSSEC validation state are all exhaustible. This post covers water torture, NXNS, TsuNAME, NRDelegation, and the operational defaults that make DNS a softer target than HTTP.
The ‘65536 port’ framing is wrong. TCP connection capacity is governed by 4-tuple uniqueness and kernel state tables, not port counts. This post breaks down TIME_WAIT exhaustion, Sockstress (window=0 + Persist Timer abuse), Slowloris-class L7 variants, and the conditions under which each is still effective today.
