Resource Depletion in Intel Puma 5/6/7 Firmware

IdentifiersCVE-2017-5693CWE-400· Uncontrolled Resource Consumption

A vulnerability in the firmware of Intel Puma 5, 6, and 7 Series cable modem chipsets allows a remote network attacker to cause resource depletion or timeouts by sending crafted network traffic. This can lead to a denial of service condition on affected devices.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows a remote attacker to cause denial of service on affected cable modems, potentially disrupting internet connectivity for end users. The attack does not require authentication and can be performed over the network.

Mitigation

If you can’t patch tonight, do this now.

If firmware updates are not available, network-level mitigations such as filtering or rate-limiting suspicious or malformed traffic may reduce the risk of exploitation.

Remediation

Patch, then assume compromise.

Update the firmware of affected Intel Puma 5, 6, and 7 Series devices to a version provided by the device manufacturer that addresses this vulnerability.

Puma6FailMaturityPoCVerified exploit

This repository is a proof-of-concept (PoC) exploit for CVE-2017-5693, a denial-of-service vulnerability in the Intel Puma 6 chipset, commonly found in devices such as the Virgin Media Super Hub 3 modem. The main code is in 'src/main.rs', written in Rust, and implements a configurable UDP flooder. The user specifies the target IP address (IPv4 or IPv6), payload size, bandwidth (in Mbps), number of destination ports, and optionally the duration of the attack. The tool then sends high-rate UDP packets to the target, exploiting the chipset's vulnerability to cause significant latency and packet loss. The repository contains standard Rust project files and documentation, with the exploit logic entirely in 'src/main.rs'. No hardcoded IPs or domains are present; the target is supplied at runtime. The exploit is operational as a PoC and demonstrates the impact of the vulnerability but does not provide weaponized or framework-level automation.
