CVE Record

CVE-2016-10665: herbivore is a packet sniffing and crafting library.

herbivore is a packet sniffing and crafting library. Built on libtins herbivore 0.0.3 and below download binary resources over HTTP, which leaves it vulnerable to MITM attacks. It may be possible to cause remote code execution (RCE) by swapping out the requested resources with an attacker controlled copy if the attacker is on the network or positioned in between the user and the remote server.

Security readout for executives and security teams

Plain-English summary

CVE-2016-10665 affects the Herbivore Node module, a packet sniffing and crafting library. Vulnerable versions downloaded binary resources over plain HTTP, allowing a network-positioned attacker to replace those resources. The source describes possible remote code execution, but provides no CVSS score and no evidence of active exploitation.

Executive priority

Treat this as a targeted supply-chain risk for teams using Herbivore, not a broad perimeter emergency. Prioritize verification in development and build environments, then remove, replace, or remediate the dependency according to vendor guidance.

Technical view

Herbivore 0.0.3 and below used insecure HTTP transport for binary resource downloads. This is mapped to CWE-311. If an attacker can intercept or modify network traffic between the user and remote server, they may substitute attacker-controlled resources. The affected product metadata says “All versions,” while the description says “0.0.3 and below,” so version scope is inconsistent.

Likely exposure

Exposure is most likely in developer machines, CI systems, or applications that install or use the Herbivore Node module. Systems that never install Herbivore, or only install packages through controlled, trusted artifact sources, are less likely to be exposed.

Exploitation context

The cited material supports a man-in-the-middle scenario, not unauthenticated internet-wide exploitation. The attacker must be on the network path or otherwise able to alter the HTTP resource download. KEV status is false, and the bundle provides no public evidence of active exploitation.

Researcher notes

The core issue is insecure transport for binary resource acquisition. The main evidentiary gaps are missing CVSS data, inconsistent affected-version wording, and no explicit exploitation evidence. Do not assume active exploitation or a universal fixed version without checking the advisory and commit details.

Mitigation direction

  • Inventory projects and build systems for the Herbivore Node module.
  • Review the linked commit and Node Security advisory for vendor remediation guidance.
  • Avoid installing vulnerable dependencies over untrusted or interceptable networks.
  • Use trusted package mirrors or internal artifact repositories where feasible.
  • Remove or replace Herbivore if no maintained fixed version is available.

Validation and detection

  • Check dependency manifests and lockfiles for Herbivore usage.
  • Identify whether any listed Herbivore version matches 0.0.3 or below.
  • Review CI and workstation install history for Herbivore binary downloads.
  • Confirm whether build environments use trusted artifact sources.
  • Document any version-scope uncertainty from the conflicting affected-version statements.
