Router: Improper Neutralization of Special Elements in Output Used by a Downstream Component

Published Updated By the CyberSecBulletin desk

CVE-2026-75985 is a high-severity improper neutralization of special elements in output used by a downstream component vulnerability in Router from TRENDnet, with a CVSS 3.1 base score of 7.4 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. Affected Router versions: 1.1.02b01. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 1.82% chance of exploitation within 30 days, higher than 79% of scored CVEs.

Official description

A flaw has been found in TRENDnet Router 1.1.02b01. The affected element is an unknown function of the file /cgi-bin/ping.cgi. This manipulation of the argument wan_type causes command injection. The attack may be initiated remotely. The exploit has been published and may be used.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: Improper Neutralization of Special Elements in Output Used by a Downstream Component

The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.

How developers prevent this class of flaw

  • Programming languages and supporting technologies might be chosen which are not subject to these issues.
  • Utilize an appropriate mix of allowlist and denylist parsing to filter control-plane syntax from all input.
