CVE-2026-36983 is a high-severity improper neutralization of special elements used in a command vulnerability in Dcs-932l Firmware from D-Link, with a CVSS 3.1 base score of 7.3 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. Affected Dcs-932l Firmware versions: 2.18.01. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 1.23% chance of exploitation within 30 days, higher than 70% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Check which version of Dcs-932l Firmware you run against the affected versions below, and install the vendor's latest release.
- Read the advisory on dlink.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
D-Link DCS-932L v2.18.01 is vulnerable to Command Injection in the function sub_42EF14 of the file /bin/alphapd. The manipulation of the argument LightSensorControl leads to command injection.

The underlying weakness: Improper Neutralization of Special Elements used in a Command
The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.
How developers prevent this class of flaw
- If at all possible, use library calls rather than external processes to recreate the desired functionality.
- If possible, ensure that all external commands called from the program are statically created.
- Run time: Run time policy enforcement may be used in an allowlist fashion to prevent use of any non-sanctioned commands.
