Ir915l-fq39-s Firmware: Improper Neutralization of Special Elements used in a Command
CVE-2026-38716 is a critical-severity improper neutralization of special elements used in a command vulnerability in Ir915l-fq39-s Firmware from Inhandnetworks, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 1.0.0.r20044 as the first without the flaw, so updating Ir915l-fq39-s Firmware to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 2.31% chance of exploitation within 30 days, higher than 84% of scored CVEs.
Critical severity: a successful attack would have severe impact.
What to do
- Update Ir915l-fq39-s Firmware to 1.0.0.r20044 or a later version.
- Update Ir912l-fq58 Firmware to 1.0.0.r20044 or a later version.
- Read the advisory on inhand.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
InHand Networks IR912 V1.0.0.r20042 and IR915 V1.0.0.r20042 (including earlier versions) were discovered to contain a command injection vulnerability in the Python application export function. This vulnerability allows remote attackers to execute arbitrary commands as root via a crafted input.

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.
