Cam v2: Improper Neutralization of Special Elements used in a Command

CVE-2023-6321 is a high-severity improper neutralization of special elements used in a command vulnerability in Cam v2 from Owlet, with a CVSS 3.1 base score of 8.8 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. The record lists version 4.2.10 as the first without the flaw, so updating Cam v2 to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 2.75% chance of exploitation within 30 days, higher than 86% of scored CVEs.

Official description

A command injection vulnerability exists in the IOCTL that manages OTA updates. A specially crafted command can lead to command execution as the root user. An attacker can make authenticated requests to trigger this vulnerability.

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.
