CVE-2023-42470
Published: 11 September 2023
Summary
CVE-2023-42470 is a critical-severity Code Injection (CWE-94) vulnerability in Imoulife Life. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 5.6% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
The Imou Life application (package com.mm.android.smartlifeiot) through version 6.8.0 for Android is affected by a remote code execution vulnerability. The flaw resides in the exported MainActivity component (com.mm.android.easy4ip.MainActivity), where JavaScript execution is enabled inside a WebView that also performs direct loading of web content, combined with improper handling of incoming intents.
An unauthenticated attacker can deliver a crafted intent to the exported activity and achieve arbitrary code execution on the device. Successful exploitation grants the attacker the ability to run code in the context of the application with no user interaction required, corresponding to the CVSS 9.8 rating and CWE-94 classification.
Public proof-of-concept material, including an APK and detailed reproduction steps, has been published on GitHub. The current EPSS score of 0.1358 (peak 0.1535) indicates moderate and relatively stable exploitation interest since disclosure. No official vendor advisory or patch information is referenced in the available sources.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.
Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.
Validates inputs used in dynamic code generation to block injected directives.
Directly prevents execution of attacker-supplied code written into data memory regions.
