CVE-2022-42488
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedOpenHarmony-v3.1.2 and prior versions have a Missing permission validation vulnerability in param service of startup subsystem. An malicious application installed on the device could elevate its privileges to the root user, disable security features, or cause DoS by disabling particular services.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceOpenHarmony v3.1.2 and prior versions contain a missing permission validation vulnerability in the param service of the startup subsystem. This allows any malicious application installed on the device to manipulate system parameters without proper authorization checks, enabling privilege escalation to root, disabling security features, or causing denial of service by stopping critical services.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the OpenHarmony versionCheck the system or build configuration file for the OpenHarmony version number (typically found in build configuration, system properties, or the version manifest file)Affected if The installed version is 3.1.0, 3.1.1, or any version >= 3.1 but less than 3.1.2
-
Verify the param service is presentInspect the startup subsystem components to confirm the param service module is included in the buildAffected if The param service module exists in the startup subsystem and is included in the device firmware
-
Confirm application installation is permittedReview device settings or policy configurations to determine if installation of applications from untrusted or third-party sources is allowedAffected if The device permits installation of applications from sources other than trusted, vetted app stores
-
Check for unauthorized system parameter modificationsReview system parameter values (typically stored in /param or similar system directories) for unexpected or malicious changes, particularly parameters related to security settings, service configurations, or root access controlsAffected if System parameters have been modified to values that enable root privileges, disable security features, or alter critical service configurations
-
Monitor for suspicious application behaviorAudit application permissions and behavior logs for any installed applications that are accessing or modifying system parameters without appropriate privilegesAffected if Any application has manipulated system parameters despite lacking authorized permissions
A device is affected if it runs OpenHarmony version 3.1.0 or 3.1.1 (any version >= 3.1 but below 3.1.2) and has the param service enabled, particularly if the device allows installation of third-party applications.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped3.1.2
Apply any available vendor patches for OpenHarmony. Until patched, restrict application installations to trusted sources and monitor for suspicious application behavior. The vulnerability requires a code-level fix to add proper permission validation in the param service.
OpenHarmony 3.1.2 or later
- Upgrade OpenHarmony from any version >= 3.1 and < 3.1.2 to version 3.1.2 or later
- After upgrade, verify the param service in the startup subsystem is functioning correctly
- Confirm the permission validation is now enforced in the param service
