Published: 04 March 2025
Description
Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.
Security Summary
CVE-2025-22835 is an out-of-bounds write vulnerability (CWE-787) in OpenHarmony versions v5.0.2 and prior. It enables a local attacker to achieve arbitrary code execution within pre-installed applications.
A local attacker with low privileges can exploit this vulnerability with low attack complexity and no user interaction required (CVSS:3.1/AV:L/AC:L/PR:L/UI:N). Successful exploitation changes scope (S:C), resulting in low confidentiality impact (C:L) but no integrity or availability impact (I:N/A:N), for an overall base score of 3.8. Exploitation is restricted to specific scenarios.

Why these techniques?
The OOB write vulnerability directly enables local low-privileged attackers to achieve arbitrary code execution in pre-installed applications (with scope change), mapping to exploitation for privilege escalation as it provides access beyond the attacker's initial context.
