Published: 04 March 2025
Summary
CVE-2025-24309 is a low-severity Out-of-bounds Write (CWE-787) vulnerability in Openatom Openharmony. Its CVSS base score is 3.8 (Low).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked at the 28.8th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-16 (Memory Protection) and SI-2 (Flaw Remediation).
Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Implements memory protection mechanisms such as ASLR and DEP to directly prevent exploitation of out-of-bounds write vulnerabilities for arbitrary code execution.
Ensures timely identification, reporting, and patching of the specific OpenHarmony out-of-bounds write flaw as detailed in the security advisory.
Provides process isolation for pre-installed applications to contain arbitrary code execution by local low-privilege attackers within restricted scenarios.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Out-of-bounds write enabling local low-privilege arbitrary code execution in pre-installed apps directly facilitates exploitation for privilege escalation.
NVD Description
in OpenHarmony v5.0.2 and prior versions allow a local attacker arbitrary code execution in pre-installed apps through out-of-bounds write. This vulnerability can be exploited only in restricted scenarios.
Deeper analysisAI
CVE-2025-24309 is an out-of-bounds write vulnerability (CWE-787) present in OpenHarmony versions v5.0.2 and prior. Published on 2025-03-04, it enables a local attacker to achieve arbitrary code execution within pre-installed applications.
The vulnerability can be exploited by a local attacker who has low privileges (PR:L), requiring low attack complexity (AC:L) and no user interaction (UI:N). Exploitation results in arbitrary code execution in pre-installed apps, though it is limited to restricted scenarios. The CVSS v3.1 base score is 3.8 (AV:L/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N), reflecting low severity with changed scope and limited confidentiality impact.
