CVE-2022-41576: Weaknesses Introduced During Design in Huawei HarmonyOS
The rphone module has a script that can be maliciously modified.Successful exploitation of this vulnerability may cause irreversible programs to be implanted on user devices.
AI Analysis
Technical Summary
CVE-2022-41576 is a high-severity vulnerability identified in Huawei's HarmonyOS version 2.0, specifically within the rphone module. The vulnerability stems from design weaknesses that allow a script within this module to be maliciously modified. This vulnerability is classified under CWE-94, which relates to improper control of code generation, commonly known as code injection or unsafe script modification. Successful exploitation requires local access with low privileges (PR:L) and does not require user interaction (UI:N). The attack vector is local (AV:L), meaning the attacker must have some level of access to the device, such as physical access or through another compromised local account. Exploiting this vulnerability can lead to the implantation of irreversible programs on user devices, implying that attackers can execute arbitrary code with high impact on confidentiality, integrity, and availability. The CVSS v3.1 score is 7.8, indicating a high severity level. The vulnerability affects the rphone module's script, which if altered maliciously, can compromise the device's security posture. Although no known exploits are currently reported in the wild, the potential for severe damage exists due to the ability to implant persistent malicious programs. The lack of available patches at the time of reporting increases the risk for affected users. The vulnerability's scope is limited to HarmonyOS 2.0 devices, which are primarily used on Huawei smartphones and IoT devices. Given the local attack vector and the need for low privileges, the threat is significant in scenarios where devices might be physically accessed or where local accounts can be compromised through other means.
Potential Impact
For European organizations, the impact of CVE-2022-41576 could be substantial, particularly for those using Huawei HarmonyOS devices within their operational environments. The ability to implant irreversible malicious programs threatens the confidentiality of sensitive data, integrity of system operations, and availability of critical services. Organizations relying on Huawei devices for communication or IoT infrastructure could face persistent malware infections that are difficult to detect and remove. This could lead to data breaches, espionage, or disruption of business processes. Additionally, the high severity and potential for persistent compromise increase the risk of long-term operational impact. The local attack vector suggests that insider threats or attackers who gain physical access to devices pose the greatest risk. For sectors such as government, telecommunications, and critical infrastructure in Europe, where Huawei devices may be deployed, this vulnerability could be exploited to undermine security and trust. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, especially as attackers may develop exploits over time.
Mitigation Recommendations
European organizations should implement specific mitigation strategies beyond generic advice: 1) Inventory and Audit: Conduct a thorough inventory of all Huawei HarmonyOS 2.0 devices in use, including smartphones and IoT devices, to identify potentially vulnerable endpoints. 2) Access Controls: Strengthen physical security controls to prevent unauthorized local access to devices. This includes secure storage, device locking policies, and monitoring of device usage. 3) Privilege Management: Enforce strict privilege separation and limit local user privileges to reduce the risk of exploitation by low-privileged users. 4) Monitoring and Detection: Deploy endpoint detection and response (EDR) solutions capable of monitoring script modifications and unusual behaviors in the rphone module or related processes. 5) Patch Management: Engage with Huawei for updates or patches addressing this vulnerability and prioritize their deployment once available. 6) Incident Response Preparedness: Develop and test incident response plans specifically for device compromise scenarios involving persistent malware. 7) User Awareness: Educate users about the risks of physical device access and encourage reporting of lost or stolen devices promptly. 8) Network Segmentation: Isolate vulnerable devices within network segments to limit lateral movement in case of compromise. These measures collectively reduce the attack surface and improve detection and response capabilities against exploitation attempts.
