CVE-2022-44560 is an Intent redirection vulnerability identified in the launcher module of Huawei's HarmonyOS version 2.0. The vulnerability is classified under CWE-601, which corresponds to an open redirect issue. In this context, the launcher module improperly handles Intents, which are messaging objects used within the operating system to request actions from other components. Due to insufficient validation or sanitization of Intent parameters, an attacker can manipulate the Intent redirection process to cause the launcher module to modify its data in unintended ways. The vulnerability does not require any privileges (PR:N) or user interaction (UI:N) to be exploited and can be triggered remotely over the network (AV:N). The impact is limited to integrity (I:L) with no effect on confidentiality or availability. The CVSS v3.1 base score is 5.3, indicating a medium severity level. No known exploits have been reported in the wild, and no patches have been publicly released as of the published date (November 9, 2022). This vulnerability could be leveraged by a remote attacker to alter launcher module data, potentially affecting the normal operation or user experience of the device, but it does not directly lead to data disclosure or denial of service. The scope remains unchanged (S:U), meaning the vulnerability affects only the vulnerable component without impacting other system components.

For European organizations, the impact of CVE-2022-44560 is moderate but should not be overlooked, especially for entities relying on Huawei devices running HarmonyOS 2.0. The launcher module is a core component responsible for managing the user interface and application launching. An attacker exploiting this vulnerability could manipulate launcher data, potentially causing misdirection or unauthorized changes in the user environment. While this does not directly compromise sensitive data confidentiality or system availability, it could facilitate further social engineering attacks or malware persistence by altering launcher behavior. Organizations in sectors such as telecommunications, manufacturing, or critical infrastructure that deploy Huawei HarmonyOS devices may face operational disruptions or increased risk of targeted attacks leveraging this vulnerability as a foothold. However, the absence of known exploits and the medium severity rating suggest the immediate risk is limited. Still, the vulnerability could be a vector in multi-stage attacks or combined with other vulnerabilities to escalate impact.

Given the lack of publicly available patches, European organizations should implement specific mitigations beyond generic advice: 1) Restrict network access to HarmonyOS devices, especially from untrusted or external networks, to reduce exposure to remote exploitation. 2) Monitor device behavior and launcher module logs for unusual activity or unexpected changes in launcher data, which may indicate exploitation attempts. 3) Employ application whitelisting and restrict installation of untrusted applications that could trigger malicious Intents. 4) Use mobile device management (MDM) solutions to enforce strict security policies on HarmonyOS devices, including disabling unnecessary services and controlling Intent handling where possible. 5) Engage with Huawei support channels to obtain any available security updates or advisories and apply patches promptly once released. 6) Educate users about the risks of unsolicited links or applications that might exploit Intent redirection vulnerabilities. These targeted measures help mitigate the risk while awaiting official patches.
