[內容說明]
研究人員發現Cisco ISE與ISE-PIC存在多項高風險安全漏洞(CVE-2026-20130、CVE-2026-20192、CVE-2026-20307、CVE-2026-76423及CVE-2026-76460)，類型包含程式碼注入(Code Injection)、不當存取控制(Improper Access Control)、不安全之反序列化(Insecure Deserialization)及身分鑑別繞過(Authentication Bypass)。其中CVE-2026-76460已遭駭客濫用，請儘速確認並進行修補。

【CVE-2026-20130】 未經身分鑑別之遠端攻擊者可藉由在傳遞至下游元件之輸出中，植入未經妥善處理之特殊元素，於受影響裝置執行任意程式碼。

【CVE-2026-20192】 未經身分鑑別之遠端攻擊者可繞過身分鑑別與授權限制，進而未授權存取受影響裝置。

【CVE-2026-20307】 已通過身分鑑別之遠端攻擊者可藉由向網頁管理介面傳送特製之Java序列化物件，於底層作業系統執行任意程式碼，並將權限提升至root。

【CVE-2026-76423】 未經身分鑑別之遠端攻擊者可藉由向對外開放之REST API連接埠傳送特製HTTP請求，以管理者權限讀取及變更ISE組態與身分資料。

【CVE-2026-76460】 未經身分鑑別之遠端攻擊者可藉由向存在缺陷之API端點傳送特製請求，繞過網頁管理介面之身分鑑別，進而未授權存取受影響裝置。

[影響平台]
Cisco ISE與ISE-PIC 3.1至3.5版本
Cisco ISE與ISE-PIC 3.0(含)以前版本(已終止軟體維護)

[Content Description]
Researchers have discovered multiple high-risk security vulnerabilities in Cisco ISE and ISE-PIC (CVE-2026-20130, CVE-2026-20192, CVE-2026-20307, CVE-2026-76423 and CVE-2026-76460), including Code Injection, Improper Access Control, Insecure Deserialization and Authentication Bypass. Among them, CVE-2026-76460 has been exploited by attackers. Please confirm and apply patches as soon as possible.

【CVE-2026-20130】 An unauthenticated remote attacker may execute arbitrary code on an affected device by injecting improperly handled special elements into output passed to downstream components.

【CVE-2026-20192】 An unauthenticated remote attacker may bypass authentication and authorization restrictions, thereby gaining unauthorized access to affected devices.

【CVE-2026-20307】 An authenticated remote attacker may send crafted Java serialized objects to the web management interface to execute arbitrary code on the underlying operating system and escalate privileges to root.

【CVE-2026-76423】 An unauthenticated remote attacker may send crafted HTTP requests to the externally exposed REST API port to read and modify ISE configurations and identity data with administrator privileges.

【CVE-2026-76460】 An unauthenticated remote attacker may send crafted requests to a vulnerable API endpoint to bypass authentication of the web management interface, thereby gaining unauthorized access to affected devices.

[Impacted Platforms]
Cisco ISE and ISE-PIC versions 3.1 to 3.5
Cisco ISE and ISE-PIC versions 3.0 (inclusive) and earlier versions (software maintenance has ended)
