[內容說明]
【CVE-2026-0501，CVSS：9.9】 此漏洞存在於SAP S/4HANA私有雲和本地部署(Financials – General Ledger)，由於輸入驗證不足，允許經過身分驗證的攻擊者利用特製的SQL指令進行讀取、修改和刪除後端資料庫資料。

【CVE-2026-0500，CVSS：9.6】 由於SAP Wily Introscope Enterprise Manager (WorkStation)使用易受攻擊的第三方元件，未經身分驗證的攻擊者可建立公開URL存取的惡意JNLP文件，導致受害者點擊URL時，Wily Introscope伺服器可在受害者電腦上執行作業系統命令。

【CVE-2026-0498，CVSS：9.1】 此漏洞存在於SAP S/4HANA的私有雲和本地部署，允許具有管理員權限的攻擊者透過RFC公開功能模組的漏洞，將任意ABAP程式碼/作業系統命令注入系統，從而繞過必要的授權檢查。

【CVE-2026-0491，CVSS：9.1】 SAP Landscape Transformation 允許擁有管理員權限的攻擊者利用RFC公開函數模組漏洞，將任意ABAP程式碼/作業系統命令注入系統，從而繞過必要的授權檢查。

【CVE-2026-0492，CVSS：8.8】 SAP HANA 資料庫存在權限提升漏洞，允許攻擊者擁有使用者的有效憑證，即可切換其他用戶，從而獲得管理員權限。

[Content Description]
【CVE-2026-0501, CVSS: 9.9】 This vulnerability exists in SAP S/4HANA private cloud and on-premises deployments (Financials – General Ledger). Due to insufficient input validation, it allows authenticated attackers to use specially crafted SQL commands to read, modify, and delete backend database data.

【CVE-2026-0500, CVSS: 9.6】 Because SAP Wily Introscope Enterprise Manager (WorkStation) uses vulnerable third-party components, unauthenticated attackers can create malicious JNLP files with publicly accessible URLs. When a victim clicks the URL, the Wily Introscope server can execute operating system commands on the victim's computer.

【CVE-2026-0498, CVSS: 9.1】This vulnerability exists in SAP S/4HANA's private cloud and on-premises deployments. It allows an attacker with administrator privileges to inject arbitrary ABAP code/operating system commands into the system by exploiting a vulnerability in a function module exposed in an RFC, thereby bypassing necessary authorization checks.

【CVE-2026-0491, CVSS: 9.1】This vulnerability in SAP Landscape Transformation allows an attacker with administrator privileges to exploit a vulnerability in a function module exposed in an RFC, thereby injecting arbitrary ABAP code/operating system commands into the system, thereby bypassing necessary authorization checks.

【CVE-2026-0492, CVSS: 8.8】This vulnerability in SAP HANA databases allows an attacker with valid user credentials to switch users and gain administrator privileges.
