MITRE Techniques :
- Stored Cross-Site Scripting (XSS) (T1059.007) – Exploits a vulnerability allowing attackers to inject malicious scripts into content that is then served to users.
- SQL Injection (SQLi) (T1190) – Involves inserting malicious SQL queries into input fields, allowing attackers to manipulate backend databases.
- Server-Side Request Forgery (SSRF) (T9420) – Allows attackers to send crafted requests from the server to internal or external domains, potentially exposing sensitive information or systems.
Indicator of Compromise :
- [CVE Number] CVE-2025-27915
- [CVE Number] CVE-2025-25064
- [CVE Number] CVE-2025-25065
