Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Cisco ISE suffers from insufficient file validation. π **Consequences**: Attackers can upload and execute **arbitrary files**, leading to full system compromise.
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: **CWE-269** (Improper Privilege Management) & **CWE-20** (Improper Input Validation). The flaw lies in inadequate verification of uploaded files.
Q3Who is affected? (Versions/Components)
π’ **Affected**: **Cisco Identity Services Engine (ISE)** and **Cisco ISE-PIC**. These are NAC solutions managing zero-trust access.
Q4What can hackers do? (Privileges/Data)
π **Impact**: **Full Control**. CVSS Score is **Critical (9.8)**. Hackers gain High Confidentiality, Integrity, and Availability impact. They can execute commands as root/system.
Q5Is exploitation threshold high? (Auth/Config)
β‘ **Threshold**: **LOW**. Exploitation requires **No Authentication (PR:N)**, **Low Complexity (AC:L)**, and **No User Interaction (UI:N)**. It's remote and easy.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Exploit Status**: **YES**. A public **PoC** exists on GitHub (`skadevare/CiscoISE-CVE-2025-20282-POC`). It abuses the `/admin/files-upload/` endpoint.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for the unauthenticated endpoint `/admin/files-upload/`. Check if the ISE version is vulnerable. Look for unauthorized file upload capabilities.
π§ **No Patch?**: **Block** external access to `/admin/files-upload/` via firewall/WAF. Restrict network access to ISE management interfaces strictly.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: **CRITICAL**. CVSS 9.8 + Public PoC + No Auth required. **Patch NOW**. This is a 'perfect 10' scenario for attackers.
