Title:Cisco IOS XE Software 安全漏洞 (CVE-2023-20198)
Description:Cisco is providing an update for the ongoing investigation into observed exploitation of the web UI feature in Cisco IOS XE Software. We are updating the list of fixed releases and adding the Software Checker. Our investigation has determined that the actors exploited two previously unknown issues. The attacker first exploited CVE-2023-20198 to gain initial access and issued a privilege 15 command to create a local user and password combination. This allowed the user to log in with normal user access. The attacker then exploited another component of the web UI feature, leveraging the new local user to elevate privilege to root and write the implant to the file system. Cisco has assigned CVE-2023-20273 to this issue. CVE-2023-20198 has been assigned a CVSS Score of 10.0. CVE-2023-20273 has been assigned a CVSS Score of 7.2. Both of these CVEs are being tracked by CSCwh87343.

## Description.
1vere$k POC on the CVE-2023-20198 based on the [Blog](https://blog.talosintelligence.com/active-exploitation-of-cisco-ios-xe-software/).  Also including a check on hexademical response according to the original [Cisco article](https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-iosxe-webui-privesc-j22SaA4z).

The script works in the two modes:  
 * `check` mode which is just makes a connection for the particular URL and checks a response code. If it is 200OK and in the same time response is less then 32 symbols it is a ***possibility*** your device is compromised.
 * `exploit` mode. For the particular one you should define username, password, compromised configuration.
 * added http/https schemas support as recommended in the Cisco article.
 * for getting help just use `-h` flag.
