EIP tracks 2 public exploits for CVE-2019-1937. PoCs published by Fatih Sencer, including Metasploit module exploits/linux/http/cisco_ucs_rce.

AI-analyzed exploit summary This exploit bypasses authentication in Cisco IMC Supervisor by sending a crafted GET request to the `/app/ui/ClientServlet?apiName=GetUserInfo` endpoint with specific headers, allowing an attacker to retrieve user session information without valid credentials.

Description

A vulnerability in the web-based management interface of Cisco Integrated Management Controller (IMC) Supervisor, Cisco UCS Director, and Cisco UCS Director Express for Big Data could allow an unauthenticated, remote attacker to acquire a valid session token with administrator privileges, bypassing user authentication. The vulnerability is due to insufficient request header validation during the authentication process. An attacker could exploit this vulnerability by sending a series of malicious requests to an affected device. An exploit could allow the attacker to use the acquired session token to gain full administrator access to the affected device.
