CVE-2023-20205 : What You Need to Know

This CVE involves multiple vulnerabilities found in the web-based management interface of Cisco Prime Infrastructure and Cisco Evolved Programmable Network Manager (EPNM). These vulnerabilities could potentially allow an authenticated, remote attacker to conduct a stored cross-site scripting (XSS) attack against a user of the interface on an affected device.

Understanding CVE-2023-20205

The vulnerabilities stem from inadequate validation of user-supplied input, enabling an attacker to execute arbitrary script code in the context of the affected interface or access sensitive browser-based information.

What is CVE-2023-20205?

CVE-2023-20205 is a security vulnerability identified in the web-based management interface of Cisco Prime Infrastructure and Cisco EPNM. It allows a remote attacker with valid credentials to perform a stored cross-site scripting (XSS) attack on a user of the affected interface.

The Impact of CVE-2023-20205

The exploitation of these vulnerabilities could lead to unauthorized execution of script code within the interface, potentially compromising sensitive information accessed through the affected device's browser.

Technical Details of CVE-2023-20205

The vulnerability description includes insufficient validation of user-supplied input, specifically in the web-based management interface of Cisco Prime Infrastructure and Cisco EPNM.

Vulnerability Description
