This vulnerability in Mavis HTTPS to HTTP Redirection allows an attacker to perform CSRF attacks that result in Stored XSS. The affected versions are from an unspecified initial version through 1.4.3. The CVSS 3.1 score is 7.1, indicating high severity, with attack vector network, low attack complexity, no privileges required, user interaction required, scope changed, and impacts on confidentiality, integrity, and availability at low to high levels.

Successful exploitation could allow an attacker to execute stored malicious scripts in the context of the vulnerable application, potentially leading to unauthorized actions performed on behalf of authenticated users, partial data disclosure, data modification, and service disruption. The scope change indicates that the vulnerability affects resources beyond the initially vulnerable component.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
