Deeper analysis
CSZCMS version 1.3.0 contains a server-side request forgery vulnerability at the path /admin/filemanager/connector/. The flaw is tracked as CVE-2022-28997 with a CVSS 3.1 score of 7.5 and is categorized under CWE-918. It permits an attacker to supply crafted requests that the application then issues on the server’s behalf, which can be chained with local file inclusion to read arbitrary files and thereby expose sensitive data.
Remote attackers require no authentication or user interaction to reach the affected endpoint. Successful exploitation yields read access to files on the server, enabling disclosure of configuration data, credentials, or other sensitive information stored on the host.
The supplied references consist of proof-of-concept images and a PacketStorm entry describing an SSRF-to-LFI chain that can lead to remote code execution; none of the references contain vendor advisories or patch details.
EPSS for the CVE remained low after the 2022 disclosure but rose sharply to a peak of 0.1989 on 2025-01-22 before receding to the current value of 0.0053, indicating that exploitation interest emerged well after public release.
