DescriptionCVE.org

A vulnerability was determined in taoofagi easegen-admin up to 8f87936ac774065b92fb20aab55b274a6ea76433. This issue affects the function downloadFile of the file - yudao-module-digitalcourse/yudao-module-digitalcourse-biz/src/main/java/cn/iocoder/yudao/module/digitalcourse/util/PPTUtil.java of the component PPT File Handler. This manipulation of the argument url causes server-side request forgery. It is possible to initiate the attack remotely. The exploit has been publicly disclosed and may be utilized. This product is using a rolling release to provide continious delivery. Therefore, no version details for affected nor updated releases are available. The vendor was contacted early about this disclosure but did not respond in any way.

AnalysisAI

The PPT File Handler in taoofagi easegen-admin contains a server-side request forgery vulnerability in the downloadFile function that allows authenticated remote attackers to manipulate file URLs and access arbitrary network resources. Public exploit code exists for this vulnerability, and the vendor has not provided patches or updates despite notification. The flaw affects Java-based deployments using the affected rolling release version.

Technical ContextAI

Server-Side Request Forgery allows an attacker to induce the server to make HTTP requests to arbitrary destinations, including internal services. This vulnerability is classified as Server-Side Request Forgery (SSRF) (CWE-918).

RemediationAI

Validate and whitelist allowed URLs and IP ranges. Block requests to internal/private IP ranges. Use network segmentation to limit server-side request scope.
