Description
A vulnerability was identified in taoofagi easegen-admin up to 8f87936ac774065b92fb20aab55b274a6ea76433. Impacted is the function recognizeMarkdown of the file yudao-module-digitalcourse/yudao-module-digitalcourse-biz/src/main/java/cn/iocoder/yudao/module/digitalcourse/util/Pdf2MdUtil.java. Such manipulation of the argument fileUrl leads to path traversal. It is possible to launch the attack remotely. The exploit is publicly available and might be used. This product takes the approach of rolling releases to provide continious delivery. Therefore, version details for affected and updated releases are not available. The vendor was contacted early about this disclosure but did not respond in any way.
Public exploit
An exploit or proof of concept is public: anyone can try it against an unpatched system. A reference of the record is tagged as an exploit. CISA's SSVC rates its exploitation: a proof of concept is public.
