The cgi-bin/webfile_mgr.cgi file allows arbitrary file write by abusing symlinks. Specifically, this occurs by uploading a tar archive that contains a symbolic link, then uploading another archive that writes a file to the link using the \"cgi_untar\" command. Other commands might also be susceptible. Code can be executed because the \"name\" parameter passed to the cgi_unzip command is not sanitized." } ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "n/a" } ] } ] }, "references": { "reference_data": [ { "refsource": "CONFIRM", "name": "https://community.wd.com/t/new-release-my-cloud-firmware-versions-2-31-183-05-20-2019/237717", "url": "https://community.wd.com/t/new-release-my-cloud-firmware-versions-2-31-183-05-20-2019/237717" }, { "refsource": "MISC", "name": "https://bnbdr.github.io/posts/wd/", "url": "https://bnbdr.github.io/posts/wd/" }, { "refsource": "MISC", "name": "https://github.com/bnbdr/wd-rce/", "url": "https://github.com/bnbdr/wd-rce/" } ] } }
