CVE-2022-51022 Details
Description
YiShaAdmin 2.2 through 3.1, fixed in commit 025b062, contains an unauthenticated path traversal vulnerability in the /admin/File/DownloadFile endpoint that allows attackers to read and delete arbitrary files via the filePath parameter. Attackers can send crafted GET requests with directory traversal sequences in filePath and set the delete parameter to read or remove system files like etc/passwd. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-10-20.
A path traversal vulnerability has been identified in YiShaAdmin versions 2.2 through 3.1, excluding the patched version in commit 025b062. The vulnerability exists in the '/admin/File/DownloadFile' endpoint, where unauthenticated users can manipulate the 'filePath' parameter to read or delete arbitrary files, including sensitive system files like '/etc/passwd' and '/etc/shadow'. The issue arises from insufficient validation of the filePath parameter, allowing directory traversal sequences to bypass restrictions. Exploitation of this vulnerability was first reported by the Shadowserver Foundation on October 20, 2023.
Users can update to YiShaAdmin version 3.1.1 or later, where this vulnerability has been fixed.
