The application contains a Path Traversal vulnerability (CWE-22) in multiple file operation handlers. An authenticated attacker can bypass directory-level authorisation by injecting traversal sequences into filename components, enabling unauthorised file removal, movement and copying across user boundaries within the same storage mount.
The application disables TLS certificate verification by default for all outgoing storage driver communications, making the system vulnerable to Man-in-the-Middle (MitM) attacks. This enables the complete decryption, theft, and manipulation of all data transmitted during storage operations, severely compromising the confidentiality and integrity of user data.
AList is a file list program that supports multiple storages. AList contains a reflected cross-site scripting vulnerability in helper.go. The endpoint /i/:link_name takes in a user-provided value and reflects it back in the response. The endpoint returns an application/xml response, opening it up to HTML tags via XHTML and thus leading to a XSS vulnerability. This vulnerability is fixed in 3.29.0.
alist <=3.16.3 is vulnerable to Incorrect Access Control. Low privilege accounts can upload any file.
In versions of Alist prior to 3.6.0, a user with only file upload permission can bypass the base path restriction by using '… /' to bypass the base path restriction and upload files to an arbitrary path.
Alist v3.5.1 is vulnerable to Cross Site Scripting (XSS) via the bulletin board.
Alist v3.4.0 is vulnerable to File Upload. A user with only file upload permission can upload any file to any folder (even a password protected one).
