Detailsinfo

A vulnerability classified as problematic has been found in drakkan SFTPGo up to 2.7.2. Affected is some unknown processing of the component File Download. The manipulation with an unknown input leads to a cookie httponly flag vulnerability. CWE is classifying the issue as CWE-1004. The product uses a cookie to store sensitive information, but the cookie is not marked with the HttpOnly flag. This is going to have an impact on confidentiality. CVE summarizes:

SFTPGo is an open source, event-driven file transfer solution. From 2.2.0 until 2.7.3, the inline query parameter on browsable-share file downloads and authenticated user-file downloads suppresses Content-Disposition: attachment, allowing an attacker-controlled HTML file stored in a share or home directory to be served as text/html in the SFTPGo web origin. An attacker who can place the file can send a crafted link to a victim, and opening that link executes the stored content in the victim's browser context. Exploitation requires social engineering and suitable share or shared-folder access, while HttpOnly session cookies limit direct cookie theft. This issue is fixed in version 2.7.3.
