Vulnerability Overview Files managed by Filebrowser can be shared with a link to external persons. While the application allows protecting those links with a password, the implementation is error-prone, making an incidental unprotected sharing of a file possible. Recommended Countermeasure We recommend to update to… Read More
Vulnerability Overview The Command Execution feature of Filebrowser only allows the execution of shell commands which have been predefined on a user-specific allowlist. The implementation of this allowlist is erroneous, allowing a user to execute additional commands not permitted. Recommended Countermeasure We recommend to update… Read More
Vulnerability Overview In the web application, all users have a scope assigned, and they only have access to the files within that scope. The Command Execution feature of Filebrowser allows the execution of shell commands which are not restricted to the scope, potentially giving an attacker read and write access… Read More
Vulnerability Overview The Command Execution feature of Filebrowser only allows the execution of shell command which have been predefined on a user-specific allowlist. Many tools allow the execution of arbitrary different commands, rendering this limitation void. Recommended Countermeasure We recommend to disable the… Read More
Vulnerability Overview The Markdown preview function of Filebrowser v2.32.0 is vulnerable to Stored Cross-Site-Scripting (XSS). Any JavaScript code that is part of a Markdown file uploaded by a user will be executed by the browser. Recommended Countermeasure We recommend to update to Filebrowser version 2.33.7… Read More
Vulnerability Overview URLs that are accessed by a user are commonly logged in many locations, both server- and client-side. It is thus good practice to never transmit any secret information as part of a URL. Filebrowser violates this practice, since access tokens are used as GET parameters. Read More
Vulnerability Overview The file access permissions for files uploaded to or created from Filebrowser are never explicitly set by the application. The same is true for the database used by Filebrowser. On standard servers where the umask configuration has not been hardened before, this makes all the stated files readable… Read More
Our colleague Bernhard Garn, researcher at SBA Research, gave a talk on "Improving the Security of Quantum Platforms using Combinatorial Methods" at the Workshop on Secure Protocol Implementations in the Quantum Era (SPIQE) on June 24th, in Munich, Germany. ... Read More
Our colleagues Philip König, Sebastian Raubitzek, Dennis Toth, Fabian Obermann and Kevin Mallinger published a new paper on Boost-Classifier-Driven Fault Prediction Across Heterogeneous Open-Source Repositories. In this paper they analyzed over 2.4 million commits from 33 open-source projects… Read More
A group of dedicated young researchers presented their work at the 21st ICT Security Conference on 25 and 26 June 2025, which was organized by the Austrian Armed Forces. They impressed the audience with their… Read More
