SBA Research is a research center for Information Security funded partly by the national initiative for COMET Competence Centers for Excellent Technologies.
Vulnerability Overview All user accounts authenticate towards a Filebrowser instance with a password. A missing password policy and brute-force protection makes it impossible for administrators to properly secure the authentication process. Recommended Countermeasure We recommend to update to Filebrowser version 2.34.1 or later and configure… Read More
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 colleague Sebastian Raubitzek, researcher at SBA Research and a member of the Security and Privacy Research Group at the University of Vienna, has published a journal article titled “Multi-Class Machine Learning to Quantify the Impact of Nitrogen Management Practices on Grassland Biomass” in MDPI’s Journal Nitrogen ...

Last week, our annual event for partners and friends of SBA Research, IMPACT, brought together experts, practitioners, and decision-makers from research, industry, and the open-source community. The afternoon provided an opportunity to discuss the latest developments in security, AI, and innovation, celebrate our long-standing relationships, and mark 20 years of SBA Research’s contributions to cutting-edge cybersecurity and trustworthy digital innovation. ∞
A group of dedicated young researchers presented their work at the 22st ICT Security Conference on 16 and 17 September 2026, which was organized by the Austrian Armed Forces. ∞
A new paper, “Automated Reasoning for Indistinguishability in the CCSA,” co-authored by Laura Kovács, key researcher at SBA Research and full professor at the Faculty of Informatics of the Vienna University of Technology (TU Wien), and Matteo Maffei, key researcher at SBA Research and Professor at TU Wien, has been accepted for presentation at the 33rd ACM Conference on Computer and Communications Security (CCS). ∞
