SBA Security Advisory – Filebrowser Insecure Password Handling (CVE-2025-52997)

July 24, 2025

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

SBA Security Advisory – Filebrowser Password Protection of Links Bypassable (CVE-2025-52996)

July 24, 2025

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

SBA Security Advisory – Filebrowser Command Execution Allowlist Bypass (CVE-2025-52995)

July 24, 2025

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

SBA Security Advisory – Filebrowser Command Execution not Limited to Scope (CVE-2025-52904)

July 24, 2025

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

SBA Security Advisory – Filebrowser Shell Commands Can Spawn Other Commands (CVE-2025-52903)

July 24, 2025

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

SBA Security Advisory – Filebrowser Sensitive Data Transferred in URL (CVE-2025-52901)

July 24, 2025

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

SBA Security Advisory – Null pointer dereference in MediaTek Modem (CVE-2025-20647)

June 6, 2025

In the Mediatek modem, there is a possible system crash due to a missing bounds check. This could lead to remote denial of service, if a UE has connected to a rogue base station controlled by the attacker, with no additional execution privileges needed. User interaction is not needed for exploitation. Read More
