CVE-2026-105324 Crítica · 9.2 CWE-113 06/10/2026

An HTTP header injection vulnerability was found in the ADM

An HTTP header injection vulnerability in start-page-loader.cgi of ADM allows an unauthenticated remote attacker to read arbitrary files on the host system. By sending a crafted HTTP request with injected headers via the state parameter, the attacker can leverage the underlying web server's X-Sendfile mechanism to retrieve sensitive files without authentication. Affected products and versions include: from ADM 4.1.0 through ADM 4.3.3.RWC1 as well as from ADM 5.0.0 through ADM 5.1.4.RL21.

CVE-2026-6644 Crítica · 9.1 CWE-78 20/04/2026

A command injection vulnerability was found in the PPTP VPN Clients on the ADM

A command injection vulnerability was found in the PPTP VPN Clients on the ADM. The vulnerability allows an administrative user to break out of the restricted web environment and execute arbitrary code on the underlying operating system. This occurs due to insufficient validation of user-supplied input before it is passed to a system shell. Successful exploitation allows an attacker to achieve Remote Code Execution (RCE) and fully compromise the system. Affected products and versions include: from ADM 4.1.0 through ADM 4.3.3.RR42 as well as from ADM 5.0.0 through ADM 5.1.2.REO1.

CVE-2026-6643 Crítica · 9.9 CWE-121 20/04/2026

A stack-based buffer overflow vulnerability in the VPN Clients on the ADM

A stack-based buffer overflow vulnerability was found in the VPN Clients on the ADM. The issue stems from the use of unbounded sscanf() and passing user-controlled data directly to printf(). Due to the lack of PIE and Stack Canary protections, an authenticated remote attacker can exploit these to execute arbitrary code as the web server user. Affected products and versions include: from ADM 4.1.0 through ADM 4.3.3.RR42 as well as from ADM 5.0.0 through ADM 5.1.2.REO1.

CVE-2026-3179 Alta · 8.1 CWE-22 25/02/2026

A path traversal vulnerability was found in the FTP Backup on the ADM.

The FTP Backup on the ADM does not properly sanitize filenames received from the FTP server when parsing directory listings. A malicious server or MITM attacker can craft filenames containing path traversal sequences, causing the client to write files outside the intended backup directory. A path traversal vulnerability may allow an attacker to overwrite arbitrary files on the system and potentially achieve privilege escalation or remote code execution. Affected products and versions include: from ADM 4.1.0 through ADM 4.3.3.ROF1 as well as from ADM 5.0.0 through ADM 5.1.2.RE51.

CVE-2026-3100 Média · 6.5 CWE-295 25/02/2026

An improper certificate validation vulnerability was found in the FTP Backup on the ADM.

The FTP Backup on the ADM will not properly strictly enforce TLS certificate verification while connecting to an FTP server using FTPES/FTPS. An improper validated TLS/SSL certificates allows a remote attacker can intercept network traffic to perform a Man-in-the-Middle (MitM) attack, which may intercept, modify, or obtain sensitive information such as authentication credentials and backup data. Affected products and versions include: from ADM 4.1.0 through ADM 4.3.3.ROF1 as well as from ADM 5.0.0 through ADM 5.1.2.RE51.

CVE-2026-24936 Crítica · 9.8 CWE-20 03/02/2026

ASUSTOR ADM: Validação Inadequada de Entrada em Programa CGI Permite Escrita Arbitrária de Arquivos

Quando uma função específica está habilitada durante a ingressão em um domínio AD a partir do ADM, uma vulnerabilidade de validação inadequada de parâmetros de entrada em um programa CGI específico permite que um atacante remoto não autenticado escreva dados arbitrários em qualquer arquivo do sistema. Ao explorar essa vulnerabilidade, atacantes podem sobrescrever arquivos críticos do sistema, levando a um comprometimento completo do sistema. Produtos e versões afetados incluem: do ADM 4.1.0 até o ADM 4.3.3.ROF1, bem como do ADM 5.0.0 até o ADM 5.1.1.RCI1.

CVE-2026-24935 Média · 5.6 CWE-295 03/02/2026

An improper certificate validation vulnerability was found in a third-party NAT traversal module.

A third-party NAT traversal module fails to validate SSL/TLS certificates when connecting to the signaling server. While subsequent access to device services requires additional authentication, a Man-in-the-Middle (MitM) attacker can intercept or redirect the NAT tunnel establishment. This could allow an attacker to disrupt service availability or facilitate further targeted attacks by acting as a proxy between the user and the device services. Affected products and versions include: from ADM 4.1.0 through ADM 4.3.3.ROF1 as well as from ADM 5.0.0 through ADM 5.1.1.RCI1.

CVE-2026-24934 Baixa · 3.7 CWE-295 03/02/2026

An improper certificate validation vulnerability was found in ADM while querying an external server for the device's WAN IP address.

The DDNS function uses an insecure HTTP connection or fails to validate the SSL/TLS certificate when querying an external server for the device's WAN IP address. An unauthenticated remote attacker can perform a Man-in-the-Middle (MitM) attack to spoof the response, leading the device to update its DDNS record with an incorrect IP address. Affected products and versions include: from ADM 4.1.0 through ADM 4.3.3.ROF1 as well as from ADM 5.0.0 through ADM 5.1.1.RCI1.

CVE-2026-24933 Média · 5.9 CWE-295 03/02/2026

An improper certificate validation vulnerability was found in ADM while sending HTTPS requests to the server.

The API communication component fails to validate the SSL/TLS certificate when sending HTTPS requests to the server. An improper certificates validation vulnerability allows an unauthenticated remote attacker can perform a Man-in-the-Middle (MitM) attack to intercept the cleartext communication, potentially leading to the exposure of sensitive user information, including account emails, MD5 hashed passwords, and device serial numbers. Affected products and versions include: from ADM 4.1.0 through ADM 4.3.3.ROF1 as well as from ADM 5.0.0 through ADM 5.1.1.RCI1.

CVE-2026-24932 Média · 5.9 CWE-295 03/02/2026

An improper certificate validation vulnerability was found in ADM while updating the DDNS settings.

The DDNS update function in ADM fails to properly validate the hostname of the DDNS server's TLS/SSL certificate. Although the connection uses HTTPS, an improper validated TLS/SSL certificates allows a remote attacker can intercept the communication to perform a Man-in-the-Middle (MitM) attack, which may obtain the sensitive information of DDNS updating process, including the user's account email, MD5 hashed password, and device serial number.This issue affects ADM: from 4.1.0 through 4.3.3.ROF1, from 5.0.0 through 5.1.1.RCI1.

CVE-2025-13053 Baixa · 3.7 CWE-311 12/12/2025

A missing encryption of sensitive data vulnerability was found in the UPS settings of ADM

When a user configures the NAS to retrieve UPS status or control the UPS, a non-enforced TLS certificate verification can allow an attacker able to intercept network traffic between the client and server can perform a man-in-the-middle (MITM) attack, which may obtain the sensitive information of the UPS server configuation. This issue affects ADM: from 4.1.0 through 4.3.3.RKD2, from 5.0.0 through 5.1.0.RN42.

CVE-2025-13052 Média · 5.9 CWE-295 12/12/2025

An improper certificates validation vulnerability was found in the Notification settings of ADM

When the user set the Notification's sender to send emails to the SMTP server via msmtp, an improper validated TLS/SSL certificates allows an attacker who can intercept network traffic between the SMTP client and server to execute a man-in-the-middle (MITM) attack, which may obtain the sensitive information of the SMTP. Affected products and versions include: from ADM 4.1.0 through ADM 4.3.3.RKD2 as well as from ADM 5.0.0 through ADM 5.1.0.RN42.
