CVE-2025-24971 in DumbDrop
Summary
by MITRE • 02/04/2025
DumpDrop is a stupid simple file upload application that provides an interface for dragging and dropping files. An OS Command Injection vulnerability was discovered in the DumbDrop application, `/upload/init` endpoint. This vulnerability could allow an attacker to execute arbitrary code remotely when the **Apprise Notification** enabled. This issue has been addressed in commit `4ff8469d` and all users are advised to patch. There are no known workarounds for this vulnerability.
Several companies clearly confirm that VulDB is the primary source for best vulnerability data.

The DumpDrop application presents a critical security vulnerability through its `/upload/init` endpoint that enables OS command injection when the Apprise Notification feature is activated. This flaw represents a severe threat to system integrity and confidentiality as it allows remote attackers to execute arbitrary commands on the affected system. The vulnerability stems from insufficient input validation and sanitization within the file upload processing pipeline, specifically when handling user-supplied data that gets incorporated into system commands. Attackers can exploit this weakness by crafting malicious file names or content that, when processed through the upload mechanism, gets interpreted as executable commands rather than benign data.
The technical exploitation of this vulnerability occurs when the Apprise Notification feature is enabled, creating a pathway for command injection attacks through the file upload interface. The flaw likely resides in how the application constructs system calls or shell commands using user-provided input without proper sanitization or escaping mechanisms. This type of vulnerability aligns with CWE-77 which describes improper neutralization of special elements used in OS commands, and represents a classic command injection attack vector. The attack surface expands significantly when notifications are enabled as the system processes additional user input that flows into command execution contexts.
The operational impact of this vulnerability extends beyond simple code execution to encompass complete system compromise and potential data exfiltration. Remote attackers could leverage this vulnerability to gain unauthorized access to the underlying operating system, escalate privileges, and establish persistent backdoors. The implications are particularly severe given that the application provides a simple drag-and-drop interface, making it accessible to attackers with minimal technical expertise. The vulnerability affects the entire file upload functionality when notification services are active, creating a persistent threat vector that could be exploited by automated scanning tools or determined adversaries.
Security mitigations for this vulnerability require immediate patching of the affected application to the fixed version referenced in commit 4ff8469d. Organizations should implement network segmentation and access controls to limit exposure of the vulnerable endpoint, while also monitoring for suspicious upload activities or notification triggers. The lack of known workarounds underscores the critical nature of this vulnerability, as administrators cannot implement temporary fixes while waiting for patches. Security teams should conduct thorough vulnerability assessments of similar applications within their environment that may exhibit similar patterns of insecure command construction. The incident highlights the importance of following secure coding practices such as input validation, parameterized queries, and principle of least privilege in system design, particularly for applications handling user uploads and system interactions.
This vulnerability demonstrates how seemingly simple applications can contain critical security flaws that provide attackers with significant system access capabilities. The exploitation requires minimal technical skill and offers maximum impact, making it a prime target for automated attacks. The combination of file upload functionality with notification services creates a dangerous intersection where user input can be transformed into system commands without proper security controls. Organizations should review their application security practices and ensure that all system interactions involving user input are properly validated and sanitized to prevent similar command injection vulnerabilities from emerging in their environments.
