CVE-2026-54209 in TeamDavid
Summary
by MITRE • 08/07/2026
Tobit Laboratories AG TeamDavid's Webbox application handles password changes using a function triggered by including the string "(editini)" in the file path, writing the new password to the specified "Archive.ini" file. However, the application does not verify that the provided path actually refers to an "Archive.ini" file. If an attacker specifies a different file with excessive size, a buffer overflow occurs. This vulnerability allows an unauthenticated attacker to crash the server, resulting in denial of service. This issue affects TeamDavid through Rollout 524.

The vulnerability in TeamDavid's Webbox application represents a critical buffer overflow condition that stems from inadequate input validation within the password change functionality. The flaw manifests when the application processes requests containing the string "(editini)" in the file path, specifically targeting the Archive.ini configuration file for password modifications. This design oversight creates an attack surface where malicious actors can manipulate file paths to target arbitrary files instead of being restricted to the intended configuration file. The vulnerability operates under CWE-121, which categorizes buffer overflow conditions as a fundamental weakness in software design that allows attackers to overwrite adjacent memory locations.
The technical implementation of this vulnerability demonstrates poor path validation mechanisms within the application's file handling routines. When an attacker supplies a malicious file path through the password change function, the system fails to perform proper file type verification or path sanitization checks before proceeding with file operations. This absence of validation allows the application to accept any file path, regardless of whether it points to an Archive.ini file or another arbitrary file location. The buffer overflow occurs specifically when excessive file sizes are provided, causing memory allocation issues that result in application instability and potential crash conditions.
From an operational perspective, this vulnerability presents a significant denial of service threat that can be exploited by unauthenticated attackers without requiring any privileged access or credentials. The impact extends beyond simple service disruption as the application becomes unavailable to legitimate users who require password change functionality. This vulnerability affects all versions of TeamDavid's Webbox through Rollout 524, indicating a persistent flaw that has not been addressed in the affected release cycle. The attack vector requires minimal technical expertise and can be executed remotely, making it particularly dangerous for publicly accessible web applications.
The security implications of this vulnerability align with ATT&CK technique T1499.004, which covers network denial of service attacks through resource exhaustion or application crashes. Organizations utilizing TeamDavid's Webbox application face potential operational disruption that could affect business continuity and user access to critical services. The vulnerability also demonstrates weaknesses in the principle of least privilege and input validation that should be addressed through proper security development lifecycle practices. Mitigation strategies should include immediate patching of affected versions, implementation of proper path validation mechanisms, and enforcement of file type restrictions within the application's configuration handling routines.
Effective remediation requires comprehensive code review to identify similar path traversal vulnerabilities throughout the application architecture. The solution must implement strict file path validation that verifies target files are indeed Archive.ini configuration files before processing operations. Additionally, input sanitization measures should be implemented to prevent oversized file specifications from causing buffer overflow conditions. Organizations should also consider implementing application-level firewalls or intrusion detection systems to monitor for suspicious file path patterns and potential exploitation attempts. The vulnerability serves as a reminder of the critical importance of proper input validation and secure coding practices in preventing remote code execution and denial of service attacks.
