CVE-2026-54218 in TeamDavid
Summary
by MITRE • 08/07/2026
Use of hard-coded cryptographic key vulnerability in Tobit Laboratories AG TeamDavid's Webbox. For users created locally in David, passwords are stored in various files using only obfuscation. Any user with access to the server’s file system, or who can otherwise extract files from the server (see vulnerability “Random File Read”), can potentially obtain affected users’ passwords. This issue affects TeamDavid through Rollout 524.

The vulnerability in Tobit Laboratories AG TeamDavid's Webbox represents a critical cryptographic weakness that undermines the security of user authentication mechanisms. This flaw manifests as the use of hard-coded cryptographic keys within the system's password storage infrastructure, creating a fundamental breach in the security model that protects user credentials. The implementation fails to employ proper cryptographic practices, instead relying on obfuscation techniques that provide minimal security protection against determined attackers who can access the underlying file system.
The technical implementation of this vulnerability stems from the application's design where locally created users have their passwords stored across multiple files using only basic obfuscation methods rather than robust encryption. This approach violates established cryptographic best practices and creates a scenario where sensitive authentication data becomes accessible to any entity with sufficient privileges to read the affected system files. The hard-coded nature of the cryptographic keys means that the encryption mechanism itself is compromised, as these keys are embedded within the application code or configuration files, making them discoverable through reverse engineering or direct file access.
The operational impact of this vulnerability extends beyond simple credential theft, as it creates a persistent security risk that affects all users whose credentials are stored in this manner. Attackers who gain file system access can extract password data without requiring additional authentication mechanisms, effectively bypassing the normal security controls that should protect user accounts. This vulnerability particularly affects TeamDavid installations through Rollout 524, indicating a specific version range where the cryptographic implementation was flawed, making organizations running these versions especially vulnerable to credential compromise attacks.
This weakness aligns with CWE-320, which addresses the use of hard-coded cryptographic keys in security implementations, and represents a direct violation of the principle of proper key management. The vulnerability also maps to ATT&CK technique T1566, specifically focusing on credential access through unauthorized access to system files and data stores. Organizations affected by this issue face significant risk of account takeover, lateral movement within their networks, and potential data breaches as attackers can leverage these compromised credentials to gain deeper system access.
The remediation approach requires immediate implementation of proper cryptographic key management practices, including the replacement of hard-coded keys with dynamically generated encryption materials and the adoption of secure password storage mechanisms. Organizations should implement proper key rotation procedures, utilize hardware security modules where possible, and ensure that all authentication data is protected through industry-standard encryption algorithms rather than simple obfuscation techniques. The vulnerability highlights the critical importance of following established security frameworks such as NIST SP 800-57 for cryptographic key management and emphasizes the need for regular security assessments to identify similar implementation flaws in legacy systems.
