CVE-2026-94594 in One
Summary
by MITRE • 10/03/2026
Armatura One's message broker logs client connection credentials and the associated password in plain text during normal operation. Any party with read access to this log, or to a backup or support bundle that includes it, can obtain the logged credential.

The vulnerability identified within Armatura One involves the insecure storage of authentication material through improper logging practices. During standard operational procedures, the message broker component records client connection credentials alongside their corresponding passwords in plain text format within system logs. This behavior represents a fundamental failure to adhere to secure coding standards regarding sensitive data handling, specifically failing to mask or hash password fields before persistence. The presence of plaintext credentials in log files creates a significant attack surface for any entity that gains read access to the file system where these logs are stored.
From a technical perspective, this flaw aligns with CWE-532, which classifies information exposure through log files as a critical security weakness. When an application writes sensitive data such as passwords directly to standard output or log destinations without sanitization, it bypasses essential confidentiality controls. In many enterprise environments, log aggregation systems are configured to collect and store logs for monitoring and debugging purposes. If these aggregated logs are not subject to the same strict access control policies as the source files, the plaintext credentials become accessible to a broader set of users or services than intended by the application's security model.
The operational impact of this vulnerability is severe due to the potential for credential compromise leading to unauthorized access. Any party with read permissions on the log directory can extract these passwords directly from the text files. Furthermore, the risk extends beyond active logs to include archived data and support bundles. System backups or diagnostic archives often contain copies of current log states. If an attacker obtains a backup file or if a user generates a support bundle for troubleshooting purposes without realizing it contains plaintext credentials, those secrets are exposed outside the immediate operational environment. This can facilitate lateral movement within a network, privilege escalation, or direct compromise of downstream services that rely on Armatura One for message routing and authentication.
This issue also correlates with MITRE ATT&CK technique T1078, Valid Accounts, as it provides attackers with legitimate credentials to authenticate against the system. Additionally, it relates to CWE-256, which covers problems with storing passwords in a recoverable format. The exposure of these credentials undermines the integrity and confidentiality guarantees expected from an enterprise message broker. Attackers can use harvested plaintext passwords to bypass authentication mechanisms entirely, effectively rendering other security controls such as multi-factor authentication or complex password policies less effective if those same credentials are reused across systems.
To mitigate this vulnerability, immediate remediation should focus on modifying the logging configuration of Armatura One to exclude sensitive fields from log output. Developers must implement data masking techniques that replace password values with asterisks or null strings before they are written to any log stream. It is also critical to review existing logs and backups for residual plaintext credentials and securely delete them using cryptographic erasure methods where possible. Access controls on the directories containing these logs should be strictly limited to essential system processes, employing principle of least privilege to minimize the number of entities with read access. Regular security audits and static code analysis tools configured to detect CWE-532 patterns can help prevent similar issues in future updates or related components within the Armatura One ecosystem.
