CVE-2026-57867 in MicroRealEstate
Summary
by MITRE • 07/07/2026
MicroRealEstate allows adversaries to bypass authentication due to a lack of token state management. This would permit adversaries targeting MicroRealEstate deployments to brute-force One-Time Passwords (OTP) to log in as any user. This issue affects MicroRealEstate: through 1.0.0-alpha3.

Analysis

The vulnerability in MicroRealEstate represents a critical authentication bypass flaw that stems from inadequate token state management within the system's one-time password implementation. This weakness creates a pathway for malicious actors to systematically exploit the authentication mechanism by repeatedly attempting different OTP values without encountering typical rate-limiting or session management controls that would normally prevent such brute force attacks.
The technical nature of this vulnerability places it squarely within the realm of weak session management and authentication flaws, which are commonly categorized under CWE-613. The absence of proper token state tracking means that the system fails to maintain awareness of previously attempted OTP values or enforce time-based restrictions on authentication attempts. This allows attackers to iterate through potential one-time passwords without detection, effectively removing the security benefit that OTPs are designed to provide.
From an operational perspective, this vulnerability presents adversaries with a straightforward path to unauthorized access across all user accounts within the MicroRealEstate deployment. The impact extends beyond individual account compromise as successful brute force attempts could lead to full system infiltration and data exfiltration. The vulnerability affects all versions through 1.0.0-alpha3, indicating that this was likely an overlooked design flaw that persisted through multiple development iterations.
The security implications align with ATT&CK technique T1110.003 for Brute Force Attacks, where adversaries leverage weak authentication controls to gain access to systems. The lack of proper token state management removes essential barriers that would typically slow down or prevent automated attack vectors, making this particular vulnerability highly attractive to threat actors seeking unauthorized system access.
Mitigation strategies should focus on implementing robust session management controls that track authentication attempts and enforce appropriate rate limiting mechanisms. The system requires proper token lifecycle management including expiration times, attempt counters, and temporary account lockout policies. Additionally, implementing multi-factor authentication controls with proper state tracking would significantly reduce the effectiveness of brute force attacks against OTP implementations.
Organizations deploying MicroRealEstate should immediately update to versions that address this vulnerability and implement additional monitoring controls to detect unusual authentication patterns. The fix should include comprehensive token state management that prevents reuse of previously validated tokens and implements intelligent throttling mechanisms to prevent automated attack attempts. Security teams should also consider implementing intrusion detection systems specifically designed to identify brute force attack patterns against authentication systems.
This vulnerability demonstrates the critical importance of proper session management in authentication systems, as outlined in industry best practices for secure application development. The flaw represents a fundamental failure in the security architecture that undermines the core purpose of one-time password mechanisms, which are specifically designed to provide temporary access credentials that cannot be reused or easily guessed through repetitive attempts.
