CVE-2025-1740 is a critical vulnerability identified in Akinsoft's MyRezzta software, specifically affecting versions from s2.03.01 up to but not including v2.05.01. The vulnerability is classified under CWE-307, which pertains to improper restriction of excessive authentication attempts. This flaw allows attackers to bypass authentication mechanisms by exploiting the lack of effective controls on repeated login attempts. Consequently, an attacker can perform brute force attacks or exploit password recovery functionalities to gain unauthorized access to the system. The vulnerability does not require any privileges or user interaction and can be exploited remotely over the network. The CVSS v3.1 base score of 9.8 (critical) reflects the high impact on confidentiality, integrity, and availability, as successful exploitation could lead to full system compromise, data theft, or disruption of services. The absence of patch links suggests that a fix may not yet be publicly available, increasing the urgency for mitigation. The vulnerability affects the authentication logic of MyRezzta, a software product by Akinsoft, which is likely used in business or enterprise environments for resource or reservation management. The improper restriction on authentication attempts means that rate limiting, account lockout, or other throttling mechanisms are either missing or insufficient, enabling attackers to systematically guess credentials or abuse password recovery processes without being blocked or detected effectively.

For European organizations using Akinsoft MyRezzta, this vulnerability poses a significant risk. Unauthorized access through brute force or password recovery exploitation can lead to data breaches involving sensitive customer or business information, financial losses, and operational disruptions. Given the critical severity, attackers could gain administrative privileges, manipulate data integrity, or cause denial of service by locking out legitimate users or corrupting system states. Industries relying on MyRezzta for managing reservations or resources—such as hospitality, event management, or service providers—may experience direct operational impact. Additionally, compromised systems could be leveraged as entry points for lateral movement within corporate networks, increasing the risk of broader cyberattacks. The lack of known exploits in the wild currently reduces immediate threat but does not diminish the urgency, as attackers often develop exploits rapidly once vulnerabilities are disclosed. European data protection regulations like GDPR impose strict requirements on data security; exploitation of this vulnerability could lead to regulatory penalties and reputational damage if personal data is exposed.

Organizations should prioritize upgrading MyRezzta to version 2.05.01 or later once available, as this likely contains the necessary patches to address the vulnerability. Until patches are released, implement compensating controls such as deploying web application firewalls (WAFs) with rules to detect and block brute force attempts targeting MyRezzta login endpoints. Enforce network-level rate limiting and IP blacklisting to reduce the feasibility of automated attacks. Strengthen authentication by integrating multi-factor authentication (MFA) if supported by MyRezzta or via external identity providers. Monitor authentication logs closely for unusual patterns indicative of brute force or password recovery abuse. Conduct regular security audits and penetration testing focused on authentication mechanisms. If possible, restrict access to MyRezzta interfaces to trusted networks or VPNs to reduce exposure. Educate users on strong password policies and the risks of password reuse. Finally, maintain up-to-date backups and incident response plans to mitigate potential damage from exploitation.
