CVE-2025-2415 is a high-severity 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 categorized under CWE-307, which pertains to improper restriction of excessive authentication attempts. This flaw allows an attacker to bypass authentication mechanisms by exploiting the lack of effective controls on the number of login attempts. Because the vulnerability does not require any privileges or user interaction (as indicated by CVSS vector AV:N/AC:L/PR:N/UI:N), it can be exploited remotely over the network without authentication. The impact of successful exploitation includes full confidentiality compromise, partial integrity loss, and partial availability degradation of the affected system. The vulnerability arises due to the failure of MyRezzta to limit or throttle repeated authentication attempts, enabling brute force or automated attacks that can circumvent authentication protections. This can lead to unauthorized access to sensitive business data, manipulation of reservation or customer information, and potential disruption of service availability. Although no known exploits are currently reported in the wild, the high CVSS score of 8.6 reflects the significant risk posed by this vulnerability if weaponized. The absence of published patches at the time of reporting further elevates the urgency for mitigation.

For European organizations using Akinsoft MyRezzta, particularly those in the hospitality, event management, or reservation sectors, this vulnerability poses a critical risk. Unauthorized access could lead to exposure of personal customer data, including payment and identification information, violating GDPR and other data protection regulations. The integrity of reservation records could be compromised, resulting in operational disruptions and financial losses. Availability impacts, while partial, could degrade service quality and customer trust. Given the remote and unauthenticated nature of the exploit, attackers could target multiple organizations en masse, increasing the risk of widespread data breaches. The reputational damage and regulatory penalties associated with such breaches could be severe. Additionally, the vulnerability could be leveraged as a foothold for further lateral movement within corporate networks, amplifying the threat landscape for affected entities.

European organizations should immediately assess their deployment of Akinsoft MyRezzta to identify affected versions. Until an official patch is released, implement compensating controls such as network-level access restrictions to the MyRezzta authentication interfaces, including IP whitelisting and VPN requirements. Deploy Web Application Firewalls (WAFs) with rules to detect and block excessive authentication attempts and brute force patterns. Enable multi-factor authentication (MFA) if supported by the application or integrate it via proxy solutions to add an additional layer of security. Monitor authentication logs closely for unusual login activity and implement alerting for repeated failed attempts. Conduct internal penetration testing to verify the effectiveness of these controls. Plan for rapid deployment of the vendor’s patch once available and maintain communication with Akinsoft for updates. Additionally, review and reinforce incident response plans to address potential exploitation scenarios.
