CVE-2026-24443 in EventSentry
Summary
by MITRE • 02/24/2026
EventSentry versions prior to 6.0.1.20 contain an unverified password change vulnerability in the account management functionality of the Web Reports interface. The password change mechanism does not require validation of the current password before allowing a new password to be set. An attacker who gains temporary access to an authenticated user session can change the account password without knowledge of the original credentials. This enables persistent account takeover and, if administrative accounts are affected, may result in privilege escalation.

The vulnerability identified as CVE-2026-24443 represents a critical authentication flaw within EventSentry Web Reports interface versions prior to 6.0.1.20. This weakness stems from inadequate input validation and authentication flow implementation that permits unauthorized password modifications without proper credential verification. The vulnerability specifically targets the account management functionality where users can reset their passwords through the web interface. The flaw creates a dangerous condition where any authenticated user session can be exploited to modify account credentials without knowledge of the original password, fundamentally undermining the security model of the application.
The technical implementation of this vulnerability resides in the password change mechanism's failure to enforce proper authentication checks before allowing credential modifications. According to CWE-614, this represents a weakness in the authentication process where sensitive functions are accessible without proper verification of the current password. The flaw operates at the application layer and specifically affects the web-based administrative interface where users can manage their accounts. Attackers can exploit this vulnerability by intercepting or obtaining a valid session token from an authenticated user, then leveraging this session to change the password without requiring the original credentials or security questions. This vulnerability directly violates the principle of least privilege and authentication requirements established in security frameworks.
The operational impact of this vulnerability extends beyond simple account compromise to enable persistent access and potential privilege escalation within the system. Once an attacker successfully changes a password, they gain indefinite access to the compromised account, effectively bypassing any additional authentication measures that might have been in place. If administrative accounts are targeted, this vulnerability can lead to complete system compromise and unauthorized access to sensitive data and system resources. The attack vector is particularly concerning because it requires minimal privileges to exploit, as the attacker only needs a valid session token rather than administrative credentials. This vulnerability can be exploited through session hijacking techniques and represents a significant risk to organizations relying on EventSentry for system monitoring and security management.
Mitigation strategies for this vulnerability should focus on immediate implementation of proper authentication controls and session management practices. Organizations should upgrade to EventSentry version 6.0.1.20 or later where this vulnerability has been addressed through proper password verification mechanisms. The fix should enforce mandatory current password validation before allowing password changes, aligning with the security principle that sensitive operations require confirmation of existing credentials. Additionally, implementing robust session management practices including session timeout mechanisms and secure session token handling can help reduce the attack surface. Organizations should also consider implementing multi-factor authentication for administrative accounts and monitoring for unauthorized password change activities. According to ATT&CK framework, this vulnerability maps to T1078 (Valid Accounts) and T1566 (Phishing), as it enables attackers to maintain persistence through account takeover and can be exploited through session hijacking techniques. Regular security assessments and penetration testing should be conducted to identify similar authentication bypass vulnerabilities in other applications within the organization's infrastructure.
