CVE-2026-24443 is a vulnerability classified under CWE-620 (Unverified Password Change) affecting NETIKUS.NET ltd's EventSentry software prior to version 6.0.1.20. The flaw resides in the Web Reports interface's account management module, where the password change functionality does not require verification of the current password before allowing a new password to be set. This means that an attacker who gains temporary access to an authenticated session—such as through session hijacking, theft, or an unattended workstation—can change the password of the logged-in account without knowing the original credentials. This vulnerability effectively allows an attacker to take persistent control of the account by locking out the legitimate user. If the compromised account has administrative privileges, the attacker can escalate their privileges within the system, potentially gaining full control over EventSentry's monitoring and alerting capabilities. The vulnerability is remotely exploitable over the network without user interaction and requires only low privileges (an authenticated session). The CVSS 4.0 score of 8.6 reflects the high impact on confidentiality and integrity, with no impact on availability. No patches or exploit code are currently publicly available, but the risk remains significant due to the ease of exploitation once an authenticated session is obtained.

The primary impact of CVE-2026-24443 is unauthorized persistent account takeover, which can lead to privilege escalation if administrative accounts are compromised. Organizations relying on EventSentry for monitoring and alerting may face significant operational risks, including unauthorized changes to monitoring configurations, suppression of alerts, or data exfiltration through compromised accounts. The vulnerability undermines the integrity and confidentiality of the affected accounts and the broader monitoring infrastructure. Since EventSentry is used globally in various industries for security and operational monitoring, exploitation could disrupt incident detection and response capabilities. Attackers gaining administrative access could manipulate logs, disable alerts, or create backdoors, severely impacting organizational security posture. The ease of exploitation from any network location where an authenticated session can be hijacked or accessed increases the threat surface. Although no exploits are known in the wild yet, the vulnerability's characteristics make it a high-risk issue that could be targeted in future attacks.

To mitigate CVE-2026-24443, organizations should immediately upgrade EventSentry to version 6.0.1.20 or later where the vulnerability is fixed. In the absence of an available patch, organizations should enforce strict session management controls, including limiting session duration, implementing multi-factor authentication (MFA) to reduce the risk of session hijacking, and monitoring for unusual account activity. Network segmentation and access controls should restrict access to the Web Reports interface to trusted users and networks only. Additionally, organizations should audit existing accounts for unauthorized password changes and review logs for suspicious activity. Employing endpoint security measures to prevent session theft and educating users on securing their sessions can further reduce risk. Finally, consider implementing additional verification steps for password changes at the application or proxy level if possible, such as requiring re-authentication or out-of-band confirmation.
