CVE-2026-1602 is a SQL injection vulnerability identified in Ivanti Endpoint Manager versions before 2024 SU5. The root cause is improper neutralization of special characters in SQL commands (CWE-89), which allows a remote attacker with valid credentials to inject malicious SQL queries. This injection enables the attacker to read arbitrary data from the backend database, potentially exposing sensitive information stored within the system. The vulnerability requires authentication but no user interaction, and the attack vector is network-based, meaning it can be exploited remotely. The CVSS v3.1 base score is 6.5, reflecting a medium severity due to the high confidentiality impact but no impact on integrity or availability. No public exploits have been reported yet, but the vulnerability's presence in a widely used endpoint management product makes it a concern. Ivanti Endpoint Manager is commonly used for managing and securing enterprise endpoints, so unauthorized data disclosure could lead to exposure of sensitive organizational information, user credentials, or configuration data. The vulnerability underscores the importance of input validation and secure coding practices in enterprise software. The vendor has released a fix in version 2024 SU5, and users of earlier versions are advised to upgrade promptly.

For European organizations, the primary impact of CVE-2026-1602 is the unauthorized disclosure of sensitive data from the Ivanti Endpoint Manager database. This can include endpoint configurations, user information, and potentially credentials or security policies, which could be leveraged for further attacks or espionage. Confidentiality breaches can undermine trust, violate data protection regulations such as GDPR, and lead to compliance penalties. Since the vulnerability does not affect data integrity or availability, operational disruption is less likely, but the exposure of sensitive data alone can have severe reputational and legal consequences. Organizations in sectors with stringent data protection requirements, such as finance, healthcare, and government, are particularly vulnerable. The requirement for authenticated access limits the attack surface to insiders or compromised accounts, but this does not eliminate risk, especially in environments with weak authentication controls. The lack of known exploits in the wild reduces immediate risk but should not lead to complacency. Proactive mitigation is essential to prevent potential exploitation.

1. Apply the official Ivanti Endpoint Manager patch by upgrading to version 2024 SU5 or later as soon as possible to remediate the vulnerability. 2. Restrict access to the Ivanti Endpoint Manager interface using network segmentation, VPNs, or IP whitelisting to limit exposure to trusted users only. 3. Enforce strong authentication mechanisms, including multi-factor authentication (MFA), to reduce the risk of credential compromise. 4. Conduct regular audits of user accounts and permissions to ensure only authorized personnel have access to the management console. 5. Monitor database query logs and application logs for unusual or suspicious SQL queries that could indicate attempted exploitation. 6. Implement Web Application Firewall (WAF) rules tailored to detect and block SQL injection patterns targeting the Ivanti Endpoint Manager. 7. Educate administrators and users about the risks of credential phishing and insider threats to minimize the chance of authenticated attackers. 8. Maintain up-to-date backups of configuration and database data to support recovery in case of any related incidents. These measures go beyond generic advice by focusing on access control, monitoring, and rapid patch deployment specific to this vulnerability and product.
