Summary
Successful exploitation of these vulnerabilities could allow an attacker to execute arbitrary shell commands and the disclosure of sensitive system information.
The following versions of Ilevia EVE X1 Server are affected:
- EVE X1 <=4.7.18.0 (CVE-2025-34185, CVE-2025-34184, CVE-2025-34183, CVE-2025-34186, CVE-2025-34187, CVE-2025-34517, CVE-2025-34518, CVE-2025-34512, CVE-2025-34513)
| CVSS | Vendor | Equipment | Vulnerabilities |
|---|---|---|---|
| v3 9.8 | Ilevia | Ilevia EVE X1 Server | Improper Limitation of a Pathname to a Restricted Directory (‘Path Traversal’), Improper Neutralization of Special Elements used in an OS Command (‘OS Command Injection’), Insertion of Sensitive Information into Log File, Improper Neutralization of Input During Web Page Generation (‘Cross-site Scripting’) |
Background
- Critical Infrastructure Sectors: Critical Manufacturing
- Countries/Areas Deployed: Worldwide
- Company Headquarters Location: Italy
Vulnerabilities
CVE-2025-34183
Ilevia EVE X1 Server contains a vulnerability in its server-side logging mechanism that allows unauthenticated remote attackers to retrieve plaintext credentials from exposed .log files. This flaw enables full authentication bypass and system compromise through credential reuse.
Affected Products
Ilevia EVE X1 Server
Vendor:
Ilevia
Product Version:
Ilevia EVE X1: <=4.7.18.0
Product Status:
known_affected
Relevant CWE: CWE-532 Insertion of Sensitive Information into Log File
Metrics
CVE-2025-34186
Ilevia EVE X1/X5 Server contains a vulnerability in its authentication mechanism. Unsanitized input is passed to a system() call for authentication, allowing attackers to inject special characters and manipulate command parsing. Due to the binary’s interpretation of non-zero exit codes as successful authentication, remote attackers can bypass authentication and gain full access to the system.

Relevant CWE: CWE-78 Improper Neutralization of Special Elements used in an OS Command (‘OS Command Injection’)
Metrics
CVE-2025-34187
Ilevia EVE X1/X5 Server contains a misconfiguration in the sudoers file that allows passwordless execution of certain Bash scripts. If these scripts are writable by web-facing users or accessible via command injection, attackers can replace them with malicious payloads. Execution with sudo grants full root access, resulting in remote privilege escalation and potential system compromise.

Recommended Practices
CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities, such as:
Minimize network exposure for all control system devices and/or systems, ensuring they are not accessible from the internet.
Locate control system networks and remote devices behind firewalls and isolating them from business networks.
When remote access is required, use more secure methods, such as Virtual Private Networks (VPNs), recognizing VPNs may have vulnerabilities and should be updated to the most current version available. Also recognize VPN is only as secure as the connected devices.
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices on the ICS webpage on cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets.
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B–Targeted Cyber Intrusion Detection and Mitigation Strategies.
Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.
CISA also recommends users take the following measures to protect themselves from social engineering attacks:
Do not click web links or open attachments in unsolicited email messages.
Refer to Recognizing and Avoiding Email Scams for more information on avoiding email scams.
Refer to Avoiding Social Engineering and Phishing Attacks for more information on social engineering attacks.
No known public exploitation specifically targeting these vulnerabilities has been reported to CISA at this time.
