CVE-2025-2222: Information Disclosure Vulnerability

CVE-2025-2222 Overview

CVE-2025-2222 is a CWE-552 (Files or Directories Accessible to External Parties) vulnerability affecting Schneider Electric products. This vulnerability exists over HTTPS connections and could allow an attacker to leak sensitive information and potentially achieve privilege escalation following a man-in-the-middle attack.

The vulnerability enables unauthorized access to files or directories that should be restricted to internal parties only. When exploited, an attacker positioned on the network could intercept HTTPS communications and leverage the exposed resources to extract confidential data or escalate their privileges within the affected system.

Critical Impact

This vulnerability could result in information disclosure and privilege escalation through network-based man-in-the-middle attacks, potentially compromising industrial control systems and critical infrastructure.

Affected Products

• Schneider Electric industrial products (refer to Schneider Electric Security Notice for complete product list)

Technical Details for CVE-2025-2222

Vulnerability Analysis

This vulnerability is classified under CWE-552, which describes a condition where files or directories are made accessible to actors outside of the intended security context. In this case, the flaw exists within the HTTPS implementation of affected Schneider Electric products.

The vulnerability allows external parties to access files or directories that should be restricted. When combined with a man-in-the-middle (MITM) attack scenario, an adversary can exploit this weakness to intercept communications and potentially extract sensitive configuration files, credentials, or system information that could facilitate further attacks.

The network-based attack vector with no required privileges or user interaction makes this vulnerability particularly concerning for industrial control system (ICS) environments where Schneider Electric products are commonly deployed.

Root Cause

The root cause of CVE-2025-2222 stems from improper access controls on files and directories exposed over HTTPS connections. The affected system fails to adequately restrict access to sensitive resources, allowing unauthorized external parties to access files that should be protected. This improper restriction of file access, combined with potential weaknesses in the HTTPS implementation, creates the conditions necessary for information leakage and privilege escalation attacks.

Attack Vector

The attack vector for this vulnerability is network-based, requiring the attacker to position themselves in a man-in-the-middle scenario. The exploitation process involves:

1. The attacker establishes a position on the network between the target system and legitimate clients
2. The attacker intercepts HTTPS traffic to and from the vulnerable Schneider Electric device
3. By exploiting the file access vulnerability, the attacker can retrieve sensitive files or directories that are improperly exposed
4. Information gathered from these files can be used to escalate privileges or launch additional attacks against the industrial control system

The attack complexity is moderate, as it requires network positioning for the MITM component, but no authentication or user interaction is required to exploit the underlying file access vulnerability.

Detection Methods for CVE-2025-2222

Indicators of Compromise

• Unusual HTTPS requests targeting configuration files or system directories
• Unexpected file access patterns on affected Schneider Electric devices
• Network anomalies suggesting man-in-the-middle positioning between clients and industrial control systems
• Authentication failures or unexpected privilege changes following network interception events

Detection Strategies

• Monitor network traffic for suspicious HTTPS requests to sensitive file paths on Schneider Electric devices
• Implement network-based intrusion detection rules to identify potential MITM attack patterns
• Deploy file integrity monitoring on affected systems to detect unauthorized file access
• Analyze authentication logs for unusual login patterns that may indicate privilege escalation attempts

Monitoring Recommendations

• Enable verbose logging on all Schneider Electric devices to capture detailed access records
• Implement network segmentation monitoring to detect unauthorized lateral movement
• Configure alerts for any access attempts to restricted directories or configuration files
• Establish baseline network behavior for industrial control systems and alert on deviations

How to Mitigate CVE-2025-2222

Immediate Actions Required

• Review and apply security updates from Schneider Electric as outlined in Security Notice SEVD-2025-098-01
• Implement network segmentation to isolate affected Schneider Electric devices from untrusted networks
• Deploy intrusion detection and prevention systems to monitor for MITM attack indicators
• Audit file permissions on affected systems to restrict access to sensitive directories

Patch Information

Schneider Electric has released a security notice (SEVD-2025-098-01) addressing this vulnerability. Administrators should review the official Schneider Electric Security Notice for detailed patch information, affected product versions, and specific remediation guidance.

Workarounds

• Implement strict network access controls to limit which systems can communicate with affected devices
• Deploy TLS inspection and certificate pinning to reduce the effectiveness of MITM attacks
• Use VPN tunnels for all communications with affected industrial control systems
• Disable unnecessary services and close unused network ports on affected devices
