CVE-2025-5162: H3C SecCenter SMP RCE Vulnerability

CVE-2025-5162 Overview

A critical unrestricted file upload vulnerability has been discovered in H3C SecCenter SMP-E1114P02 up to version 20250513. This security flaw affects the /safeEvent/importFile/ endpoint, where improper handling of the logGeneralFile and logGeneralFile_2 parameters allows attackers to upload arbitrary files to the system without proper validation or restrictions.

The vulnerability stems from missing file type validation and access control mechanisms (CWE-434: Unrestricted Upload of File with Dangerous Type, CWE-284: Improper Access Control). Exploitation can be performed remotely by authenticated attackers, potentially leading to remote code execution, system compromise, or further lateral movement within the network infrastructure.

Critical Impact

Authenticated attackers can remotely upload malicious files to H3C SecCenter SMP-E1114P02 systems, potentially achieving remote code execution and full system compromise on security management infrastructure.

Technical Details for CVE-2025-5162

Vulnerability Analysis

This vulnerability represents a dangerous combination of improper access control (CWE-284) and unrestricted file upload (CWE-434) in the H3C SecCenter security management platform. The affected endpoint /safeEvent/importFile/ is designed to handle event log imports but fails to properly validate uploaded file content, type, or extension.

The H3C SecCenter SMP-E1114P02 is a security management platform used for centralized security event monitoring and management. The vulnerable functionality allows authenticated users to import log files, but the lack of proper input validation creates a pathway for attackers to upload executable scripts, web shells, or other malicious payloads.

The attack can be launched remotely over the network, requiring only low-privilege authentication. Once malicious files are uploaded, attackers may achieve code execution depending on the server configuration and the location where uploaded files are stored.

Root Cause

The root cause of this vulnerability lies in insufficient input validation within the file import functionality. The application fails to implement several critical security controls:

1. Missing file type validation: The application does not verify that uploaded files match expected log file formats
2. Improper file extension checking: No validation ensures uploaded files have safe extensions
3. Lack of content inspection: File contents are not scanned for malicious payloads
4. Improper access control: The endpoint may not adequately restrict which users can perform file uploads

The logGeneralFile and logGeneralFile_2 parameters accept arbitrary file data without sanitization, allowing attackers to bypass intended functionality restrictions.

Attack Vector

The attack leverages the network-accessible /safeEvent/importFile/ endpoint to upload malicious files. An attacker with valid credentials (low-privilege authentication required) can craft a malicious HTTP POST request to the vulnerable endpoint, manipulating the logGeneralFile or logGeneralFile_2 parameters to include dangerous file content.

Depending on the server-side configuration and file storage location, uploaded files could be directly accessible via the web server, enabling remote code execution through web shells or similar malicious scripts. The public disclosure of exploit details increases the risk of active exploitation attempts.

For technical details about this vulnerability, refer to the VulDB entry #310250 and the associated technical documentation on Flowus.

Detection Methods for CVE-2025-5162

Indicators of Compromise

• Unusual HTTP POST requests to /safeEvent/importFile/ with non-standard file extensions or content types
• Presence of unexpected files in upload directories, particularly files with executable extensions (.php, .jsp, .aspx, .sh)
• Web server logs showing requests to newly created files in import directories
• Authentication events followed immediately by file upload activity to the vulnerable endpoint

Detection Strategies

• Monitor HTTP traffic for POST requests to /safeEvent/importFile/ containing suspicious file types or unusual logGeneralFile parameter values
• Implement file integrity monitoring on directories associated with the import functionality
• Deploy web application firewall (WAF) rules to detect and block file upload attempts with dangerous extensions
• Review access logs for patterns indicating reconnaissance or exploitation attempts against the vulnerable endpoint

Monitoring Recommendations

• Enable detailed logging for all file upload operations on H3C SecCenter systems
• Configure alerts for any new file creation in web-accessible directories associated with import functions
• Monitor for outbound connections from the SecCenter system that may indicate post-exploitation activity
• Implement network segmentation monitoring to detect lateral movement from compromised security infrastructure

How to Mitigate CVE-2025-5162

Immediate Actions Required

• Restrict network access to H3C SecCenter SMP-E1114P02 management interfaces using firewall rules or network segmentation
• Review and audit user accounts with access to the import functionality, removing unnecessary privileges
• Implement additional authentication controls or access restrictions for the /safeEvent/importFile/ endpoint
• Monitor the system for signs of exploitation and conduct a forensic review of recently uploaded files

Patch Information

The vendor (H3C) was contacted early about this disclosure but did not respond. As of the last NVD update on 2025-06-03, no official patch has been made available. Organizations should monitor VulDB and H3C's official security advisories for patch availability.

Until an official patch is released, implementing compensating controls and network-level restrictions is critical to reduce exposure.

Workarounds

• Apply network-level access controls to restrict access to the SecCenter management interface to trusted IP addresses only
• Implement a web application firewall (WAF) with rules to block file uploads containing dangerous content or extensions
• Disable or restrict the /safeEvent/importFile/ functionality if not operationally required
• Place the H3C SecCenter system behind a VPN to limit exposure to authenticated and authorized users only

# Example: Restrict access to SecCenter using iptables
# Allow only trusted management subnet
iptables -A INPUT -p tcp --dport 443 -s 10.0.100.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 443 -j DROP

# Example: Block specific endpoint patterns (requires reverse proxy)
# Add to nginx or Apache configuration
# location /safeEvent/importFile/ {
#     deny all;
# }
