📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system compromise allowing attackers to execute arbitrary commands as the web server user, potentially leading to privilege escalation, data theft, or installation of persistent backdoors.

🟠

Likely Case

Remote code execution leading to unauthorized access, data exfiltration, or use of the server as part of a botnet.

🟢

If Mitigated

Limited impact if proper input validation and command sanitization are implemented, potentially resulting in failed exploitation attempts.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

Exploitation requires access to the vulnerable timezone parameter. The vulnerability is documented in security advisories but no public proof-of-concept has been released.

🛠️ Fix & Mitigation

🔧 Temporary Workarounds

Input Validation Filter

all

Implement strict input validation for the timezone parameter to only accept expected timezone values

Web Application Firewall Rule

all

Deploy WAF rules to block suspicious patterns in timezone parameter values

🧯 If You Can't Patch

  • Implement strict input validation to only allow whitelisted timezone values
  • Disable or restrict access to the vulnerable functionality if not required

🔍 How to Verify

Check if Vulnerable:

Check OpenPanel version: If version is exactly 0.3.4, the system is vulnerable.

Check Version:

openpanel --version

Verify Fix Applied:

Verify OpenPanel version is 0.3.5 or later and test timezone functionality with malicious input to ensure it's properly sanitized.

📡 Detection & Monitoring

Log Indicators:

  • Unusual timezone parameter values containing shell metacharacters
  • Multiple failed attempts with suspicious timezone values
  • Commands executed from web server process that don't match normal operations

Network Indicators:

  • HTTP requests with unusual timezone parameter values containing shell commands
  • Outbound connections from web server to unexpected destinations

SIEM Query:

source="openpanel" AND (timezone="*;*" OR timezone="*|*" OR timezone="*`*" OR timezone="*$(*" OR timezone="*&*" OR timezone="*>*" OR timezone="*<*")
