CVE-2024-38461

7.5 HIGH

📋 TL;DR

This vulnerability in iRODS allows attackers to cause the irodsServerMonPerf component to process a path that isn't a directory, potentially leading to denial of service or other unexpected behavior. It affects iRODS installations before version 4.3.2. Organizations using vulnerable iRODS versions for data management are at risk.

💻 Affected Systems

Products:
  • iRODS
Versions: All versions before 4.3.2
Operating Systems: Linux, Unix-like systems
Default Config Vulnerable: ⚠️ Yes
Notes: Affects irodsServerMonPerf component specifically; requires this component to be enabled and accessible.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Remote code execution or complete system compromise through path traversal leading to arbitrary file access or service disruption.

🟠

Likely Case

Denial of service causing iRODS service interruption or performance degradation.

🟢

If Mitigated

Minimal impact with proper network segmentation and access controls limiting exposure.

🌐 Internet-Facing: MEDIUM - iRODS services exposed to internet could be targeted, but exploitation requires specific conditions.
🏢 Internal Only: MEDIUM - Internal attackers or compromised systems could exploit this to disrupt data management services.

🎯 Exploit Status

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

Exploitation requires access to the irodsServerMonPerf interface and ability to supply malformed paths.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 4.3.2

Vendor Advisory: https://irods.org/2024/05/irods-4-3-2-is-released

Restart Required: Yes

Instructions:

1. Backup iRODS configuration and data. 2. Download iRODS 4.3.2 from official repository. 3. Stop iRODS services. 4. Install/upgrade to version 4.3.2. 5. Restart iRODS services. 6. Verify functionality.

🔧 Temporary Workarounds

Disable irodsServerMonPerf

linux

Temporarily disable the vulnerable component until patching is possible

sudo systemctl stop irods-server-monperf
sudo systemctl disable irods-server-monperf

Restrict Network Access

linux

Limit network access to iRODS services using firewall rules

sudo iptables -A INPUT -p tcp --dport 1247 -s trusted_network -j ACCEPT
sudo iptables -A INPUT -p tcp --dport 1247 -j DROP

🧯 If You Can't Patch

  • Implement strict network segmentation to isolate iRODS services from untrusted networks
  • Apply principle of least privilege to iRODS service accounts and file system permissions

🔍 How to Verify

Check if Vulnerable:

Check iRODS version: 'irods_version' command or examine package version. If version is below 4.3.2, system is vulnerable.

Check Version:

irods_version

Verify Fix Applied:

After upgrade, run 'irods_version' to confirm version 4.3.2 or higher is installed.

📡 Detection & Monitoring

Log Indicators:

  • Error messages related to irodsServerMonPerf path processing
  • Unexpected service restarts or crashes in iRODS logs

Network Indicators:

  • Unusual traffic patterns to iRODS monitoring ports
  • Multiple failed path requests to iRODS services

SIEM Query:

source="irods.log" AND ("irodsServerMonPerf" OR "path error" OR "not a directory")
