CVE-2023-26219

7.4 HIGH

📋 TL;DR

This vulnerability in TIBCO Hawk components allows attackers with access to log files to extract credentials used for EMS server authentication. Affected organizations are those running vulnerable versions of TIBCO Hawk, Hawk Distribution for Silver Fabric, Operational Intelligence Hawk RedTail, or Runtime Agent.

💻 Affected Systems

Products:
  • TIBCO Hawk
  • TIBCO Hawk Distribution for TIBCO Silver Fabric
  • TIBCO Operational Intelligence Hawk RedTail
  • TIBCO Runtime Agent
Versions: TIBCO Hawk: ≤6.2.2, Hawk Distribution for Silver Fabric: ≤6.2.2, Hawk RedTail: ≤7.2.1, Runtime Agent: ≤5.12.2
Operating Systems: All supported OS for these products
Default Config Vulnerable: ⚠️ Yes
Notes: Vulnerability exists when Hawk Console and Agent logs contain EMS credentials; requires attacker access to these logs.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Attackers gain EMS server credentials, potentially leading to unauthorized access, data exfiltration, or disruption of messaging services.

🟠

Likely Case

Internal attackers or compromised accounts access logs to steal credentials for lateral movement within the network.

🟢

If Mitigated

With proper log access controls and credential rotation, impact is limited to credential exposure without actual compromise.

🌐 Internet-Facing: LOW - Exploitation requires access to log files, typically not internet-exposed.
🏢 Internal Only: HIGH - Internal attackers or compromised accounts can access logs to extract credentials for further attacks.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: LOW - Requires only read access to log files containing credentials.

Exploitation is straightforward if log files are accessible; no special tools needed beyond file access.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: TIBCO Hawk: 6.2.3+, Hawk Distribution for Silver Fabric: 6.2.3+, Hawk RedTail: 7.2.2+, Runtime Agent: 5.12.3+

Vendor Advisory: https://www.tibco.com/services/support/advisories

Restart Required: Yes

Instructions:

1. Download patches from TIBCO support portal. 2. Apply patches to affected components. 3. Restart Hawk Console and Agent services. 4. Verify EMS connectivity post-update.

🔧 Temporary Workarounds

Restrict log file access

linux

Set strict file permissions on Hawk Console and Agent log directories to prevent unauthorized access.

chmod 600 /path/to/hawk/logs/*
chown hawkuser:hawkgroup /path/to/hawk/logs/

Rotate EMS credentials

all

Change EMS server credentials used by Hawk components to invalidate any potentially exposed credentials.

🧯 If You Can't Patch

  • Implement strict access controls on log directories (read-only for authorized users only).
  • Monitor log access attempts and implement credential rotation policies for EMS accounts.

🔍 How to Verify

Check if Vulnerable:

Check version numbers of installed TIBCO Hawk components against affected versions list.

Check Version:

Consult TIBCO documentation for component-specific version check commands (varies by product).

Verify Fix Applied:

Verify installed versions are at or above patched versions and test EMS connectivity.

📡 Detection & Monitoring

Log Indicators:

  • Unauthorized access attempts to Hawk log files
  • Failed authentication attempts to EMS servers using potentially exposed credentials

Network Indicators:

  • Unusual EMS server connections from unexpected sources

SIEM Query:

source="hawk_logs" AND (event="access_denied" OR event="file_read") OR destination="ems_server" AND auth_failure
