A critical vulnerability in Netflix's open-source Genie job orchestration engine poses severe risks to systems running affected versions. Designated as CVE-2024-4701, this bug scores a near-maximum 9.9 on the CVSS scale, underscoring its potential impact.
This Threatfeed meticulously dissects the vulnerability, its exploitation mechanisms, and the mitigation strategies, adhering strictly to industry standards and best practices.
The CVE-2024-4701 vulnerability affects Genie OSS versions prior to 4.3.18. Genie facilitates orchestration and monitoring of big data jobs across frameworks like Hadoop and Spark.
The vulnerability arises from the way Genie handles file uploads via its API, leading to a path traversal attack.
Path traversal vulnerabilities allow attackers to manipulate file paths. In the context of CVE-2024-4701, the attacker can upload files to unintended locations on the server. The flaw stems from Genie’s API, which improperly sanitizes user-supplied file names during the file upload process.
def handle_file_upload(file, filename):
safe_path = os.path.join(UPLOAD_DIRECTORY, filename)
with open(safe_path, 'wb') as f:
f.write(file.read())In the above snippet, if `filename` includes path traversal characters (`../`), it can lead to files being saved outside the intended directory.
By exploiting this vulnerability, an attacker can execute arbitrary code on the server. This is due to the ability to upload malicious scripts to executable directories. The lack of proper input validation and sanitization in the file upload handler makes this possible.
CVE-2024-4701’s CVSS score of 9.9 reflects its high impact and ease of exploitation. No special privileges or user interactions are required to exploit this vulnerability. This makes it particularly dangerous for organizations relying on Genie for their big data operations.
A successful attack can lead to severe consequences:
Netflix has been using Genie internally to manage thousands of Hadoop jobs daily. The company’s large-scale environment, handling petabytes of data, underscores the critical nature of this vulnerability. If exploited, attackers could disrupt Netflix’s data processing workflows and access sensitive operational data.
Organizations using affected versions of Genie OSS should upgrade to version 4.3.18 immediately. This version includes patches that address the path traversal vulnerability.
def secure_filename(filename):
return os.path.basename(filename)
def handle_secure_file_upload(file, filename):
safe_filename = secure_filename(filename)
safe_path = os.path.join(UPLOAD_DIRECTORY, safe_filename)
with open(safe_path, 'wb') as f:
f.write(file.read())Path traversal vulnerabilities are common and pose significant risks. They allow attackers to access restricted directories and files, leading to data breaches and system compromises.
The FBI’s Internet Crime Complaint Center (IC3) has highlighted several high-profile path traversal incidents. For example, CVE-2024-1708 in ConnectWise ScreenConnect and CVE-2024-20345 in Cisco AppDynamics Controller were exploited to deliver ransomware and compromise critical infrastructure.
Splunk disclosed CVE-2026-20253, a critical pre-auth RCE flaw in Splunk Enterprise (CVSS 9.8) from insecure MongoDB defaults. Patches released; upgrade to 9.1.8, 9.2.5, or 9.3.2.
