CVE-2023-28706: Critical Vulnerability in Apache Airflow Hive Provider

CVE-2023-28706 is a critical vulnerability classified as an improper control of generation of code, commonly known as a code injection vulnerability, in the Apache Airflow Hive Provider. This vulnerability affects all versions of the Apache Airflow Hive Provider prior to 6.0.0. The CVSS score for this vulnerability stands at 9.8, indicating a critical severity level.

The implications of this vulnerability are significant. Attackers may leverage this vulnerability to execute arbitrary code, leading to severe impacts on confidentiality, integrity, and availability. Organizations using affected versions of the Apache Airflow Hive Provider are at risk of unauthorized access and potential data breaches.

Currently, there is no known exploit publicly available for this vulnerability, but organizations should not consider themselves safe. The absence of known exploitation does not diminish the urgency for remediation. Organizations should prioritize patching immediately to close this vulnerability.

Given the critical nature of this vulnerability, it is essential for organizations to take immediate action to safeguard their systems. Regular updates and security practices should be enforced to prevent similar vulnerabilities in the future.

Vulnerability Details

This vulnerability allows attackers to execute arbitrary code through improper control of the generation of code within the Apache Airflow Hive Provider. The official CVE description highlights that this issue affects the provider in all versions before 6.0.0. The CVSS score of 9.8 categorizes this vulnerability as critical, reflecting its potential for severe impact.

The vulnerability is classified under CWE-94, which pertains to code injection vulnerabilities. This indicates a flaw in the way input is handled by the application, allowing malicious users to manipulate the execution of code.

The vulnerability was published on April 7, 2023, and remains relevant as organizations continue to utilize versions of Apache Airflow Hive Provider that are vulnerable.

Technical Analysis

The root cause of this vulnerability lies in the improper validation of user input, which can lead to the execution of arbitrary code on the server. The attack vector for this vulnerability is network-based, meaning that an attacker can exploit it remotely without physical access to the system.

The attack complexity is classified as low, indicating that exploiting this vulnerability does not require significant skill or resources. Importantly, no privileges are required to execute the exploit, and no user interaction is necessary, making this vulnerability particularly dangerous.

The confidentiality, integrity, and availability impacts are all rated as high, underscoring the critical nature of this vulnerability. An attacker could potentially gain unauthorized access to sensitive data, alter it, or disrupt service availability.

Risk & Impact Analysis

The real-world risk associated with CVE-2023-28706 is substantial. Organizations using the affected version of the Apache Airflow Hive Provider may face severe data breaches, loss of integrity of their systems, and disruptions in service availability. The blast radius of such an attack could extend to sensitive data exposure, affecting not only the organization but also its clients and partners.

Given the critical CVSS score of 9.8, organizations must address this vulnerability in their priority patch cycle. The urgency for remediation is underscored by the lack of public exploits, as attackers may seek to develop their own methods of exploitation.

Organizations should conduct thorough assessments of their systems to determine their exposure to this vulnerability and implement necessary updates promptly to mitigate risks.

Exploitation Status

Affected Versions

The vulnerability affects all versions of Apache Airflow Hive Provider prior to 6.0.0. Organizations running these versions should take immediate action to upgrade to secure versions.

Mitigation & Remediation

Organizations must patch the Apache Airflow Hive Provider to version 6.0.0 or later to remediate this vulnerability. If immediate patching is not possible, organizations should implement workarounds that restrict user input and minimize the risk of code injection.

Further, organizations should engage in continuous monitoring of their systems and apply configuration hardening practices to prevent exploitation of similar vulnerabilities in the future. Regular security assessments, such as penetration testing, can help identify and mitigate potential risks.

Detection Guidance

Security teams should monitor logs for any unusual activity that could indicate attempts to exploit this vulnerability. Key indicators include unexpected code execution, modifications to scripts, or unauthorized access attempts.

Behavioral anomalies in the application should also be closely observed, as they may signify exploitation attempts. Regular audits and system checks can assist in identifying vulnerabilities before they can be exploited.

AppSecure Threat Intelligence Insight
