CVE-2024-28397 represents a medium-severity vulnerability found in the js2py library. This issue, affecting versions up to v0.74, allows attackers to execute arbitrary code via a crafted API call. With a CVSS score of 5.3, this vulnerability poses a significant risk, particularly in environments where js2py is utilized for executing JavaScript within Python. The nature of the vulnerability suggests that an attacker with local access can exploit this flaw, which emphasizes the need for immediate attention from security practitioners.
Risk to organizations includes potential unauthorized code execution, which could lead to further exploitation of the system. Attackers may leverage this vulnerability to gain access to sensitive data or disrupt services. The urgency for defenders is clear: organizations should address this vulnerability in their priority patch cycle to mitigate risks associated with arbitrary code execution.
The vulnerability was published on June 20, 2024, and has been classified under CWE-94, which pertains to code injection issues. This classification highlights the vulnerability's severity and the importance of addressing it promptly. Given the current state of security vulnerabilities and the prevalence of exploitation in similar scenarios, security teams must remain vigilant.
With known exploits already available, organizations should prioritize patching immediately to prevent potential attacks. The existence of public proof-of-concept code on platforms like GitHub further underscores the need for prompt remediation efforts.
Vulnerability Details
This vulnerability allows attackers to execute arbitrary code via a crafted API call by leveraging the js2py.disable_pyimport() component. The severity is classified as medium, with a CVSS score of 5.3. The attack vector is local, requiring low privilege levels, and does not necessitate user interaction. The confidentiality, integrity, and availability impacts are all rated as low.
Technical Analysis
The root cause of CVE-2024-28397 lies in improper validation within the js2py library, specifically in the js2py.disable_pyimport() function. This flaw allows crafted JavaScript code to exploit the library's sandboxing mechanisms, ultimately leading to arbitrary code execution. The attack vector is local, meaning attackers need access to the environment running js2py. The attack complexity is low, and the privileges required are also low, making it easier for attackers to exploit this vulnerability. User interaction is not required to carry out the attack.
The impacts on confidentiality, integrity, and availability are all low, but the potential for an attacker to execute arbitrary code poses significant risks. Organizations must be aware of the implications and prepare for possible exploitation scenarios.
Risk & Impact Analysis
Real-world deployment risk is high due to the potential for arbitrary code execution, which could lead to unauthorized access and data breaches. Organizations using js2py must recognize the potential blast radius of this vulnerability, especially in production environments where sensitive operations are performed. The urgency assessment, based on the CVSS score of 5.3, suggests organizations should address this vulnerability in their priority patch cycle.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | Yes |
Public PoC | Yes |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
All versions of js2py prior to v0.75 are affected by this vulnerability. It is crucial for organizations utilizing this library to review their implementations and apply necessary updates.
Mitigation & Remediation
To mitigate CVE-2024-28397, organizations should upgrade js2py to version 0.75 or later. If immediate patching is not feasible, consider implementing additional security controls to limit access to affected components. Regularly monitor for any unusual activity that may indicate exploitation attempts. Furthermore, organizations should conduct regular security assessments, such as penetration testing, to validate the effectiveness of security measures.
Detection Guidance
Organizations should monitor logs for indicators of exploitation, such as unusual API calls or unexpected code execution patterns. Behavioral anomalies in applications using js2py can signal potential exploitation attempts. Additionally, network signatures that identify unauthorized access attempts should be established and monitored.
