CVE-2023-42282 is a critical vulnerability affecting the fedorindutny ip package for Node.js, specifically versions prior to 1.1.9. This vulnerability allows Server-Side Request Forgery (SSRF) due to improper categorization of certain IP addresses, such as 0x7f.1, as globally routable via the isPublic function. The exploitation of this vulnerability can lead to significant unauthorized access to sensitive information within the affected systems.
With a CVSS score of 9.8, this vulnerability is classified as critical, indicating that attackers can leverage this weakness with low complexity and no privileges required. Organizations utilizing the affected versions of the ip package must act swiftly to mitigate the risk associated with this vulnerability.
Risk to organizations includes potential unauthorized access to internal resources and sensitive data exposure. Given the severity and exploitability of this vulnerability, organizations should prioritize patching immediately.
As of now, there are no confirmed public exploits or available proof of concept (PoC) for CVE-2023-42282, but the critical nature of the vulnerability cannot be understated. Organizations must ensure they are on the latest patched version to prevent any potential exploitation.
Immediate action is required to address this critical issue, as attackers may attempt to exploit this vulnerability in the wild. Organizations should conduct a thorough assessment of their use of the ip package and upgrade to the fixed version as soon as possible.
Vulnerability Details
The ip package before version 1.1.9 for Node.js is vulnerable due to improper categorization of certain IP addresses that may lead to SSRF. This vulnerability has been classified under CWE-918, indicating a failure to control IP addresses that could be exploited. The CVSS base score of 9.8 signals a critical vulnerability with a high potential impact on confidentiality, integrity, and availability.
Technical Analysis
This vulnerability allows attackers to send crafted requests that could be improperly routed to internal services. The root cause lies in the failure of the isPublic function to adequately categorize certain IP addresses. The attack vector is network-based, requiring no privileges or user interaction to execute the attack, and the complexity is low.
The potential impacts are severe, affecting confidentiality, integrity, and availability. This vulnerability poses a significant risk to organizations that depend on the ip package to manage IP addresses in their applications.
Risk & Impact Analysis
Real-world deployment risks include the potential for unauthorized access to internal services and sensitive data leakage. Organizations that rely on the ip package for network operations are particularly vulnerable to attacks that exploit SSRF. The blast radius is significant, as an attacker could leverage this vulnerability to access other parts of the network that are otherwise protected.
Urgency assessment indicates that organizations should address this vulnerability in their priority patch cycle due to its critical CVSS score and potential for exploitation.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The ip package versions prior to 1.1.9 are affected. Organizations should update to the latest version to mitigate the risk associated with this vulnerability.
Mitigation & Remediation
Organizations should prioritize patching by upgrading to the latest version of the ip package. If immediate patching is not possible, consider implementing network controls to restrict access to internal services and monitoring for unusual request patterns. For further guidance on security measures, organizations can refer to resources such as penetration testing services that can help identify vulnerabilities in their applications.
Detection Guidance
Security teams should monitor logs for unusual outbound requests, especially those targeting internal services. Behavioral anomalies and any unexpected changes to the isPublic function should be flagged for further investigation. Additionally, network signatures for known malicious patterns should be established.
