The ip package through 2.0.1 for Node.js might allow Server-Side Request Forgery (SSRF) because some IP addresses (such as 127.1, 01200034567, 012.1.2.3, 000:0:0000::01, and ::fFFf:127.0.0.1) are improperly categorized as globally routable via isPublic. This issue exists because of an incomplete fix for CVE-2023-42282.
Organizations should be aware of the implications of this vulnerability. The CVSS score of 8.1 classifies it as high severity, indicating a significant risk to systems utilizing this package. The potential for exploitation exists, and the vulnerability is already known to be actively exploitable.
Given the exploitability and the nature of SSRF attacks, organizations should prioritize remediation efforts to mitigate this issue. Failure to do so could lead to unauthorized access and data breaches.
The urgency for defenders is high, and organizations should implement patches as soon as they are available, as this vulnerability may lead to serious security incidents.
Vulnerability Details
The ip package through 2.0.1 for Node.js allows for SSRF due to improper categorization of certain IP addresses as globally routable. The CVSS 3.1 score is 8.1, indicating a high severity level. The affected package is the ip library used in Node.js applications.
Published on May 27, 2024, the issue represents a CWE classification of CWE-918 (Server-Side Request Forgery) and CWE-941 (Incorrect Exception Handling).
Technical Analysis
The root cause of this vulnerability stems from the failure to correctly classify certain malformed IP addresses. Attackers can leverage this misclassification to send requests from a vulnerable server, potentially exposing sensitive information or allowing access to internal resources.
The attack vector is network-based, requiring low-level privileges to exploit, with no user interaction necessary. The complexity of the attack is classified as high. The vulnerability impacts confidentiality, integrity, and availability, making it critical for organizations to address.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to sensitive data, which could lead to data breaches and regulatory penalties. The potential blast radius is significant as this vulnerability affects all applications utilizing the ip package.
Given the exploitability and the high CVSS score, organizations should assess their exposure and prioritize this vulnerability in their patch cycles.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | Yes |
Public PoC | Yes |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The vulnerability affects all versions of the ip package prior to 2.0.1. Organizations using this package should verify their versions and plan for updates.
Mitigation & Remediation
Organizations should implement the latest patches for the ip package to address this vulnerability. If immediate patching is not possible, consider applying workarounds such as restricting the use of the ip package in sensitive applications.
For further guidance on securing applications, organizations can refer to resources on penetration testing methodology and effective vulnerability management.
Detection Guidance
To detect potential exploitation of this vulnerability, organizations should monitor logs for unusual outbound requests, especially from internal servers. Behavioral anomalies that may indicate SSRF should be investigated.
AppSecure Threat Intelligence Insight
The long-term significance of CVE-2024-29415 highlights the need for robust input validation within network-facing applications. This vulnerability underscores the importance of properly categorizing IP addresses to prevent SSRF attacks.
Security teams should consider adopting comprehensive security testing practices to identify similar weaknesses in their applications. Engaging in vulnerability management programs can enhance overall security posture.
Additionally, organizations should consider utilizing API security testing to ensure that all interfaces are secure against potential SSRF vulnerabilities.
As a strategic defensive takeaway, organizations must remain vigilant and regularly update their dependencies to mitigate risks associated with known vulnerabilities.
