CVE-2023-42282
Description
A vulnerability was found in the NPM IP Package. This flaw allows an attacker to perform arbitrary code execution and obtain sensitive information via the isPublic() function by inducing a Server-Side Request Forgery (SSRF) attack and obtaining access to normally inaccessible resources.
Statement
It appears that npm does not utilize the bundled code therefore Red Hat Enterprise Linux is not affected by this vulnerability.
While the vulnerability in the NPM IP Package presents a significant security concern, it's categorized as important rather than critical due to several factors. Firstly, the misclassification of the private IP address 0x7f.1 as public by the isPublic() function does not directly lead to remote code execution or unauthorized access to critical systems. Instead, it facilitates SSRF attacks, which typically require additional conditions to fully exploit, such as the ability to influence server-side requests and responses. Additionally, the impact of SSRF attacks can vary depending on the specific environment and configuration of the affected system. While SSRF attacks can potentially lead to data exposure, service disruption, or lateral movement within a network, their severity is often mitigated by factors such as network segmentation, access controls, and the availability of sensitive resources.
Red Hat Developer Hub contains a fix in 1.1-91 version.
Mitigation
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Application Data
Integrity
Technical Impact: Execute Unauthorized Code or Commands
Access Control
Technical Impact: Bypass Protection Mechanism
By providing URLs to unexpected hosts or ports, attackers can make it appear that the server is sending the request, possibly bypassing access controls such as firewalls that prevent the attackers from accessing the URLs directly. The server can be used as a proxy to conduct port scanning of hosts in internal networks, use other URLs such as that can access documents on the system (using file://), or use other protocols such as gopher:// or tftp://, which may provide greater control over the contents of requests.
