CVE-2022-38211 is a high-severity vulnerability affecting Esri Portal for ArcGIS versions 10.9.1 and below. This vulnerability allows protections against potential Server-Side Request Forgery (SSRF) vulnerabilities to be bypassed. A remote, unauthenticated attacker could leverage this flaw to forge requests to arbitrary URLs from the system. The potential consequences include network enumeration and unauthorized access to hosts within the network perimeter. Given the nature of this vulnerability, organizations using affected versions should prioritize addressing it in their patch management cycles.
The CVSS score for this vulnerability is 7.5, categorizing it as high severity. This score reflects the ease of exploitation, which is considered low due to the lack of required privileges and user interaction. However, the high confidentiality impact indicates significant risk to sensitive data.
Organizations are urged to assess their exposure to CVE-2022-38211 and take immediate action to patch affected systems. The risk to organizations includes potential data breaches and unauthorized access to internal resources, making swift remediation critical.
As of now, there are no publicly available exploits for CVE-2022-38211, but the impact of successful exploitation could be severe. Therefore, organizations should not underestimate the importance of addressing this vulnerability quickly.
Vulnerability Details
The vulnerability is defined by the inability of Esri Portal for ArcGIS to adequately protect against SSRF attacks. Specifically, protections in place were not fully honored, which allows attackers to send crafted requests to internal systems. The CVSS vector for this vulnerability is CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N, which highlights the network attack vector and low attack complexity.
This vulnerability falls under CWE-918, indicating a lack of proper validation. The potential for unauthorized access within the network makes it imperative for affected users to understand the risk and take action.
The vulnerability was published on December 29, 2022, and has since been classified as modified, indicating changes or updates in its status or understanding.
Technical Analysis
The root cause of CVE-2022-38211 is primarily attributed to insufficient validation of user input that leads to SSRF vulnerabilities. Attackers can exploit this flaw to send requests from the vulnerable server to any internal resource, which could include databases, internal APIs, or other services that are not meant to be exposed to the internet.
The attack vector is categorized as network-based, where attackers can initiate requests over the network without requiring any prior access to the system. The attack complexity is low, as no special conditions or prerequisites are needed for the attack to succeed.
This vulnerability requires no privileges to exploit, and user interaction is also not necessary. The impact on confidentiality is high, given the potential for sensitive data exposure, while integrity and availability impacts are not applicable in this scenario.
Risk & Impact Analysis
The risk associated with CVE-2022-38211 is significant, particularly for organizations that rely on Esri Portal for ArcGIS for managing geographic information system (GIS) data. Successful exploitation could lead to unauthorized access to sensitive internal systems, which may contain critical data and resources.
Organizations not addressing this vulnerability may face severe consequences, including data breaches, compliance issues, and damage to their reputation. The potential for network enumeration further increases the risk, as attackers could gain insights into the internal infrastructure.
Given the CVSS score of 7.5, organizations should prioritize patching this vulnerability immediately. Failure to do so may expose them to significant risks and potential exploitation.
