CVE-2022-28810 is classified as a medium-severity vulnerability affecting Zoho ManageEngine ADSelfService Plus prior to build 6122. This vulnerability allows a remote authenticated administrator to execute arbitrary operating system commands as SYSTEM through the policy custom script feature. The exploitation of this vulnerability is made easier due to the presence of a default administrator password, enabling attackers to abuse the feature with minimal effort. Furthermore, a remote and partially authenticated attacker may inject arbitrary commands into the custom script, exploiting an unsanitized password field.
The CVSS score for this vulnerability is 6.8, indicating a medium level of severity. This score reflects the potential impact on confidentiality, integrity, and availability, all rated as high. The attack vector is network-based, requiring low complexity and high privileges to exploit, alongside some user interaction. Organizations utilizing affected versions of Zoho ManageEngine ADSelfService Plus should take immediate action to assess their exposure to this vulnerability.
Given the nature of this vulnerability, risk to organizations includes unauthorized execution of commands that could lead to further exploitation of the system, data breaches, or service disruption. Organizations should prioritize patching immediately to mitigate these risks. It is essential to review configurations and ensure that default credentials are changed to prevent exploitation.
Currently, no public exploit has been confirmed for CVE-2022-28810, but it has been included in the CISA Known Exploited Vulnerabilities Catalog as of March 2023, indicating recognized risk. Organizations should address this vulnerability in their priority patch cycle to ensure the security of their systems.
Vulnerability Details
The vulnerability allows for remote command execution in Zoho ManageEngine ADSelfService Plus due to improper validation of user input in the custom script feature. The CVSS 3.1 score of 6.8 suggests that while the vulnerability is significant, it requires certain conditions, including authenticated access, to exploit.
The affected product is Zoho ManageEngine ADSelfService Plus, specifically versions prior to build 6122. The vulnerability was disclosed on April 18, 2022, and falls under several Common Weakness Enumeration (CWE) categories, including CWE-78 (OS Command Injection) and CWE-798 (Use of Hard-coded Credentials).
Technical Analysis
The root cause of CVE-2022-28810 is the insufficient validation of user input in the custom script feature, which allows for OS command execution. The attack vector is remote, with a low complexity level, meaning that the exploitation does not require advanced skills. High privileges are necessary to execute the commands, and user interaction is required for some aspects of the attack.
Exploitation can lead to significant impacts, including high confidentiality, integrity, and availability impacts. This vulnerability allows attackers to execute commands with SYSTEM privileges, which could lead to unauthorized access to sensitive information or disruption of services.
Risk & Impact Analysis
Organizations utilizing Zoho ManageEngine ADSelfService Plus should assess their risk exposure concerning CVE-2022-28810. The potential for unauthorized command execution poses a considerable threat, particularly in environments where sensitive data is managed. The urgency is elevated due to the inclusion in the CISA Known Exploited Vulnerabilities Catalog.
The blast radius of exploitation is significant, as successful attacks could compromise entire systems, leading to data breaches or service disruptions across multiple areas of the organization. Organizations should address this vulnerability as part of their immediate patching efforts.
Given the CVSS score of 6.8 and the active exploitation status, it is critical for organizations to prioritize remediation within their security operations. This vulnerability should be treated as a top priority to mitigate potential impacts.
