CVE-2025-10020 is an authenticated command injection vulnerability identified in Zohocorp's ManageEngine ADManager Plus product, specifically affecting versions before 8024. The vulnerability resides in the Custom Script component, which improperly neutralizes special characters used in command execution, classified under CWE-77. This flaw allows an attacker with low-level privileges to inject and execute arbitrary system commands remotely without requiring user interaction. The vulnerability is remotely exploitable over the network (AV:N), requires low attack complexity (AC:H) but only low privileges (PR:L), and does not require user interaction (UI:N). The scope is changed (S:C), meaning the vulnerability can affect resources beyond the initially vulnerable component. The impact is severe, affecting confidentiality, integrity, and availability (C:H/I:H/A:H), as attackers can execute arbitrary commands leading to potential full system compromise, data theft, or service disruption. Although no known exploits are currently reported in the wild, the high CVSS score of 8.5 indicates a serious threat. The vulnerability highlights the risks associated with improper input validation in administrative tools that interact with critical infrastructure like Active Directory. Since ManageEngine ADManager Plus is widely used for Active Directory management in enterprises, this vulnerability could be leveraged for lateral movement and privilege escalation within corporate networks. The lack of an available patch at the time of disclosure necessitates immediate mitigation efforts by organizations to reduce exposure.

The impact of CVE-2025-10020 is significant for organizations worldwide that rely on ManageEngine ADManager Plus for Active Directory management. Successful exploitation can lead to arbitrary command execution on the underlying system, potentially allowing attackers to gain full control over the affected server. This can result in unauthorized access to sensitive directory data, manipulation or deletion of user accounts, privilege escalation, and disruption of directory services. The compromise of Active Directory infrastructure can have cascading effects, enabling attackers to move laterally across networks, access other critical systems, and exfiltrate confidential data. The high severity and scope change mean that the vulnerability can affect multiple components and systems beyond the initial target, increasing the risk of widespread damage. Organizations in sectors with high dependency on Active Directory for identity and access management, such as finance, healthcare, government, and large enterprises, face elevated risks. The absence of known exploits in the wild currently provides a window for proactive defense, but the potential for rapid weaponization remains high given the nature of the vulnerability.

1. Immediately apply the official patch or update from Zohocorp once version 8024 or later is available to remediate the vulnerability. 2. Until patches are deployed, restrict access to the ManageEngine ADManager Plus interface to trusted administrators only, ideally via VPN or secure network segments. 3. Implement strict input validation and sanitization on any custom scripts or user inputs within the ADManager Plus environment to prevent injection of malicious commands. 4. Monitor logs and network traffic for unusual command execution patterns or unauthorized access attempts related to the Custom Script component. 5. Employ the principle of least privilege by limiting user permissions within ADManager Plus to only those necessary for their role, reducing the impact of compromised accounts. 6. Use application-layer firewalls or web application firewalls (WAFs) to detect and block command injection attempts targeting the vulnerable component. 7. Conduct regular security assessments and penetration testing focused on administrative tools and interfaces to identify similar vulnerabilities proactively. 8. Educate administrators on the risks of executing untrusted scripts and enforce policies for script approval and review before deployment.
