Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

To mitigate CVE-2025-11670, European organizations should: 1) Immediately restrict the “Impersonate as Admin” permission to only the most trusted and necessary technicians, implementing strict access controls and regular reviews of privileged accounts. 2) Monitor and audit all activities performed by users with impersonation privileges to detect anomalous behavior indicative of exploitation attempts. 3) Apply the official patch or update to ManageEngine ADManager Plus version 8025 or later as soon as it becomes available from Zohocorp. 4) Employ network segmentation and least privilege principles to limit the exposure of administrative tools and credentials. 5) Use multi-factor authentication (MFA) for administrative accounts to reduce the risk of credential compromise. 6) Implement robust logging and alerting mechanisms to detect pass-the-hash or lateral movement techniques within the network. 7) Educate IT staff about the risks associated with privileged access and the importance of safeguarding credentials. These steps go beyond generic advice by focusing on privilege management, monitoring, and timely patching specific to the context of this vulnerability.

Description

Zohocorp ManageEngine ADManager Plus versions before 8025 are vulnerable to NTLM Hash Exposure. This vulnerability is exploitable only by technicians who have the “Impersonate as Admin” option enabled.

Impact

For European organizations, the exposure of NTLM hashes through this vulnerability can lead to significant security risks. Attackers who gain access to these hashes can perform pass-the-hash attacks, enabling lateral movement across networks and potentially compromising multiple systems. This undermines the confidentiality and integrity of enterprise credentials and can facilitate further attacks such as privilege escalation or data exfiltration. Organizations relying heavily on ManageEngine ADManager Plus for Active Directory management, especially those in sectors like finance, government, healthcare, and critical infrastructure, face increased risk. The vulnerability could disrupt trust in identity management and lead to regulatory compliance issues under GDPR if sensitive information is compromised. Additionally, the requirement that the attacker have “Impersonate as Admin” privileges means insider threats or compromised technician accounts pose a particular danger. The medium severity rating suggests that while the vulnerability is not trivially exploitable by external attackers without privileges, the impact within compromised environments can be substantial.

Architecture and Design · Separation of Privilege
Compartmentalize the system to have "safe" areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
