CVE-2025-48748 is a critical security vulnerability identified in Netwrix Directory Manager (formerly known as Imanami GroupID) up to version 10.0.7784.0. The vulnerability arises from the presence of a hard-coded password embedded within the software. Hard-coded passwords represent a severe security flaw because they are static credentials that cannot be changed by the user or administrator, and if discovered by an attacker, they provide a direct avenue for unauthorized access. In this case, the vulnerability has a CVSS v3.1 base score of 10.0, indicating the highest severity level. The CVSS vector (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H) reveals that the attack can be performed remotely over the network without any privileges or user interaction, and it results in complete compromise of confidentiality, integrity, and availability of the affected system. The scope is changed, meaning the vulnerability affects components beyond the initially vulnerable component, potentially impacting the entire system or network. The CWE associated with this vulnerability is CWE-798, which specifically relates to the use of hard-coded credentials. Although no known exploits are currently reported in the wild, the nature of the vulnerability and its severity make it a prime target for attackers once exploit code becomes available. The lack of a published patch or mitigation guidance in the provided information further elevates the risk. Netwrix Directory Manager is an identity and access management tool used to manage Active Directory environments, which are critical infrastructure components in many organizations. Exploitation of this vulnerability could allow attackers to gain unauthorized access to directory management functions, potentially leading to widespread privilege escalation, data exfiltration, and disruption of enterprise authentication and authorization services.

For European organizations, the impact of CVE-2025-48748 could be profound. Many enterprises and public sector entities across Europe rely on Active Directory and similar directory services for identity and access management. A compromise of Netwrix Directory Manager through this hard-coded password vulnerability could allow attackers to bypass authentication controls, manipulate user permissions, and gain persistent footholds within corporate networks. This could lead to unauthorized access to sensitive personal data protected under GDPR, resulting in regulatory penalties and reputational damage. Additionally, the integrity and availability of directory services could be disrupted, affecting business continuity and critical operations. Given the criticality of identity management in sectors such as finance, healthcare, government, and telecommunications, exploitation could facilitate further lateral movement and targeted attacks, including ransomware deployment or espionage. The vulnerability’s remote exploitability without user interaction increases the risk of automated attacks and worm-like propagation within vulnerable networks.

To mitigate this vulnerability, European organizations should immediately audit their Netwrix Directory Manager installations to identify affected versions. Since no patch or update is currently referenced, organizations should consider the following specific actions: 1) Disable or isolate Netwrix Directory Manager instances from external network access to limit exposure. 2) Implement network segmentation and strict firewall rules to restrict access to directory management interfaces only to trusted administrative hosts. 3) Conduct credential audits and monitor for any unauthorized access attempts or anomalous authentication events related to Netwrix Directory Manager. 4) If possible, replace or upgrade the software to a version that does not contain the hard-coded password or apply vendor-provided workarounds once available. 5) Employ multi-factor authentication (MFA) on all administrative accounts interacting with directory services to reduce the risk of credential misuse. 6) Enhance logging and alerting on directory management activities to detect potential exploitation attempts early. 7) Prepare incident response plans specifically addressing potential compromise scenarios involving directory management tools. These targeted measures go beyond generic advice by focusing on containment, detection, and compensating controls until a vendor patch is released.
