An LDAP Injection vulnerability in WatchGuard Fireware OS may allow a remote unauthenticated attacker to retrieve sensitive information from a connected LDAP authentication server through an exposed authentication or management web interface. This vulnerability may also allow a remote attacker to authenticate as an LDAP user with a partial identifier if they additionally have that user's valid passphrase. Organizations should prioritize patching immediately.
The severity of this vulnerability is classified as high, with a CVSS score of 7.0. This indicates a significant risk to organizations, particularly those relying on LDAP authentication mechanisms. The potential for unauthorized access to sensitive data necessitates immediate attention from security teams.
The exploitation status for this vulnerability is currently classified as high, meaning that the risk of exploitation is considerable. Organizations using affected versions should take action to mitigate this risk.
Consequently, organizations utilizing Fireware OS should assess their deployment and address this vulnerability promptly to prevent potential exploitation.
Vulnerability Details
The vulnerability allows attackers to perform LDAP Injection attacks, which can result in unauthorized access and retrieval of sensitive information. It affects Fireware OS versions from 12.0 through 12.11.6, from 12.5 through 12.5.15, and from 2025.1 through 2026.0. The vulnerability is classified under CWE-90.
Technical Analysis
The root cause of this vulnerability stems from improper validation of user input in LDAP queries. Attackers can exploit this flaw via the network, with a low attack complexity and no required privileges. The attack does not require user interaction, meaning it can be executed remotely without user involvement.
The confidentiality and integrity impacts are rated as high, indicating that sensitive data could be compromised. However, there is no impact on availability. This combination of factors makes the vulnerability particularly concerning for organizations using the affected versions of Fireware OS.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized access to sensitive LDAP information, which could lead to further attacks or data breaches. Given the high CVSS score, organizations should address the vulnerability in their priority patch cycle. The blast radius is significant due to the nature of LDAP services in many enterprise environments.
