CVE-2026-111100 in Kiloview
Summary
by MITRE • 10/23/2026
The ONVIF device service on the E3 responds to certain informational requests without requiring authentication. A remote, unauthenticated party can retrieve detailed device identifiers along with a list of configured user accounts and their privilege levels. This aids attackers in fingerprinting vulnerable devices and preparing targeted credential attacks.

The vulnerability identified within the ONVIF device service on the E3 represents a critical authentication bypass that allows remote, unauthenticated actors to extract sensitive system information. The core technical flaw lies in the improper enforcement of access control policies for specific informational endpoints exposed by the Network Video Transport Interface protocol implementation. Instead of requiring valid credentials or session tokens before processing requests designed to return device metadata and user configuration details, the service accepts these queries from any source on the network. This lack of authentication mechanism effectively turns a management interface into an open information disclosure channel, violating fundamental security principles regarding the protection of administrative data.
From a technical perspective, this flaw enables attackers to perform detailed fingerprinting of the target device without triggering alarms or requiring prior compromise of user accounts. By querying these unprotected endpoints, an adversary can retrieve precise hardware identifiers, firmware versions, and model-specific characteristics that are often used to identify known vulnerabilities associated with specific software revisions. Furthermore, the exposure of a list of configured user accounts along with their assigned privilege levels provides attackers with valuable intelligence for planning subsequent attacks. Knowing which usernames exist and whether they possess administrative or high-level privileges allows threat actors to prioritize brute-force attempts against privileged accounts rather than guessing randomly, significantly increasing the efficiency and success rate of credential-based intrusion attempts.
The operational impact of this vulnerability extends beyond simple information leakage, as it serves as a critical enabler for more severe security breaches. The ability to enumerate user accounts facilitates targeted password spraying or dictionary attacks where attackers focus on high-value targets identified by their privilege levels. This reduces the noise and detection probability associated with blind brute-force attempts against non-existent users. Additionally, detailed device identifiers can be cross-referenced with public vulnerability databases such as CVEs to determine if specific known exploits are applicable to the running firmware version. Consequently, this single flaw lowers the barrier for entry significantly, allowing even low-skilled attackers to compromise the integrity and confidentiality of the surveillance system by leveraging publicly available tools and techniques.
In alignment with industry standards, this vulnerability maps directly to CWE-287 Improper Authentication, as the system fails to adequately verify identity before granting access to sensitive data. It also relates to CWE-200 Exposure of Sensitive Information to an Unauthorized Actor, given that user account lists and device identifiers are considered confidential administrative details. From a tactical standpoint within the MITRE ATT&CK framework, this behavior supports reconnaissance activities categorized under T1592 Gather Victim Host Information and T1589 Gather Victim Identity Information. The exposure of privilege levels specifically aids in identifying high-value targets for subsequent exploitation phases such as Credential Access or Privilege Escalation.
To mitigate this risk, immediate remediation should focus on enforcing strict authentication requirements for all ONVIF device service endpoints that return sensitive configuration data. Administrators must ensure that the firmware is updated to a version where these informational requests are gated behind proper credential verification mechanisms. If an update is not immediately available, network-level controls such as firewall rules or access control lists should be implemented to restrict access to the affected ports exclusively from trusted management subnets. Additionally, disabling unnecessary ONVIF services if they are not required for operational functionality can reduce the attack surface and eliminate exposure of these sensitive endpoints entirely until a permanent patch is applied.
