Vulnerability Details
The vulnerability identified as CVE-2026-1007 is characterized by incorrect authorization within the virtual gateway component of Devolutions Server. This flaw allows attackers to bypass IP deny rules, which can lead to unauthorized access to sensitive data and systems. The vulnerability affects the following versions of Devolutions Server: 2025.3.1 through 2025.3.12.
According to the CVSS 3.1 metrics, this vulnerability has a base score of 7.6, categorized as high severity. The attack vector is defined as network-based, with low attack complexity. A high level of privileges is required for exploitation, and user interaction is not necessary.
The vulnerability has a confidentiality impact rated as low, while the integrity impact is rated as high, indicating that an attacker could modify or manipulate data. There is no impact on availability.
This vulnerability corresponds to CWE-863, indicating a flaw in the authorization process. Organizations should take immediate steps to remediate this issue.
Technical Analysis
The root cause of CVE-2026-1007 lies in the incorrect authorization implementation within the virtual gateway component of Devolutions Server. Attackers can exploit this flaw over the network, leveraging the high privileges required to bypass security measures intended to restrict access based on IP addresses.
The attack complexity is low, meaning that an attacker with appropriate privileges can exploit the vulnerability without significant effort. No user interaction is required, which further increases the risk, allowing for wide-scale exploitation if the vulnerability is not addressed.
The confidentiality impact is rated low, suggesting that while sensitive information may be accessed, the primary risk lies in the integrity impact, which is rated high. An attacker can alter data without detection, potentially leading to data corruption or unauthorized actions.
Overall, the vulnerability presents a significant risk to organizations utilizing Devolutions Server, and immediate attention is warranted.
Risk & Impact Analysis
Risk to organizations includes the potential for unauthorized access to sensitive systems, leading to data breaches and integrity violations. The vulnerability's high CVSS score indicates a pressing need for remediation to mitigate the risk of exploitation.
The blast radius of this vulnerability is significant, as it affects multiple versions of the Devolutions Server software. An attacker exploiting this vulnerability could gain access to critical infrastructure, making it essential for organizations to prioritize patching immediately.
