CVE-2023-38547 is a critical vulnerability in Veeam ONE, a widely used application for monitoring and reporting on Veeam Backup & Replication environments. This vulnerability allows an unauthenticated user to gain information about the SQL server connection that Veeam ONE uses to access its configuration database. The implications of this vulnerability are severe, as it may lead to remote code execution on the SQL server hosting the configuration database.
The vulnerability has been assigned a CVSS score of 9.8, indicating a critical severity level. This high rating emphasizes the potential impact on organizations that utilize Veeam ONE. As attackers may leverage this vulnerability to gain unauthorized access and execute arbitrary code, organizations must take immediate action to protect their systems.
Risk to organizations includes unauthorized access to sensitive data and the potential for a compromise of the SQL server. Given the critical nature of this vulnerability, organizations should prioritize patching immediately.
Currently, there are no known exploits publicly available for this vulnerability, but the risks associated with it necessitate swift action to mitigate potential exploitation.
Organizations using affected versions of Veeam ONE should ensure they are aware of this vulnerability and the necessary steps to remediate it.
Vulnerability Details
According to the official description, CVE-2023-38547 allows an unauthenticated user to gain information about the SQL server connection used by Veeam ONE for accessing its configuration database. This vulnerability is classified under CWE-200, which pertains to information exposure. The CVSS v3.1 vector for this vulnerability is AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H, signifying a network attack vector with low complexity and no privileges required.
The publication date of this vulnerability is November 7, 2023. Organizations must be aware that all versions of Veeam ONE prior to the vendor patch are vulnerable.
Technical Analysis
The root cause of CVE-2023-38547 stems from insufficient protection of sensitive information regarding the SQL server connection. The attack vector is classified as network-based, allowing unauthenticated attackers to exploit this vulnerability remotely. Given that the attack complexity is low, the risk is heightened due to the ease of exploitation.
This vulnerability requires no privileges, and user interaction is not necessary for exploitation. The potential impacts on confidentiality, integrity, and availability are all high, as attackers may gain unauthorized access to sensitive data and execute harmful actions on the SQL server hosting the Veeam ONE configuration database.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2023-38547 is significant. Organizations using Veeam ONE may face severe data breaches if this vulnerability is exploited. Attackers may leverage this vulnerability to gain access to SQL server configurations and potentially execute arbitrary code, leading to unauthorized access to critical infrastructure.
The urgency assessment based on the critical CVSS score indicates that organizations should address this vulnerability in their priority patch cycle. The potential blast radius is extensive, affecting not only the Veeam ONE application but also the underlying SQL server and any connected systems.
