Vulnerability Details
Icinga Web 2 is an open-source monitoring web interface, framework, and command-line interface. The vulnerability allows authenticated users with access to the configuration to create SSH resource files in unintended directories, leading to the execution of arbitrary code. This issue has been resolved in versions 2.8.6, 2.9.6, and 2.10 of Icinga Web 2. Users unable to upgrade should limit access to the Icinga Web 2 configuration.
The vulnerability has a CVSS score of 8.5, which falls within the high severity range. The attack vector is network-based, and the attack complexity is rated as high, indicating that some preconditions must be met for successful exploitation. The confidentiality, integrity, and availability impacts are all rated as high, emphasizing the critical nature of this vulnerability.
The vulnerability is classified under CWE-22, indicating improper restriction of operations within the bounds of a memory buffer.
Technical Analysis
The root cause of CVE-2022-24715 lies in the improper handling of SSH resource files by authenticated users. When these users can create files in unintended directories, it can lead to arbitrary code execution on the server. The attack vector is network-based, while the attack complexity is high, necessitating certain conditions to be met before an attack can be successful.
Privileges required for exploitation are low, meaning that an attacker only needs to be an authenticated user to initiate an attack. User interaction is not required, which increases the risk of exploitation. The vulnerability impacts confidentiality, integrity, and availability, each rated as high.
Risk & Impact Analysis
The real-world risk associated with CVE-2022-24715 is significant for organizations utilizing Icinga Web 2. The ability for authenticated users to execute arbitrary code poses a severe threat to system integrity and data confidentiality. In environments where Icinga Web 2 is widely deployed, the potential blast radius of an exploit could be extensive.
Organizations should assess their exposure to this vulnerability based on their deployment of Icinga Web 2. Given the high CVSS score of 8.5 and the availability of known exploits, it is critical that remediation efforts are prioritized. The urgency of addressing this vulnerability cannot be overstated, especially in light of its potential for significant impact.
