CyberPanel, a popular web hosting control panel, contains a medium-severity vulnerability identified as CVE-2024-54679. This vulnerability allows unauthorized users to perform restartMySQL actions without the required FilemanagerAdmin capability, which can lead to potential disruptions in service availability.
The vulnerability was published on December 5, 2024, and affects versions of CyberPanel prior to commit 6778ad1. The CVSS score for this vulnerability is 4.3, indicating a medium severity level, which reflects its potential impact on system availability.
Organizations using CyberPanel should assess their exposure and understand the risk to their systems, as this vulnerability could be exploited to disrupt MySQL services. Immediate action is necessary to mitigate potential risks associated with this flaw.
Given the nature of this vulnerability and its exploitability, organizations should prioritize patching immediately. Failure to address this issue could result in unauthorized access to critical MySQL management features, leading to service interruptions.
Vulnerability Details
The vulnerability allows unauthorized users to restart MySQL services due to insufficient access controls in CyberPanel. The affected versions are all prior to the patch identified in commit 6778ad1. The vulnerability has a CVSS score of 4.3, indicating medium severity, with an availability impact assessed as low.
The vulnerability is classified under CWE-862, which pertains to missing authorization. This classification highlights the lack of proper access controls in place for critical administrative actions.
The vulnerability is exploitable via the network, with low attack complexity and requires low privileges. There is no user interaction required to exploit this vulnerability.
Technical Analysis
The root cause of this vulnerability arises from insufficient capability checks within the CyberPanel's codebase. Specifically, the system does not verify whether a user possesses the necessary FilemanagerAdmin capability when attempting to restart MySQL services.
Attackers may leverage this oversight to gain control over MySQL services without proper authorization. This could result in service disruptions or denial of service if exploited maliciously.
The attack vector is network-based, allowing remote exploitation without physical access to the system. Given the low attack complexity, this vulnerability poses a significant risk to organizations utilizing CyberPanel.
The required privileges for exploitation are low, meaning that potential attackers do not need elevated access to initiate an attack. This factor increases the likelihood of successful exploitation, particularly in environments with inadequate security controls.
Risk & Impact Analysis
Risk to organizations includes potential service disruptions caused by unauthorized MySQL restarts. As MySQL is a critical component in many web applications and services, the ability for unauthorized users to restart this service may lead to significant downtime.
Organizations should assess their exposure to this vulnerability, particularly those that rely on CyberPanel for managing their hosting environments. The potential blast radius of this vulnerability could affect all applications and services utilizing MySQL.
Given the CVSS score of 4.3, organizations should address in priority patch cycle. The longer this vulnerability remains unpatched, the greater the risk of exploitation.
