CVE-2024-40060 identifies a vulnerability in the go-chart library version 2.1.1, specifically an infinite loop within the drawCanvas() function. go-chart is a Go language library used to generate charts and graphical data representations, often integrated into web services and backend systems. The infinite loop occurs when the drawCanvas() function enters a state where it never terminates, causing the application to consume excessive CPU resources indefinitely. This behavior results in a denial-of-service (DoS) condition, where legitimate users may experience service degradation or complete unavailability. The vulnerability is remotely exploitable without any authentication or user interaction, increasing its risk profile. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) indicates network attack vector, low attack complexity, no privileges or user interaction required, unchanged scope, no confidentiality or integrity impact, but high impact on availability. The weakness is classified under CWE-835 (Loop with Unreachable Exit Condition), highlighting a programming logic flaw. No patches or fixes have been officially released at the time of publication, and no active exploitation has been reported. Organizations relying on go-chart for dynamic chart rendering should assess their exposure and consider interim mitigations.

The primary impact of CVE-2024-40060 is a denial-of-service condition caused by an infinite loop in the drawCanvas() function. This can lead to resource exhaustion on affected systems, resulting in application crashes, degraded performance, or complete service outages. Since the vulnerability can be triggered remotely without authentication or user interaction, attackers can easily disrupt services, affecting availability. While confidentiality and integrity remain intact, the availability impact can cause significant operational disruptions, especially for services relying on real-time or high-availability chart rendering. This may affect web applications, dashboards, monitoring tools, and any automated reporting systems using go-chart. The lack of patches increases the window of exposure, and organizations may face increased risk of downtime or service interruptions until mitigations are applied.

To mitigate CVE-2024-40060, organizations should first monitor the go-chart project for official patches or updates addressing the infinite loop issue and apply them promptly once available. In the interim, developers can review and modify the drawCanvas() function to add loop exit conditions or timeouts to prevent infinite execution. Implementing resource limits such as CPU usage caps or container-level constraints can reduce the impact of potential infinite loops. Additionally, deploying web application firewalls (WAFs) or network-level rate limiting can help detect and block abnormal requests targeting the vulnerable function. Conduct thorough code audits for similar looping constructs in custom integrations. Finally, consider isolating services using go-chart to minimize the blast radius of a potential DoS attack and maintain robust monitoring to detect unusual resource consumption patterns early.
