CVE-2024-42384
Cesanta
CVE-2024-42384 affects the Cesanta Mongoose Web Server, potentially leading to application crashes. This Integer Overflow or Wraparound vulnerability, present in version v7.14, can be exploited by sending a crafted TLS packet. Doing so results in a segmentation fault, effectively disrupting the web server's operation. While the CVSS score is 7.5, indicating high severity, the SOCRadar Vulnerability Risk Score (SVRS) of 68 suggests a moderate level of real-world threat. An attacker could leverage this vulnerability to cause a denial-of-service (DoS) condition, impacting availability. This highlights the need for patching and mitigation to maintain system stability and prevent service disruptions. Even with a SVRS below the critical threshold of 80, the potential for remote exploitation makes this a noteworthy security concern.
Description
CVE-2024-42384 is a vulnerability in the Cesanta Mongoose Web Server v7.14, specifically an Integer Overflow or Wraparound issue. An attacker could exploit this vulnerability by sending a specially crafted TLS packet, leading to a segmentation fault within the application. This could potentially result in a denial-of-service condition or even allow for remote code execution.
While the CVSS score is 7.5, indicating a high severity, the SVRS score is 34, suggesting a lower urgency. This disparity highlights the importance of SOCRadar's unique approach, incorporating additional intelligence beyond just the CVSS.
Key Insights
- Exploitation Potential: This vulnerability allows attackers to trigger a segmentation fault by sending a carefully crafted TLS packet. This could lead to a denial-of-service attack, preventing the targeted application from functioning.
- Severity: The vulnerability is classified as high severity due to the potential for a denial-of-service condition. However, the SVRS score indicates that the likelihood of exploitation is currently low.
- Impact: The vulnerability's impact is limited to applications using the Cesanta Mongoose Web Server v7.14. It doesn't affect other versions or applications.
- Mitigation: The developers of Cesanta Mongoose Web Server have released a patch for this vulnerability (v7.15). Updating to the latest version of the software is the most effective way to mitigate the risk.
Mitigation Strategies
- Upgrade to the latest version: Update the Cesanta Mongoose Web Server to version 7.15 or newer. This patch addresses the vulnerability and prevents potential exploitation.
- Network Segmentation: Implement network segmentation to isolate the web server from other critical systems. This can help limit the potential impact of a successful attack.
- Intrusion Detection System (IDS): Implement an IDS to monitor network traffic for suspicious activities that might indicate an attempt to exploit this vulnerability.
- Regular Security Audits: Conduct regular security audits to identify and mitigate potential vulnerabilities, including those related to integer overflow or wraparound.
