CVE-2007-6041 in Rigs Of Rogs
Summary
by MITRE
Buffer overflow in the Sequencer::queueMessage function in sequencer.cpp in the server in Rigs of Rods (RoR) before 0.33d SP1 allows remote attackers to cause a denial of service (daemon crash) and possibly execute arbitrary code by sending a nickname, then a vehicle name in a MSG2_USE_VEHICLE message, in which the combined length triggers the overflow.

The vulnerability identified as CVE-2007-6041 represents a critical buffer overflow flaw within the Rigs of Rods gaming server software, specifically within the Sequencer::queueMessage function located in sequencer.cpp. This issue affects versions prior to 0.33d SP1 and demonstrates a classic security weakness that can be exploited remotely by malicious actors. The vulnerability manifests when processing MSG2_USE_VEHICLE messages, which contain both nickname and vehicle name data fields that are concatenated and subsequently processed without adequate length validation or bounds checking.
The technical implementation of this flaw involves improper memory management within the server daemon's message handling mechanism. When a client sends a specially crafted MSG2_USE_VEHICLE message containing a nickname followed by a vehicle name, the combined length of these strings exceeds the allocated buffer space in the Sequencer::queueMessage function. This buffer overflow condition occurs because the application fails to validate the total length of the concatenated input data before copying it into a fixed-size buffer, creating an exploitable condition that can be leveraged for remote code execution or denial of service.
From an operational perspective, this vulnerability presents significant risks to Rigs of Rods server administrators and users who rely on the software for multiplayer gaming experiences. The remote exploitation capability means that attackers can potentially compromise server integrity without requiring local access or authentication. The vulnerability can result in immediate daemon crashes, causing service disruption for legitimate users, while the potential for arbitrary code execution opens pathways for more sophisticated attacks including persistent backdoor installation or complete server compromise. The nature of the attack vector makes it particularly dangerous as it can be executed by anyone with network access to the affected server.
The security implications align with CWE-121, which addresses stack-based buffer overflow conditions, and represents a clear violation of secure coding practices. This vulnerability can be mapped to ATT&CK technique T1203, which covers Exploitation for Client Execution, and T1499, covering Network Denial of Service, demonstrating both the execution and impact capabilities of the flaw. The attack requires minimal privileges and can be automated, making it particularly attractive to threat actors. Organizations should implement immediate mitigation strategies including applying the available patch for version 0.33d SP1, implementing network segmentation to restrict access to affected servers, and monitoring for suspicious network traffic patterns that may indicate exploitation attempts.
The broader implications extend beyond simple service disruption as this vulnerability demonstrates the importance of proper input validation and memory management in networked applications. The flaw highlights the necessity of applying defensive programming principles including bounds checking, input sanitization, and proper error handling to prevent similar issues in other software systems. Additionally, this vulnerability underscores the critical need for regular security updates and patch management processes, particularly for gaming servers that are frequently targeted due to their public accessibility and the potential for abuse in larger attack campaigns.
