CVE-2007-4445 in rFactor
Summary
by MITRE
Image Space rFactor 1.250 and earlier allows remote attackers to cause a denial of service (daemon crash) via (1) an ID 0x30 packet, (2) an ID 0x38 packet, and an invalid 13-bit integer in (3) an ID 0x60 packet and (4) an ID 0x68 packet; and a denial of service (UDP port block) via (5) an ID 0x20 packet and (6) an ID 0x28 packet.

The vulnerability identified as CVE-2007-4445 affects Image Space rFactor version 1.250 and earlier, presenting a significant security risk through multiple packet handling flaws that can lead to denial of service conditions. This vulnerability specifically targets the daemon process that manages network communications within the rFactor application, creating opportunities for remote attackers to disrupt service availability. The flaw exists in the packet processing logic where the application fails to properly validate incoming network packets before processing them, leading to potential daemon crashes and network port blocking.
The technical implementation of this vulnerability involves several distinct packet types that trigger different failure modes within the rFactor daemon. Attackers can exploit ID 0x30 and ID 0x38 packets by sending malformed data that causes the daemon to crash, while ID 0x60 and ID 0x68 packets require manipulation of a 13-bit integer field to achieve the same effect. Additionally, ID 0x20 and ID 0x28 packets specifically target UDP port functionality, causing the daemon to block network ports and prevent legitimate connections. These packet types represent different layers of the application's network protocol implementation, indicating a systemic issue in input validation across multiple communication channels.
The operational impact of CVE-2007-4445 extends beyond simple service disruption to potentially compromise the entire availability of network services provided by the affected rFactor instances. When the daemon crashes due to malformed packet processing, the service becomes unavailable to legitimate users, creating a denial of service condition that can persist until manual intervention occurs. The UDP port blocking aspect compounds this issue by preventing new connections from establishing, effectively creating a complete network service outage. This vulnerability particularly affects networked gaming environments where rFactor serves as a client-server application, potentially disrupting multiplayer gaming sessions and network communications.
From a cybersecurity perspective, this vulnerability aligns with CWE-129, which addresses improper validation of input ranges, and CWE-242, which covers the use of dangerous functions in network protocols. The attack vectors described in CVE-2007-4445 correspond to techniques found in the ATT&CK framework under T1498, specifically targeting network denial of service through protocol manipulation. The vulnerability represents a classic example of a buffer overflow or input validation flaw where the application fails to properly sanitize network inputs before processing them, leading to unpredictable behavior and system instability.
Mitigation strategies for CVE-2007-4445 should prioritize immediate patching of affected rFactor versions, as the vulnerability affects a core network component that cannot be effectively secured through network segmentation or firewall rules alone. Network administrators should implement monitoring solutions to detect anomalous packet patterns that could indicate exploitation attempts, while also configuring network access controls to limit exposure to untrusted networks. The vulnerability's nature suggests that implementing proper input validation and bounds checking in the application's packet handling code would resolve the issue, though this requires updating to a patched version of rFactor that addresses these specific validation flaws in the network protocol implementation.
