The vulnerability identified as CVE-2005-3035 affects Compuware DriverStudio Remote Control service version 2.7 and 3.0 beta 2, presenting a significant security risk that enables remote attackers to execute a denial of service attack resulting in system reboot. This flaw resides within the DSRsvc.exe process which operates on UDP port 9110, making it accessible to external network entities without proper authentication or authorization mechanisms. The service's design fails to implement adequate input validation or packet filtering controls, allowing malicious actors to exploit the communication protocol directly.
The technical implementation of this vulnerability stems from insufficient bounds checking and protocol handling within the DriverStudio service daemon. When malformed UDP packets are transmitted to port 9110, the service processes these packets without proper validation, leading to unexpected behavior that ultimately triggers a system reboot. This represents a classic buffer overflow or protocol parsing vulnerability where the service does not properly sanitize incoming data before processing. The flaw operates at the network level, leveraging UDP's connectionless nature to bypass traditional security controls that might otherwise prevent such attacks.
From an operational impact perspective, this vulnerability creates severe consequences for affected systems as it allows adversaries to remotely disrupt service availability without requiring any authentication credentials or privileged access. The denial of service condition manifests as complete system reboot, effectively rendering the targeted machine unavailable for legitimate operations. This attack vector is particularly dangerous because it can be executed from anywhere on the network, requiring no special privileges or knowledge of system credentials. Organizations relying on Compuware DriverStudio services face potential business disruption and operational downtime that could affect critical system functions or user access.
The vulnerability aligns with CWE-121, which addresses buffer overflow conditions in data processing, and demonstrates characteristics consistent with ATT&CK technique T1499.004 for network denial of service attacks. The attack requires minimal resources and technical expertise to execute, making it attractive to threat actors seeking to disrupt operations. Organizations should implement immediate network segmentation to isolate affected systems, disable unnecessary UDP services, and apply vendor-provided patches or workarounds. Network access control lists should be configured to restrict access to port 9110, and monitoring should be implemented to detect anomalous UDP traffic patterns. The remediation approach should include comprehensive network security assessments to identify similar vulnerabilities in other services and establish proper input validation controls across all network-facing applications.
