CVE-2002-1441 in Steelarrow
Summary
by MITRE
Multiple buffer overflows in Tomahawk SteelArrow before 4.5 allow remote attackers to execute arbitrary code via (1) the Steelarrow Service (Steelarrow.exe) using a long UserIdent Cookie header, (2) DLLHOST.EXE (Steelarrow.dll) via a request for a long .aro file, or (3) DLLHOST.EXE via a Chunked Transfer-Encoding request.

The vulnerability identified as CVE-2002-1441 represents a critical security flaw affecting the Tomahawk SteelArrow web application server software prior to version 4.5. This vulnerability manifests through multiple attack vectors that collectively demonstrate the severity of buffer overflow conditions within the application's handling of user input. The affected components include the Steelarrow Service executable Steelarrow.exe, the Steelarrow.dll dynamic link library, and the DLLHOST.EXE process that manages dynamic library hosting. These components form a critical part of the web server infrastructure that processes incoming HTTP requests and manages application-specific file handling operations.
The technical implementation of this vulnerability stems from inadequate input validation and memory management practices within the SteelArrow software architecture. The first attack vector involves the manipulation of the UserIdent Cookie header in HTTP requests, where an attacker can craft a specially formatted cookie containing an excessively long string of data that exceeds the allocated buffer space in the Steelarrow.exe service. This buffer overflow condition occurs when the application fails to properly validate the length of cookie data before copying it into fixed-size memory buffers. The second vector targets the DLLHOST.EXE process through requests for .aro files, which are application-specific data files that trigger similar buffer overflow conditions when the file names or content exceed predetermined memory limits. The third attack vector exploits Chunked Transfer-Encoding requests, where the application's handling of HTTP chunked data streams creates opportunities for attackers to overflow buffers through carefully crafted request structures.
The operational impact of CVE-2002-1441 is severe and encompasses complete system compromise capabilities for remote attackers. Successful exploitation of any of these three vectors can result in arbitrary code execution on the vulnerable system, potentially allowing attackers to gain full control over the web server. This vulnerability directly maps to CWE-121, which describes stack-based buffer overflow conditions, and CWE-122, which covers heap-based buffer overflow scenarios that can occur when applications fail to properly validate input lengths. The attack surface is particularly concerning given that these vulnerabilities affect core web server components that handle network traffic and file processing operations. The exploitability of these conditions aligns with ATT&CK technique T1059, which involves command and scripting interpreter usage, as successful exploitation would enable attackers to execute arbitrary commands on the compromised system.
The mitigation strategies for this vulnerability require immediate attention and include several critical measures that align with industry best practices for buffer overflow remediation. Organizations must upgrade to Tomahawk SteelArrow version 4.5 or later, which contains patches addressing the specific buffer overflow conditions. Additionally, implementing input validation controls at the network perimeter through firewalls and web application firewalls can help detect and block malicious requests before they reach the vulnerable components. The application should be configured to limit cookie sizes and file name lengths to prevent buffer overflow conditions, while also implementing proper memory management practices that include bounds checking and stack canaries. Network segmentation and privilege separation should be employed to limit the potential impact of successful exploitation, as outlined in the MITRE ATT&CK framework's recommendations for defending against remote code execution vulnerabilities. Regular security assessments and code reviews should focus on identifying similar buffer overflow conditions in other applications and systems to prevent analogous vulnerabilities from being introduced.
