CVE-2002-2170 in Badblue
Summary
by MITRE
Working Resources Inc. BadBlue Enterprise Edition 1.7 through 1.74 attempts to restrict administrator actions to the IP address of the local host, but does not provide additional authentication, which allows remote attackers to execute arbitrary code via a web page containing an HTTP POST request that accesses the dir.hts page on the localhost and adds an entire hard drive to be shared.

The vulnerability described in CVE-2002-2170 represents a critical security flaw in Working Resources Inc. BadBlue Enterprise Edition versions 1.7 through 1.74. This issue stems from a fundamental misconfiguration in the web server's access control mechanisms where the system attempts to limit administrative privileges to the local host address while simultaneously failing to implement proper authentication measures. The flaw creates a dangerous scenario where remote attackers can bypass the intended local-only restriction through carefully crafted web page requests that leverage HTTP POST methods to interact with the vulnerable dir.hts page.
The technical implementation of this vulnerability demonstrates a classic case of insufficient authentication and access control weaknesses that fall under CWE-284, which addresses improper access control mechanisms. The system's design assumes that restricting access to localhost alone would be sufficient protection, but this approach fails to account for the possibility of attackers crafting malicious web pages that can trigger HTTP POST requests from remote locations. When these requests reach the vulnerable server, they can access the dir.hts page which serves as an entry point for administrative functions that should remain restricted to local access only.
The operational impact of this vulnerability is severe and far-reaching, as it allows remote attackers to execute arbitrary code on the affected system with administrator privileges. The specific attack vector involves creating a web page that contains an HTTP POST request designed to access the dir.hts page on the localhost, which then enables the attacker to add entire hard drives to be shared. This capability essentially grants the attacker complete control over the file sharing functionality and potentially the entire system, as the administrative interface can be accessed without proper authentication. The vulnerability is particularly dangerous because it operates entirely through web-based attacks that can be delivered via standard web browsers without requiring any specialized tools or local access to the target system.
From an ATT&CK framework perspective, this vulnerability maps to multiple techniques including T1190 for exploiting vulnerabilities in web applications and T1078 for legitimate credentials and access. The attack chain involves initial access through a malicious web page, followed by privilege escalation and lateral movement through the exploitation of the administrative interface. The vulnerability also relates to T1059 for command and scripting interpreter, as the attacker can execute arbitrary code on the target system. Organizations running this vulnerable software are particularly at risk because the attack can be executed entirely from external locations, making it difficult to detect and prevent through traditional network monitoring approaches.
The mitigation strategies for this vulnerability should focus on immediate remediation through software updates to versions that address the access control flaws. Administrators should also implement network-level restrictions to prevent external access to administrative interfaces and ensure that all web servers are properly configured with robust authentication mechanisms. Additional protective measures include implementing web application firewalls, conducting regular security assessments, and ensuring that administrative functions are not exposed to untrusted networks. The vulnerability serves as a prime example of why layered security approaches are essential and why relying solely on network-based access controls without proper authentication mechanisms creates significant security risks. Organizations should also consider implementing network segmentation to isolate critical systems and limit the potential impact of such vulnerabilities.
