CVE-2000-0696 in Solaris Answerbook2
Summary
by MITRE
The administration interface for the dwhttpd web server in Solaris AnswerBook2 does not properly authenticate requests to its supporting CGI scripts, which allows remote attackers to add user accounts to the interface by directly calling the admin CGI script.

The vulnerability identified as CVE-2000-0696 represents a critical authentication flaw within the dwhttpd web server component of Solaris AnswerBook2, a documentation and support system distributed by Sun Microsystems. This weakness stems from insufficient input validation and access control mechanisms that govern how administrative functions are invoked through the web interface. The vulnerability specifically affects the administrative CGI scripts that handle user account management operations, creating a pathway for unauthorized remote exploitation that bypasses normal authentication procedures.
The technical implementation of this flaw resides in the improper handling of CGI script requests within the dwhttpd web server environment. When administrators access the AnswerBook2 interface, legitimate requests to administrative functions should be authenticated before execution. However, the vulnerability allows attackers to directly invoke these administrative CGI scripts without proper authentication, effectively granting them the same privileges as authorized administrators. This occurs because the web server does not properly validate whether incoming requests originate from authenticated users or if they contain appropriate authorization tokens. The flaw essentially removes the authentication layer that should protect sensitive administrative operations from unauthorized access.
The operational impact of this vulnerability extends beyond simple privilege escalation to encompass complete system compromise through unauthorized user account creation. Attackers who exploit this vulnerability can add new user accounts with administrative privileges, potentially establishing persistent access to the system. This capability allows for long-term unauthorized control of the affected system, as attackers can create accounts that persist beyond the initial exploitation window. The vulnerability affects systems running Solaris AnswerBook2, which typically operates on Solaris operating systems and can be found in enterprise environments where comprehensive system documentation and support tools are deployed. The remote nature of the attack means that exploitation can occur from any network location without requiring physical access to the system.
Mitigation strategies for CVE-2000-0696 should focus on immediate patch application from Sun Microsystems, as this vulnerability was addressed through official security updates. Organizations should also implement network segmentation to limit access to administrative interfaces, ensuring that only authorized personnel can reach these critical systems. Access controls should be strengthened through proper authentication mechanisms and the implementation of network firewalls that restrict access to administrative ports and services. The vulnerability aligns with CWE-287, which describes improper authentication issues, and maps to ATT&CK technique T1078 for valid accounts and T1566 for phishing attacks that could be leveraged to gain initial access to the system before exploiting this specific vulnerability. System administrators should also conduct regular security audits to identify and remediate similar authentication weaknesses in other web applications and services within their environment.
