CVE-2008-6717 in Signup
Summary
by MITRE
U&M Software Signup 1.0 and 1.1 does not require administrative authentication for all scripts in the admin/ directory, which allows remote attackers to have an unspecified impact via a direct request to (1) adminstart.php, (2) admineventtype.php, (3) admineventdetails.php, (4) admineventlist.php, (5) adminuserslist.php, (6) adminleaderslist.php, (7) admindatabase.php, and possibly (8) index.php.

The vulnerability identified as CVE-2008-6717 affects U&M Software Signup versions 1.0 and 1.1, representing a critical authentication bypass flaw that undermines the security posture of the application's administrative interface. This weakness stems from insufficient access control mechanisms within the software's administrative scripts, specifically those located in the admin/ directory. The vulnerability manifests when administrative functions are accessible without proper authentication, creating a significant security risk for organizations relying on this software for event management and user administration.
The technical implementation of this flaw involves the absence of authentication checks across multiple administrative endpoints, including adminstart.php, admineventtype.php, admineventdetails.php, admineventlist.php, adminuserslist.php, adminleaderslist.php, and admindatabase.php. These scripts are designed to handle sensitive administrative operations such as event type management, event details modification, user listings, leader management, and database operations. The vulnerability allows attackers to directly access these administrative functions without proper authorization, potentially enabling unauthorized modifications to critical system data and configurations. This represents a direct violation of the principle of least privilege and demonstrates a fundamental failure in access control implementation.
The operational impact of this vulnerability extends beyond simple unauthorized access, as it provides attackers with the capability to perform arbitrary administrative actions within the application. Attackers could potentially manipulate event data, modify user permissions, alter leadership assignments, or access sensitive database information through these unprotected administrative endpoints. The unspecified impact mentioned in the CVE description suggests that the consequences could range from data manipulation and privilege escalation to complete system compromise, depending on the specific capabilities of the affected scripts. This vulnerability directly aligns with CWE-284, which addresses improper access control, and represents a classic example of inadequate authorization checks in web applications.
The security implications of this vulnerability are particularly severe given that it affects multiple administrative functions within a single application, providing attackers with broad access to critical system controls. The fact that the vulnerability exists in versions 1.0 and 1.1 indicates that it was likely present in the software for an extended period, potentially exposing numerous installations to attack. Organizations using this software would have been unknowingly vulnerable to attacks that could result in data integrity compromise, unauthorized modifications to event management systems, and potential privilege escalation within the application's administrative interface. This vulnerability also maps to ATT&CK technique T1078 which covers valid accounts and privilege escalation through unauthorized access to administrative functions.
Mitigation strategies for this vulnerability should focus on implementing proper authentication controls across all administrative endpoints. Organizations should immediately ensure that all scripts within the admin/ directory require valid administrative authentication before execution. This involves implementing robust session management, proper user authentication mechanisms, and access control checks that verify administrative privileges before allowing access to sensitive functions. The software vendor should be contacted to obtain any available patches or updates that address this authentication bypass issue. Additionally, network segmentation and firewall rules should be implemented to restrict access to administrative endpoints to only authorized personnel. Regular security audits and penetration testing should be conducted to identify similar authentication bypass vulnerabilities in other parts of the application. The vulnerability also highlights the importance of following secure coding practices, including implementing proper input validation, authentication checks, and access control mechanisms as recommended by OWASP security guidelines. Organizations should also consider implementing additional monitoring and logging for administrative activities to detect unauthorized access attempts and potential exploitation of this vulnerability.
