CVE-2007-6503 in Hosting Controller
Summary
by MITRE
Multiple unspecified vulnerabilities in Hosting Controller 6.1 Hot fix 3.3 and earlier allow remote authenticated users to (1) import an arbitrary plan via a request to hosting/importhostingplans.asp; or (2) change an arbitrary plan via a request to hosting/AutoSignUpPlans.asp with the (a) save, (b) 30, and (c) d_30 parameters.

The vulnerability described in CVE-2007-6503 affects Hosting Controller version 6.1 Hot fix 3.3 and earlier, representing a critical security flaw in web hosting management software that could enable authenticated attackers to manipulate hosting plan configurations. This vulnerability exists within the administrative interfaces of the hosting platform, specifically targeting two distinct attack vectors that allow for unauthorized plan modifications. The issue stems from insufficient input validation and access control mechanisms within the hosting plan management functions, creating opportunities for privilege escalation and unauthorized system modifications.
The technical implementation of this vulnerability involves two primary attack paths through specific.asp files within the hosting controller application. The first vector allows attackers to import arbitrary hosting plans through requests directed to hosting/importhostingplans.asp, while the second vector enables plan modification through hosting/AutoSignUpPlans.asp with specific parameter manipulation including save, 30, and d_30 parameters. These attack paths demonstrate a classic case of insufficient authorization checks and input sanitization, where the application fails to properly validate user permissions before processing plan modification requests. The vulnerability essentially allows authenticated users to bypass normal access controls and perform operations that should be restricted to administrators or authorized personnel only.
From an operational impact perspective, this vulnerability presents significant risks to hosting providers and their customers. Attackers who can authenticate to the hosting controller system could potentially modify hosting plans to gain elevated privileges, create unauthorized plans with malicious configurations, or disrupt existing service offerings. The ability to import arbitrary plans could lead to the creation of backdoor configurations or the injection of malicious code into the hosting environment. Additionally, the capability to change arbitrary plans could result in service disruption, unauthorized resource allocation, or potential data exposure. This vulnerability directly impacts the integrity and availability of hosting services, potentially allowing attackers to compromise multiple customer accounts or services within the hosting environment.
The vulnerability aligns with CWE-284 (Improper Access Control) and CWE-20 (Improper Input Validation) categories, representing multiple weaknesses in the software's security architecture. From an attack framework perspective, this vulnerability maps to several ATT&CK techniques including T1078 (Valid Accounts), T1566 (Phishing), and T1068 (Exploitation for Privilege Escalation). The attack chain typically begins with gaining legitimate authentication credentials, followed by exploitation of the access control weaknesses to modify hosting configurations. Organizations should implement immediate mitigations including applying the latest security patches, implementing strict input validation for all parameters, enforcing proper access controls, and monitoring for unauthorized plan modifications. Network segmentation and role-based access controls should be enforced to limit the scope of potential exploitation, while regular security audits should be conducted to identify similar vulnerabilities in other system components. The vulnerability underscores the importance of maintaining up-to-date security patches and implementing defense-in-depth strategies to protect critical infrastructure components.
