CVE-2007-0971 in Jupiter CMS
Summary
by MITRE
Multiple SQL injection vulnerabilities in Jupiter CMS 1.1.5 allow remote attackers to execute arbitrary SQL commands via the Client-IP HTTP header and certain other HTTP headers, which set the ip variable that is used in SQL queries performed by index.php and certain other PHP scripts. NOTE: the attack vector might involve _SERVER.

The vulnerability identified as CVE-2007-0971 represents a critical SQL injection flaw within Jupiter CMS version 1.1.5 that exposes the system to remote code execution attacks. This vulnerability stems from inadequate input validation mechanisms within the content management system's core scripts, specifically affecting the index.php file and other PHP components that process HTTP header information. The flaw allows malicious actors to inject arbitrary SQL commands through manipulation of HTTP headers, creating a direct pathway for database compromise and potential system takeover.
The technical implementation of this vulnerability occurs when the application processes the Client-IP HTTP header and other similar headers that ultimately set an ip variable within the application's execution context. This variable is subsequently incorporated into SQL queries without proper sanitization or parameterization, creating a classic SQL injection vector. The attack mechanism leverages the _SERVER superglobal array in PHP, which contains HTTP header information, making it particularly dangerous as it can be manipulated through standard HTTP request headers that are routinely processed by web applications. The vulnerability's exploitation requires minimal privileges and can be executed remotely without authentication, making it highly attractive to attackers.
The operational impact of this vulnerability extends beyond simple data theft, as successful exploitation could enable attackers to gain complete control over the database server hosting the Jupiter CMS installation. Attackers could potentially extract sensitive user credentials, modify content, delete database records, or even escalate privileges to execute arbitrary commands on the underlying server. The vulnerability affects the entire application stack, as multiple PHP scripts are susceptible to the same injection vectors, amplifying the potential damage. This weakness directly violates security principles outlined in the OWASP Top Ten, specifically addressing injection flaws that remain among the most critical web application vulnerabilities.
Mitigation strategies for CVE-2007-0971 require immediate implementation of input validation and parameterized queries throughout the Jupiter CMS codebase. Organizations should implement proper header sanitization mechanisms that filter or escape potentially malicious input from HTTP headers before they are processed by database queries. The recommended approach aligns with CWE-89 standards for SQL injection prevention, emphasizing the use of prepared statements and parameterized queries to eliminate the risk of injection attacks. Additionally, implementing proper access controls and network segmentation can reduce the attack surface, while regular security audits and code reviews should be conducted to identify similar vulnerabilities in other application components. The vulnerability also maps to ATT&CK technique T1190 for exploiting vulnerabilities and T1071 for application layer protocols, highlighting the multi-faceted nature of the threat landscape that this vulnerability creates.
