The vulnerability identified as CVE-2007-5222 represents a critical sql injection flaw within the MAXdev MDPro content management system version 1.0.76. This vulnerability specifically targets the index.php script and exploits a weakness in how the application processes incoming http referer headers. The flaw allows remote attackers to inject malicious sql commands by manipulating the "firefox id=" parameter within the referer header, creating a pathway for unauthorized database access and potential system compromise. The vulnerability stems from inadequate input validation and sanitization mechanisms that fail to properly escape or filter user-supplied data before incorporating it into sql query structures.
The technical exploitation of this vulnerability follows a classic sql injection attack pattern where attacker-controlled data flows directly into database queries without proper sanitization. When the mdpro application processes the referer header containing the malicious "firefox id=" substring, it concatenates this data into sql statements without appropriate escaping or parameterization. This creates an environment where an attacker can manipulate the sql execution flow to perform unauthorized operations such as data extraction, modification, or deletion. The vulnerability specifically leverages the referer header as an attack vector because many applications do not properly validate or sanitize data from this http header field, which is often used for tracking purposes but can contain user-controllable content.
The operational impact of this vulnerability extends beyond simple data theft to encompass complete system compromise and unauthorized administrative access. An attacker exploiting this vulnerability could potentially extract sensitive information from the database including user credentials, personal data, and system configuration details. The remote nature of the attack means that exploitation can occur from anywhere on the internet without requiring physical access to the target system. This vulnerability also aligns with attack patterns documented in the mitre att&ck framework under the execution and credential access domains, where attackers leverage application vulnerabilities to gain persistent access and escalate privileges within the compromised environment. The vulnerability demonstrates poor application security practices and highlights the importance of implementing proper input validation and output encoding mechanisms.
Mitigation strategies for this vulnerability should focus on implementing robust input validation and parameterized query execution throughout the application codebase. The most effective immediate fix involves sanitizing all user-supplied data, particularly data extracted from http headers like referer, before incorporating it into sql queries. This approach aligns with cwe-89, which specifically addresses sql injection vulnerabilities in software applications. Organizations should implement proper input filtering and output encoding techniques to prevent malicious data from being interpreted as sql commands. Additionally, the application should be updated to a newer version of mdpro that addresses this vulnerability, as version 1.0.76 appears to be outdated and likely contains other unpatched security flaws. Network-level protections such as web application firewalls and intrusion detection systems can provide additional defense-in-depth measures, though they should not be relied upon as the sole mitigation strategy. Regular security assessments and code reviews should be conducted to identify and remediate similar vulnerabilities across the entire application stack.
