CVE-2007-3194 in myBloggie
Summary
by MITRE
** DISPUTED ** Multiple PHP remote file inclusion vulnerabilities in myBloggie 2.1.5 allow remote attackers to execute arbitrary PHP code via a URL in the bloggie_root_path parameter to (1) config.php; (2) db.php, (3) template.php, (4) functions.php, and (5) classes.php in includes/; (6) viewmode.php; and (7) blog_body.php. NOTE: another researcher disputes the vulnerability because the files are protected against direct requests, contain no relevant include statements, or do not exist.

The vulnerability identified as CVE-2007-3194 resides within myBloggie 2.1.5, a content management system that suffered from multiple remote file inclusion flaws affecting its core functionality. This vulnerability type falls under the category of insecure direct object reference and remote code execution, with the potential to be classified as CWE-88 for command injection or CWE-94 for code injection depending on the specific exploitation vector. The affected components include several critical include files within the includes directory, such as config.php, db.php, template.php, functions.php, classes.php, viewmode.php, and blog_body.php, all of which could be manipulated through the bloggie_root_path parameter.
The technical flaw manifests when the application fails to properly validate or sanitize user input before incorporating it into file inclusion operations. Attackers can exploit this weakness by supplying a malicious URL through the bloggie_root_path parameter, which gets processed by PHP's include or require functions. This creates a remote code execution scenario where arbitrary PHP code can be executed on the target server, potentially allowing full system compromise. The vulnerability operates at the application layer and can be categorized under ATT&CK technique T1190 for exploit for client execution, though in this case it represents a server-side exploitation vector. The flaw is particularly dangerous because it affects multiple include files, expanding the attack surface and providing multiple potential entry points for malicious actors.
The operational impact of this vulnerability is severe, as it allows remote attackers to execute arbitrary code with the privileges of the web server process. Successful exploitation could lead to complete system compromise, data theft, or the establishment of persistent backdoors. The vulnerability's remote nature means that attackers do not require physical access to the system, making it particularly attractive for automated attacks. Organizations running myBloggie 2.1.5 would be vulnerable to unauthorized access and potential data breaches, with the attack requiring minimal technical expertise to execute. This vulnerability type often results in the compromise of entire web applications and can be leveraged for further lateral movement within network infrastructures, making it a critical security concern that demands immediate remediation.
The vulnerability's disputed nature stems from various researcher perspectives regarding the actual exploitability of the affected files. Some researchers argue that the files are protected against direct requests, suggesting that the vulnerability may not be as straightforward as initially reported. Others contend that the include statements within these files do not properly validate external inputs, while some dispute the existence of certain files in the reported paths. However, the core issue remains that PHP's include functionality can be manipulated when proper input validation is not implemented, making this a legitimate concern for any web application utilizing dynamic include operations. The vulnerability's classification as disputed does not diminish the fundamental security implications of improper input handling in PHP applications, which continues to be a common weakness across numerous web platforms. Organizations should implement proper input validation, disable dangerous PHP functions, and employ web application firewalls to mitigate such risks, regardless of the specific dispute surrounding this particular CVE.
