CVE-2007-3650 in myBloggie
Summary
by MITRE
myWebland myBloggie 2.1.6 allow remote attackers to obtain sensitive information via (1) an invalid year parameter to calendar.php, reached through index.php; (2) a direct request to common.php; and (3) a mode array parameter in the query string to login.php, which reveal the installation path in various error messages.

The vulnerability identified as CVE-2007-3650 affects myWebland myBloggie version 2.1.6, a content management system that suffers from multiple information disclosure flaws. This vulnerability classifies under CWE-200, which represents "Information Exposure," and represents a significant security weakness that can be exploited by remote attackers without authentication. The vulnerability manifests through three distinct attack vectors that collectively expose sensitive system information to unauthorized parties, making it particularly dangerous for web applications that handle user-generated content and require robust security controls.
The primary attack vector involves manipulating the year parameter in calendar.php, which can be accessed through the index.php entry point, allowing attackers to trigger error messages that contain installation path information. The second vector targets common.php through direct requests, while the third involves exploiting the mode array parameter in login.php query strings. All three attack paths result in the disclosure of sensitive information that can be leveraged by threat actors to understand the application's file structure and potentially identify other vulnerabilities. These error messages reveal the physical path where the application is installed, which can include directory structures, file names, and system-specific details that aid in further exploitation attempts.
From an operational impact perspective, this vulnerability enables attackers to gather intelligence about the target system's configuration and deployment environment. The disclosed installation paths can be used to craft more sophisticated attacks, such as directory traversal attempts or exploitation of other vulnerabilities that may exist in the same environment. The information disclosure creates a foundation for advanced persistent threats, as attackers can use the exposed paths to map the application's architecture and identify potential attack surfaces. This type of information exposure significantly reduces the attack surface and provides threat actors with valuable reconnaissance data that would otherwise require extensive manual investigation.
The vulnerability aligns with several tactics described in the MITRE ATT&CK framework, particularly those related to reconnaissance and initial access phases. Attackers can use the exposed installation paths to perform more targeted attacks against the application or the underlying infrastructure. The vulnerability also demonstrates poor input validation practices and inadequate error handling, which are common themes in web application security failures. Organizations should consider implementing proper error handling mechanisms that do not expose sensitive system information and should enforce strict input validation to prevent parameter manipulation attacks. The issue also highlights the importance of secure coding practices and regular security assessments to identify and remediate such information disclosure vulnerabilities before they can be exploited in real-world scenarios.
Mitigation strategies for this vulnerability include implementing comprehensive error handling that does not expose system paths or internal application details to end users, regular input validation and sanitization of all user-supplied parameters, and ensuring that sensitive information is not displayed in error messages. Organizations should also implement proper access controls and authentication mechanisms to prevent unauthorized access to administrative functions. Additionally, regular security updates and patches should be applied to address known vulnerabilities, and application firewalls or intrusion prevention systems can be deployed to detect and block suspicious parameter manipulation attempts. The vulnerability serves as a reminder of the critical importance of secure error handling and the potential consequences of exposing system information to unauthorized parties in web applications.
