CVE-2007-0690 in myEvent
Summary
by MITRE
myEvent 1.6 allows remote attackers to obtain sensitive information via (1) a Log In action without a password to login.php, or an invalid (2) view[] or (3) monthno[] parameter to myevent.php, which reveals the path in various error messages.

The vulnerability identified as CVE-2007-0690 affects myEvent 1.6, a web-based event management system that exposes sensitive information through improper error handling mechanisms. This flaw represents a significant security weakness that can be exploited by remote attackers to gain unauthorized access to system information and potentially escalate their privileges within the affected environment. The vulnerability stems from the application's failure to properly validate user inputs and sanitize error messages, creating opportunities for information disclosure that can aid in further exploitation attempts.
The technical implementation of this vulnerability manifests through three distinct attack vectors that collectively enable attackers to extract sensitive path information from the system. The first vector involves attempting a login action through login.php without providing a password, which triggers error messages containing directory paths. The second and third vectors target myevent.php with invalid view[] and monthno[] parameters respectively, both of which produce error responses that inadvertently reveal system file paths. These error messages are particularly dangerous because they contain absolute or relative paths that can provide attackers with detailed knowledge of the application's directory structure and file locations.
This vulnerability directly relates to CWE-200, which defines information exposure through error messages, and aligns with ATT&CK technique T1212, which covers exploitation for credential access through information discovery. The impact of this vulnerability extends beyond simple information disclosure as it provides attackers with critical system layout information that can be leveraged for subsequent attacks. The exposed paths can reveal the application's installation directory, database connection details, and potentially other system configuration information that could be used to craft more sophisticated attacks against the target environment.
The operational implications of this vulnerability are severe for any organization running the affected myEvent 1.6 software, as it creates a persistent information leak that can be exploited by anyone with network access to the application. Attackers can systematically test these parameters to map out the complete directory structure, potentially identifying backup files, configuration files, or other sensitive resources that might contain additional credentials or system information. This information disclosure vulnerability undermines the principle of least privilege and can significantly reduce the security posture of the affected system.
Mitigation strategies for this vulnerability should focus on implementing proper input validation and error handling practices throughout the application. The system must validate all user inputs, particularly those used in parameterized queries or file operations, and sanitize all error messages to prevent the exposure of system paths or internal implementation details. Organizations should implement comprehensive error handling that logs errors internally while displaying generic messages to users. Additionally, the application should be updated to a newer version that addresses these security flaws, as myEvent 1.6 appears to be an outdated version that likely contains additional unpatched vulnerabilities. Regular security audits and input validation testing should be implemented to prevent similar issues from occurring in other components of the system infrastructure.
