CVE-2006-2329 in AngelineCMS
Summary
by MITRE
AngelineCMS 0.6.5 and earlier allow remote attackers to obtain sensitive information via a direct request for (1) adodb-access.inc.php, (2) adodb-ado.inc.php, (3) adodb-ado_access.inc, (4) adodb-ado_mssql.inc.php, (5) adodb-borland_ibase, (6) adodb-csv.inc.php, (7) adodb-db2.inc.php, (8) adodb-fbsql.inc.php, (9) adodb-firebird.inc.php, (10) adodb-ibase.inc.php, (11) adodb-informix.inc.php, (12) adodb-informix72.inc, (13) adodb-mssql.inc.php, (14) adodb-mssqlpo.inc.php, (15) adodb-mysql.inc.php, (16) adodb-mysqlt.inc.php, (17) adodb-oci8.inc.php, (18) adodb-oci805.inc.php, (19) adodb-oci8po.inc.php, and (20) adodb-odbc.inc.php, which reveal the path in various error messages; and via a direct request for the (21) lib/system/ directory and (22) possibly other lib/ directories, which provide a directory listing and "architecture view."

This vulnerability affects AngelineCMS versions 0.6.5 and earlier, presenting a critical information disclosure flaw that exposes sensitive system details to remote attackers. The vulnerability stems from the application's improper handling of direct requests to various database abstraction layer files and system directories, creating pathways for attackers to gather critical system information. The affected files include multiple adodb database driver implementations that contain error messages revealing system paths, while directory listings expose the application's internal architecture and file structure.
The technical flaw resides in the application's lack of proper access controls and input validation mechanisms. When attackers make direct requests to the specified PHP files, the system fails to properly sanitize these inputs, allowing error messages to be displayed that contain absolute system paths and configuration details. Additionally, the exposure of directory listings through requests to lib/system/ and other lib/ directories provides attackers with comprehensive views of the application's file structure and organizational hierarchy. This type of vulnerability aligns with CWE-200, which covers improper exposure of sensitive information, and represents a classic example of information disclosure through inadequate access controls.
The operational impact of this vulnerability is significant as it provides attackers with detailed reconnaissance information that can be used to plan further attacks. The disclosed system paths can reveal the exact installation location, which may aid in exploitation of other vulnerabilities or help attackers understand the system's architecture. Directory listings expose the application's internal structure, potentially revealing the presence of additional sensitive files or directories that should not be publicly accessible. This information can be leveraged for privilege escalation attempts or to identify other potential attack vectors within the system's architecture.
The vulnerability creates multiple attack surfaces that align with ATT&CK technique T1213, which involves data from information repositories, and T1083, which covers file and directory discovery. Attackers can exploit these paths to understand the application's configuration and potentially identify other vulnerabilities in the system. The exposure of database abstraction layer files suggests that attackers might gain insights into the database configuration and potentially exploit weaknesses in database connectivity or access controls. Organizations should implement proper input validation, restrict access to system directories, and ensure that error messages do not reveal sensitive system information to prevent exploitation of this vulnerability.
Mitigation strategies should include implementing proper access controls to prevent direct access to sensitive system files and directories, configuring the web server to disable directory listing capabilities, and ensuring that error messages are properly handled without exposing system paths. The application should be updated to a version that addresses this vulnerability, and administrators should implement proper file permissions and access controls to prevent unauthorized access to system directories. Additionally, regular security audits should be conducted to identify and remediate similar information disclosure vulnerabilities in other parts of the application. The vulnerability demonstrates the importance of proper security configuration and input validation in preventing attackers from gathering reconnaissance information that could lead to more serious security breaches.
