Title: SAP DB web-tools Multiple Vulnerabilities
Severity: CRITICAL
Description:
SAP DB is a free open source database server from SAP AG. The product also ships with a 'web-tools' component that may be integrated with an existing web server or run with its own web server.
SAP DB has been prone to multiple vulnerabilities in the web server provided with the software. These issues may cumulatively allow an attacker to gain access to sensitive information, bypass user and administrative level authentication, and execute arbitrary code on a vulnerable host in order to gain unauthorized access.
A directory traversal issue (CAN-2003-0940) has been reported to exist in the 'web-tools' component. The issue may allow a remote attacker to traverse outside the server root directory by using '../' character sequences. The problem exists due to insufficient sanitization of user-supplied data through a URI. It has been reported that the SAP web servers runs in Local SYSTEM context by default on Windows NT/2000/XP Platforms which may allow an attacker to retrieve all files from a vulnerable host.
Another issue (CAN-2003-0941) is reported to be present in the web administration page of web-tools that may allow an attacker to gain administrative access to a system without proper authentication. The problem occurs when a user with access to web-tools request a URL such as 'http://www.example.com/waadmin.wa'. The software does not verify authentication credentials allowing a user to access and modify configuration of different services.
A buffer overflow vulnerability (CAN-2003-0942) has been reported to exist in the web administration component of web-tools due to insufficient bounds checking. This issue occurs when a URL of excessive length is requested. This issue may allow an attacker to execute arbitrary code on a system. This issue may allow an attacker to execute arbitrary code on a system, resulting in full system compromise.
The 'waecho' service of web-tools is also reported to be prone to a buffer overflow vulnerability (CAN-2003-0944) due to insufficient bounds checking. This service is installed as part of the default installation. The issue occurs if an attacker supplies a large number of characters to the 'requestURI' parameter of a URI request to the service. This issue may allow an attacker to execute arbitrary code on a system, resulting in full system compromise.
It has been reported that the 'websql' and 'webdbm' default services may allow an attacker to gain unauthorized access to a database which are not intended to be publicly accessible via web applications. CAN-2003-0943 has been assigned to the default services issues.
Web Database Manager has been reported to a weakness (CAN-2003-0945) due to a improper generation of sessions IDs. It has been reported that sessions IDs are stored in the URL and may not be randomly generated therefore allowing an attacker to gain unauthorized access to sessions.
These issues are currently undergoing further analysis. Where appropriate, individual BIDs will be created to represent new issues and existing BIDs will be updated for previously known issues.
