Candidate: CAN-2005-0082 URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-0082 Reference: IDEFENSE:20050119 MySQL MaxDB Web Agent Multiple Denial of Service Vulnerabilities Reference: URL:http://www.idefense.com/application/poi/display?id=187&type=vulnerabilities The sapdbwa_GetUserData function in MySQL MaxDB 7.5.0.0, and other versions before 7.5.0.21, allows remote attackers to cause a denial of service (crash) via invalid parameters to the WebDAV handler code, which triggers a null dereference that causes the SAP DB Web Agent to crash.

Regards, Joey ----- Forwarded message from Michael Sutton <[EMAIL PROTECTED]> ----- Subject: iDEFENSE Security Advisory 01.19.05: MySQL MaxDB Web Agent Multiple Denial of Service Vulnerabilities Date: Wed, 19 Jan 2005 16:03:46 -0500 From: Michael Sutton <[EMAIL PROTECTED]> To: bugtraq@securityfocus.com, [EMAIL PROTECTED] X-Folder: [EMAIL PROTECTED] MySQL MaxDB Web Agent Multiple Denial of Service Vulnerabilities iDEFENSE Security Advisory 01.19.05 www.idefense.com/application/poi/display?id=187&type=vulnerabilities January 19, 2005 I. BACKGROUND MaxDB by MySQL is a re-branded and enhanced version of SAP DB, SAP AG's open source database. MaxDB is a heavy-duty, SAP-certified open source database that offers high availability, scalability and a comprehensive feature set. MaxDB complements the MySQL database server, targeted for large mySAP ERP environments and other applications that require maximum enterprise-level database functionality. Further details are available at: http://www.mysql.com/products/maxdb/ II. DESCRIPTION Two remotely exploitable denial of service conditions have been found to exist in MySQL MaxDB and SAP DB Web Agent products. The first vulnerability specifically exists due to a null pointer dereference in the sapdbwa_GetUserData() function. A remote attacker can request the webdav handler code with invalid parameters to cause a null pointer dereference resulting in a crash of SAP DB Web Agent. The second vulnerability is due to insufficient handling of malformed HTTP headers. A remote attacker can submit a HTTP request with invalid headers to cause a denial of service. III. ANALYSIS A remote attacker can send simple HTTP requests to cause MaxDB Web Agent to crash. IV. DETECTION iDEFENSE has confirmed the existence of these vulnerabilities in MySQL MaxDB 7.5.0.0 on Linux and Windows platforms. It is believed that all versions prior to 7.5.0.21 are affected. V. WORKAROUND Employ firewalls, access control lists or other TCP/UDP restriction mechanisms to limit access to administrative systems and services. VI. VENDOR RESPONSE The vulnerability has been addressed in MaxDB 7.5.00.21. Updated binaries (version 7.5.00.23) are available from: http://dev.mysql.com/downloads/maxdb/7.5.00.html VII. CVE INFORMATION The Common Vulnerabilities and Exposures (CVE) project has assigned the following names to these issues: CAN-2005-0081 MySQL MaxDB Web Agent Null HTTP Header Denial of Service Vulnerability CAN-2005-0082 MySQL MaxDB Web Agent GetUserData Denial of Service Vulnerability VIII.
