TITLE

SAP Crystal Reports JobServer GIOP Request Remote Code Execution Vulnerability

DESCRIPTION

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of SAP Crystal Reports. Authentication is not required to exploit this vulnerability. The specific flaw exists within the JobServer.exe process which listens by default on several TCP ports above 1024. When parsing a GIOP request, the process trusts a user-supplied 32-bit value and allocates a buffer on the heap. The process then proceeds to copy the string following this value from the packet until it finds a NULL byte. By crafting a specifically sized packet a remote attacker can overflow the buffer and gain code execution under the context of the SYSTEM user. SAP Crystal Reports is a powerful, dynamic, and actionable reporting solution that helps you design, navigate, and visualize report presentations, and deliver reports online or by embedding reports into enterprise applications. Failed exploit attempts will likely crash the application. ---------------------------------------------------------------------- Windows Applications Insecure Library Loading The Official, Verified Secunia List: http://secunia.com/advisories/windows_insecure_library_loading/ The list is continuously updated as we confirm the vulnerability reports so check back regularly too see if any of your apps are affected. ---------------------------------------------------------------------- TITLE: SAP Crystal Reports Two Vulnerabilities SECUNIA ADVISORY ID: SA41683 VERIFY ADVISORY: Secunia.com http://secunia.com/advisories/41683/ Customer Area (Credentials Required) https://ca.secunia.com/?page=viewadvisory&vuln_id=41683 RELEASE DATE: 2010-10-16 DISCUSS ADVISORY: http://secunia.com/advisories/41683/#comments AVAILABLE ON SITE AND IN CUSTOMER AREA: * Last Update * Popularity * Comments * Criticality Level * Impact * Where * Solution Status * Operating System / Software * CVE Reference(s) http://secunia.com/advisories/41683/ ONLY AVAILABLE IN CUSTOMER AREA: * Authentication Level * Report Reliability * Secunia PoC * Secunia Analysis * Systems Affected * Approve Distribution * Remediation Status * Secunia CVSS Score * CVSS https://ca.secunia.com/?page=viewadvisory&vuln_id=41683 ONLY AVAILABLE WITH SECUNIA CSI AND SECUNIA PSI: * AUTOMATED SCANNING http://secunia.com/vulnerability_scanning/personal/ http://secunia.com/vulnerability_scanning/corporate/wsus_sccm_3rd_third_party_patching/ DESCRIPTION: Two vulnerabilities have been reported in SAP Crystal Reports, which can be exploited by malicious people to compromise a vulnerable system. 1) A boundary error within CMS.exe when parsing GIOP requests can be exploited to cause a heap-based buffer overflow via a specially crafted packet. 2) A boundary error within JobServer.exe when parsing GIOP requests can be exploited to cause a heap-based buffer overflow via a specially crafted packet. SOLUTION: Apply patch.
