ZDI-11-039: BMC PATROL Agent Service Daemon BGS_MULTIPLE_READS Remote Code Execution Vulnerability http://www.zerodayinitiative.com/advisories/ZDI-11-039 February 3, 2011 -- CVSS: 10, (AV:N/AC:L/Au:N/C:C/I:C/A:C) -- Affected Vendors: BMC Software -- Affected Products: BMC Software Patrol -- Vulnerability Details: This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of BMC Patrol Agent. Authentication is not required to exploit this vulnerability. The specific flaw exists within the service daemon which listens by default on TCP port 6768. When processing the BGS_MULTIPLE_READS commands a user-supplied length value is trusted and utilized in reading arbitrary data into a stack buffer. By providing large enough values a remote attacker can abuse this to execute remote code under the context of the SYSTEM user. -- Vendor Response: BMC Software states: BMC Performance Assurance for Servers Versions 7.4.00, 7.4.10, 7.4.15, 7.5.00, 7.5.10 January, 2011 Tracking number QM001683974: Potential vulnerability in network-accessible binary Service Daemon and Manager Daemon BMC Software is alerting users of the following products to a potential problem: - BMC Performance Analysis for Servers, versions 7.4.00 through 7.5.10 - BMC Performance Assurance for Servers, versions 7.4.00 through 7.5.10 - BMC Performance Assurance for Virtual Servers, versions 7.4.00 through 7.5.10 - BMC Performance Analyzer for Servers, versions 7.4.00 through 7.5.10 - BMC Performance Predictor for Servers, versions 7.4.00 through 7.5.10 - BMC Capacity Management Essentials 1.2.00 (7.4.15) This technical bulletin describes a patch that prevents the problem from occurring. If you have any questions about the problem or the patch, contact BMC Software Customer Support at 800 537 1813 (United States or Canada) or call your local support center. BMC Software thanks Manuel Santamarina-Suarez, of the TippingPoint Zero Day Initiative (ZDI), for reporting this issue. Potential vulnerability in network accessible binaries Service Daemon and Manager Daemon BMC Software has identified a potential security exposure in Perform binaries Service Daemon and Manager Daemon, which listen on a network port. (The default port is 6768.) This problem affects all supported versions of these products. This is a remotely exploitable memory corruption that can result in the remote execution of arbitrary code such as the Perform Installation Owner account on UNIX, or the SYSTEM account on Windows. You can correct this issue by downloading and applying the appropriate patch for your operating system and version of these products. -- Disclosure Timeline: 2009-10-27 - Vulnerability reported to vendor 2011-02-03 - Coordinated public release of advisory -- Credit: This vulnerability was discovered by: * Manuel Santamarina-Suarez -- About the Zero Day Initiative (ZDI): Established by TippingPoint, The Zero Day Initiative (ZDI) represents a best-of-breed model for rewarding security researchers for responsibly disclosing discovered vulnerabilities. Researchers interested in getting paid for their security research through the ZDI can find more information and sign-up at: http://www.zerodayinitiative.com The ZDI is unique in how the acquired vulnerability information is used. TippingPoint does not re-sell the vulnerability details or any exploit code. Instead, upon notifying the affected product vendor, TippingPoint provides its customers with zero day protection through its intrusion prevention technology. Explicit details regarding the specifics of the vulnerability are not exposed to any parties until an official vendor patch is publicly available. Furthermore, with the altruistic aim of helping to secure a broader user base, TippingPoint provides this vulnerability information confidentially to security vendors (including competitors) who have a vulnerability protection or mitigation product.
