-- Corsaire Security Advisory -- Title: Verity Ultraseek path disclosure issue Date: 04.01.13 Application: Verity Ultraseek 5.2.1 and prior Environment: Solaris 7, Windows NT, Windows 2000, Redhat Linux Author: Martin O'Neal [martin.oneal@corsaire.com] Audience: Vendor notification Reference: c040113-001 -- Scope -- The aim of this document is to clearly define a vulnerability in the Verity Ultraseek search product, as supplied by Verity Inc. [1], that allows an attacker to disclose the actual path of the server side document root. -- History -- Discovered: 13.01.04 Vendor notified: 14.01.04 Scheduled release: 30.04.04 Verity requested delay due to bug in patch: 30.04.04 Document released: 05.05.04 -- Overview -- The Verity Ultraseek product provides a web-based search solution. In the event of an invalid value being entered, the actual path of the server side document root is disclosed in the error response. -- Analysis -- The Ultraseek product provides its own web server interface, which parses URLs and returns search data based on the users selections. If a document path consisting of a standard device name (NUL, CON, AUX, COM1, COM2 etc) is entered, then the application responds with an error page that contains the actual path of the server side document root. This path can then be used in conjunction with other potential vulnerabilities to attack specific OS and application configuration files. -- Recommendations -- The vendor has released version 5.2.2 of the Ultraseek product, which is reported not to be susceptible to this issue (although this has not been independently verified by Corsaire). -- CVE -- The Common Vulnerabilities and Exposures (CVE) project has assigned the name CAN-2004-0050 to this issue. This is a candidate for inclusion in the CVE list (http://cve.mitre.org), which standardises names for security problems. -- References -- [1] http://www.verity.com -- Revision -- a. Initial release. b. Revised to include clearer device name definition. c. Revised history section. d.
