################################################### 01. ### Advisory Information ### Title: Persistent Cross-Site Scripting (XSS) in SpagoBI Date published: 2014-03-01 Date of last update: 2014-03-01 Vendors contacted: Engineering Group Discovered by: Christian Catalano Severity: High 02. ### Vulnerability Information ### CVE reference: CVE-2013-6232 CVSS v2 Base Score: 4 CVSS v2 Vector: (AV:N/AC:L/Au:S/C:N/I:P/A:N) Component/s: SpagoBI Class: Input Manipulation 03. ### Introduction ### SpagoBI[1] is an Open Source Business Intelligence suite, belonging to the free/open source SpagoWorld initiative, founded and supported by Engineering Group[2]. It offers a large range of analytical functions, a highly functional semantic layer often absent in other open source platforms and projects, and a respectable set of advanced data visualization features including geospatial analytics. [3]SpagoBI is released under the Mozilla Public License, allowing its commercial use. SpagoBI is hosted on OW2 Forge[4] managed by OW2 Consortium, an independent open-source software community.

This flaw exists because the application does not validate certain unspecified input before returning it to the user. This may allow an attacker to create a specially crafted request that would execute arbitrary script code in a user's browser within the trust relationship between their browser and the server. 05. ### Technical Description / Proof of Concept Code ### In execution page can be visible a toolbar with various icons useful for the user to perform actions related to the document runs. The user can insert a note about the executed document. The note is associated to the document with relative parameters value and to the user. It can be public or private, so public notes are visible to all users while the private notes are visible only from the user creator. An attacker (a SpagoBI malicious user with a restricted account ) can insert a note with jasvascript code: <object data="javascript:alert('XSS')"></object> and save it in public mode. The code execution happens when the victim (an unaware user) click on annotate document detail. This is not the only way to add malicious code in the SpagoBI web app. 06. ### Business Impact ### Exploitation of the vulnerability requires low privileged application user account but low or medium user interaction. Successful exploitation of the vulnerability results in session hijacking, client-side phishing, client-side external redirects or malware loads and client-side manipulation of the vulnerable module context. 07. ### Systems Affected ### This vulnerability was tested against: SpagoBI 4.0 Older versions are probably affected too, but they were not checked. 08. ### Vendor Information, Solutions and Workarounds ### This issue is fixed in SpagoBI v4.1, which can be downloaded from: http://forge.ow2.org/project/showfiles.php?group_id=204 Fixed by vendor [verified] 09. ### Credits ### This vulnerability has been discovered by: Christian Catalano aka wastasy ch(dot)catalano(at)gmail(dot)com 10. ### Vulnerability History ### October 08th, 2013: Vulnerability identification October 22th, 2013: Vendor notification to [SpagoBI Team] November 05th, 2013: Vendor Response/Feedback from [SpagoBI Team] December 16th, 2013: Vendor Fix/Patch [SpagoBI Team] January 16th, 2014: Fix/Patch Verified March 01st, 2014: Vulnerability disclosure 11. ### Disclaimer ### The information contained within this advisory is supplied "as-is" with no warranties or guarantees of fitness of use or otherwise.
