TITLE

StoneTrip Ston3D StandalonePlayer and WebPlayer of system.openURL Arbitrary command execution vulnerability

DESCRIPTION

The system.openURL function in StoneTrip Ston3D StandalonePlayer (aka S3DPlayer StandAlone) 1.6.2.4 and 1.7.0.1 and WebPlayer (aka S3DPlayer Web) 1.6.0.0 allows remote attackers to execute arbitrary commands via shell metacharacters in the first argument (the sURL argument). S3DPlayer Web and Standalone are prone to a remote command-injection vulnerability because they fail to adequately sanitize user-supplied input data. Attackers can exploit this issue to execute arbitrary commands within the context of the affected application. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Core Security Technologies - CoreLabs Advisory http://www.coresecurity.com/corelabs/ StoneTrip S3DPlayers remote command injection 1. *Advisory Information* Title: StoneTrip S3DPlayers remote command injection Advisory ID: CORE-2009-0401 Advisory URL: http://www.coresecurity.com/content/StoneTrip-S3DPlayers Date published: 2009-05-28 Date of last update: 2009-05-28 Vendors contacted: StoneTrip Release mode: User release 2. *Vulnerability Information* Class: Command injection, Client side Remotely Exploitable: Yes Locally Exploitable: No Bugtraq ID: 35105 CVE Name: CVE-2009-1792 3. *Vulnerability Description* Ston3D is a cross-platform technology developed by StoneTrip [1], allowing applications developed with ShiVa product [2] to be run from various media. It is a platform for 3D real time development, specially designed to make games and other real time applications. Ston3D players come in two flavors: 1. Ston3D StandalonePlayer [3], 2. and Ston3D WebPlayer [4], which runs like an extension or plug-in within most popular web browsers. These players are vulnerable to a command injection vulnerability, which can be exploited by malicious remote attackers. The vulnerability is due to the Ston3D scripting language. It provides the function 'system.openURL()' which does not properly sanitize the input before using it. 4. *Vulnerable packages* 4.1. *Win32* . S3DPlayer Web v1.6.0.0 . S3DPlayer StandAlone v1.6.2.4 . S3DPlayer StandAlone v1.7.0.1 4.2. *MacOS* . S3DPlayer Web v1.6.0.0 . S3DPlayer StandAlone v1.6.2.4 4.3. *Linux* . S3DPlayer StandAlone v1.6.2.4 NOTE: Older versions are probably affected too, but they were not checked. 5. *Non-vulnerable packages* By the time this advisory was published, the vendor: 1. had not released patched versions of its products, 2. had not answered the requests made by Core Security for 3 weeks (see Section 9). Please contact StoneTrip for a fix. 6. *Vendor Information, Solutions and Workarounds* The vendor did not provide this information. A possible mitigation action would be to enable MIME type filtering in your IDS/proxies and block S3DPlayer traffic: /----------- application/x-ston3d-stk - -----------/ As a workaround, vulnerable users can also avoid this flaw by disabling the Ston3D Plugin in their web browsers: 6.1. *Mozilla Firefox* 1. Go to the *Tools* menu, and select *Options...* 2. Click on the *Main* tab 3. Click on the *Manage Add-ons...* 4. Disable *Ston3D Plugin* 6.2. *Safari* 1. Go to the *Safari* menu within Safari, and select *Preferences* 2. Click on the *Security * tab 3. Deselect *Enable plug-ins* 6.3. *Internet Explorer* Set the kill bit for control 7508D2BB-F085-45BF-8261-167C6DF4D477 (as explained in http://support.microsoft.com/kb/240797). Please contact StoneTrip for further information, patches and workarounds. 7. *Credits* This vulnerability was discovered and researched by Diego Juarez from Core Security Technologies. 8. *Technical Description / Proof of Concept Code* Ston3D is a cross-platform technology allowing applications developed with ShiVa product [2] to be run from various media, such as a website, CD/DVD or interactive equipment. This technology provides a scripting interface [5] based on the Lua programming language, within this interface the function 'system.openURL' is defined as follows: /----------- Prototype system.openURL(sURL, sTarget) --Call this function to open an URL. - -----------/ In the current implementation, the call 'system.openURL(sURL, sTarget)' with the parameter 'sURL' set as 'file://path/command' will ultimately execute the equivalent of calling /----------- system("open path/command"); - -----------/ By using platform specific delimiter characters this could allow arbitrary code execution in the context of the player.
