In-Reply-To: <20030529052621.31678.qmail () www securityfocus com> The following can be taken as an official response from the vendor: M-Tech Information Technology, Inc. (http://mtechIT.com/) to this "vulnerability:" 1) The actual risk of these issues to production deployments of P-Synch is nil, as users do not normally, or in our experience ever, access P-Synch by clicking a URL on a third-party web server. Cross-site scripting attacks only affect the web browser of users who click a maliciously-constructed URL to a valid application URL, and this mode of attacking user browsers is simply not relevant to a normal P-Synch deployment. Users access P-Synch in one of several ways, none of which expose their browser to cross-site scripting attacks: a) By typing a well known URL, such as "password" in their browser, and relying on the DNS infrastructure of their organization (e.g., password --> password.acme.com --> P-Synch server). b) By triggering transparent password synchronization with a native password change on some system (and where no browser is involved). c) Using an IVR system and telephone (again, no browser). d) By clicking on a link to P-Synch on their corporate Intranet, which is highly unlikely to be compromised by a mangled URL. 2) A fix for both issues has been available to M-Tech customers for some time. Despite extremely low risk, M-Tech was already aware, in particular of the path disclosure issue, and had already resolved it. 3) Path disclosure is trivial in this case. The fact that P-Synch was installed on "C:\Program Files\P-Synch" is hardly sensitive and security through obscurity is obviously a falsehood. The P-Synch application is hardened, and knowledge on the part of an intruder that the software is installed in a given directory, on a machine that should in normal deployments have no filesystem shares or other remote access mechanisms, is meaningless. 4) The contents of the filesystem of the P-Synch server are not affected. For example, issuing a URL such as: http://demobox/demo/psdemo/nph-psf.exe?css=c:\test.dat will simply cause a web browser that follows this link to get an HTML page that includes the text: <style type="text/css" media="all"> @import "c:\test.dat"; </STYLE> The original poster never made an effort to notify M-Tech of the "discovered vulnerability," and does not have a legitimate copy of P-Synch (presumably because he refused to sign a license agreement which many customers and prospects sign daily to get a free evaluation copy of the software). As there are extremely few P-Synch deployments facing the Internet, it is very unlikely that the poster "came across" P-Synch by accident. Customers and prospects are encouraged to contact M-Tech for more detailed information about this issue, and to download patches if they feel the vulnerability is worth addressing.

I had never heard of it so i was curious to poke around on it a bit. Within an hour i found the vulns listed below. Im pretty sure there are other more serious vulns in P-Synch, but they are very picky about who they give thier software to, even an evaluation version. So was not able to test any further. However i encourage any admins running P-Synch to poke around on it, just to be on the safe side. Description ------------------------------------------------------- P-Synch Total Password Management Solution by M-TECH P-Synch is a total password management solution. It is intended to reduce the cost of ownership of password systems, and simultaneously improve the security of password protected systems. This is done through: -Password Synchronization. -Enforcing an enterprise wide password strength policy. -Allowing authenticated users to reset their own forgotten passwords and enable their locked out accounts. -Streamlining help desk call resolution for password resets. P-Synch is available for both internal use, on the corporate Intranet, as well as for the Internet deployment in B2B and B2C applications. http://www.securityfocus.com/products/837 Problems ------------------------------------------------------- All of these problems are simple, self explanatory vulns so, i'm sure the below examples will speak for themselves. Once again this application was NOT thoroughly researced. So anyone with a copy of P-Synch might wanna explore it further.
