A vulnerability has been found in Samba up to 3.2.12 (File Transfer Software) and classified as problematic. Affected by this vulnerability is an unknown function of the component Web Administration Tool. The manipulation with an unknown input leads to a cross-site request forgery vulnerability. The CWE definition for the vulnerability is CWE-352. The web application does not, or can not, sufficiently verify whether a well-formed, valid, consistent request was intentionally provided by the user who submitted the request. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

Multiple cross-site request forgery (CSRF) vulnerabilities in the Samba Web Administration Tool (SWAT) in Samba 3.x before 3.5.10 allow remote attackers to hijack the authentication of administrators for requests that (1) shut down daemons, (2) start daemons, (3) add shares, (4) remove shares, (5) add printers, (6) remove printers, (7) add user accounts, or (8) remove user accounts, as demonstrated by certain start, stop, and restart parameters to the status program.

The weakness was published 07/29/2011 by Narendra Shinde with LAC Co., Ltd as Bug 8290 as confirmed bug report (Bugzilla). It is possible to read the advisory at bugzilla.samba.org. This vulnerability is known as CVE-2011-2522 since 06/15/2011. The attack can be launched remotely. The exploitation doesn't need any form of authentication. It demands that the victim is doing some kind of user interaction. Technical details are unknown but a public exploit is available.

A public exploit has been developed by Narendra Shinde and been published even before and not after the advisory. It is possible to download the exploit at exploit-db.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 2 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 75569 (openSUSE Security Update : ldapsmb (openSUSE-SU-2011:0998-1)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family SuSE Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 70063 (Samba SWAT Cross-Site Scripting and Request Forgery Vulnerabilities).
