MS12-050: Vulnerabilities in SharePoint Could Allow Elevation of Privilege (2695502)
Medium Nessus Plugin ID 59913
Synopsis
The remote host is affected by multiple privilege escalation and information disclosure vulnerabilities.
Description
The versions of InfoPath, Office SharePoint Server, SharePoint Server, Groove Server, Windows SharePoint Services, SharePoint Foundation, or Office Web Apps installed on the remote host are affected by multiple privilege escalation and information disclosure vulnerabilities :
- An information disclosure vulnerability exists in the way that HTML strings are sanitized. An attacker who successfully exploited this vulnerability could perform cross-site scripting attacks and run script in the security context of the logged-on user. (CVE-2012-1858)
- A cross-site scripting and a privilege escalation vulnerability allow attacker-controlled JavaScript to run in the context of the user clicking a link. An anonymous attacker could also potentially issue SharePoint commands in the context of an authenticated user on the site. (CVE-2012-1859)
- An information disclosure vulnerability exists in the way that SharePoint stores search scopes. An attacker could view or tamper with other users' search scopes.
(CVE-2012-1860)
- A cross-site scripting vulnerability exists that allows attacker-controlled JavaScript to run in the context of the user clicking a link. An anonymous attacker could also potentially issue SharePoint commands in the context of an authenticated user. (CVE-2012-1861)
- A URL redirection vulnerability exists in SharePoint.
The vulnerability could lead to spoofing and information disclosure and could allow an attacker to redirect a user to an external URL. (CVE-2012-1862)
- A cross-site scripting vulnerability exists that allows attacker-controlled JavaScript to run in the context of the user clicking a link. An anonymous attacker could also potentially issue SharePoint commands in the context of an authenticated user. (CVE-2012-1863).
