Advisory Content (Page 1 of 3)[ 1 ] [ 2 ] [ 3 ]

Description:
Some vulnerabilities have been reported in vBulletin, which can be exploited by malicious people to conduct cross-site scripting and script insertion attacks.

1) Some unspecified input isn't properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

2) An input validation error in the attachment handling can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site by uploading a specially crafted PDF document containing embedded HTML and script code.

Successful exploitation requires that the malicious PDF document is accessed directly in the Microsoft Internet Explorer browser.

3) An error in the restriction of accessing global.php directly can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site by URL encoding the global.php filename in the URL and setting certain parameters.
