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

Description:
Federico Muttis has reported a vulnerability in vBulletin, which can be exploited by malicious users to conduct script insertion attacks.

Input passed as the subject of a private message is not properly sanitised before being stored. This can be exploited to insert arbitrary HTML and script code, which is executed in a user's browser session in context of an affected site when the malicious data is viewed.

Successful exploitation requires valid user credentials and that "Show New Private Message Notification Pop-Up" is enabled.

The vulnerability is reported in versions 3.7.2 PL1 and 3.6.10 PL3. Prior versions may also be affected.
