Vignette Content Suite 5.0

Vignette StoryServer 5 and Vignette V/5 allows remote attackers to read and modify license information, and cause a denial of service (service halt) by directly accessing the /vgn/license template.

Vignette StoryServer and Vignette V/5 allows remote attackers to obtain sensitive information via a request for the /vgn/style template.

Vignette StoryServer 5 and Vignette V/6 allows remote attackers to execute arbitrary TCL code via (1) an HTTP query or cookie which is processed in the NEEDS command, or (2) an HTTP Referrer that is processed in the VALID_PATHS command.

The default login template (/vgn/login) in Vignette StoryServer 5 and Vignette V/5 generates different responses whether a user exists or not, which allows remote attackers to identify valid usernames via brute force attacks.

Multiple Cross Site Scripting (XSS) vulnerabilities in Vignette StoryServer 4 and 5, and Vignette V/5 and V/6, allow remote attackers to insert arbitrary HTML and script via text variables, as demonstrated using the errInfo parameter of the default login template.
