############################################################### ID: S21SEC-017-en Title: Vignette /vgn/legacy/save SQL access Date: 15/03/2003 Status: Vendor contacted and solution available Scope: Execution of SQL SELECT calls Platforms: All Author: rpinuaga Location: http://www.s21sec.com/es/avisos/s21sec-017-en.txt Release: External ############################################################### S 2 1 S E C http://www.s21sec.com Vignette /vgn/legacy/save SQL access About Vignette -------------- Vignette develops Content Management and Application Portal Software. Description of vulnerability ---------------------------- Vignette Software installs by default some help applications under de /vgn web directory. One of this utilities is the Vignette Legacy Tool. This application is accessed through it's main template /vgn/legacy/edit. This template is protected by the [ NEEDS LOGIN ] directive and it's not accesible for unauthenticated users. The problem is that the real job of this application is carried by the /vgn/legacy/save template, which is not protected. The only check that is done is in the RECORD directive. But this check is easyly bypassed. The check only looks for an vgn_creds cookie, but it does not check it's content. So what is only needed to do a succesful query is to put some random value on this cookie. This way it's possible to do a SELECT query, over any SQL table that is accesible from the Vignette user that has access to the database. Affected Versions and platforms ------------------------------- This vulnerability has been tested in Vignette StoryServer 4, StoryServer 5 and Vignette V/5. But it seems that all currently avaliable versions are vulnerable. Solution -------- Insert a [ NEEDS LOGIN ] directive in the top of the source code for the /vgn/legacy/save template. Vignette users should procceed to contact vignette throught the standard channels VOLS etc in order to get a solution.
