(2) Vulnerability Details:

Webs ID web application has a security bug problem. It can be exploited by XSS attacks. This may allow a remote attacker to create a specially crafted request that would execute arbitrary script code in a user’s browser session within the trust relationship between their browser and the server.

Several other Webs ID products 0-day vulnerabilities have been found by some other bug hunter researchers before. Webs ID has patched some of them. Gmane (pronounced “mane”) is an e-mail to news gateway. It allows users to access electronic mailing lists as if they were Usenet newsgroups, and also through a variety of web interfaces. Gmane is an archive; it never expires messages (unless explicitly requested by users). Gmane also supports importing list postings made prior to a list’s inclusion on the service. It has published suggestions, advisories, solutions related to XSS vulnerabilities.
