(2) Vulnerability Details:
phpwind web application has a computer cyber security bug problem. It can be exploited by Unvalidated Redirects and Forwards (URL Redirection) attacks. This could allow a user to create a specially crafted URL, that if clicked, would redirect a victim from the intended legitimate web site to an arbitrary web site of the attacker’s choosing. Such attacks are useful as the crafted URL initially appear to be a web page of a trusted site. This could be leveraged to direct an unsuspecting user to a web page containing attacks that target client side software such as a web browser or document rendering programs.
Several other similar products 0-day vulnerabilities have been found by some other bug hunter researchers before. phpwind has patched some of them. The Full Disclosure mailing list is a public forum for detailed discussion of vulnerabilities and exploitation techniques, as well as tools, papers, news, and events of interest to the community. FD differs from other security lists in its open nature and support for researchers’ right to decide how to disclose their own discovered bugs. The full disclosure movement has been credited with forcing vendors to better secure their products and to publicly acknowledge and fix flaws rather than hide them. Vendor legal intimidation and censorship attempts are not tolerated here! It also publishs suggestions, advisories, solutions details related to Open Redirect vulnerabilities and cyber intelligence recommendations.
