Vulnerability description:
Espn.go.com has a cyber security bug problem. It is vulnerable to XSS (Cross Site Scripting) and Dest Redirect Privilege Escalation (Open Redirect) attacks.
Those vulnerabilities are very dangerous. Since they happen at ESPN’s “login” & “register” pages that are credible. Attackers can abuse those links to mislead ESPN’s users. The success rate of attacks may be high.
During the tests, besides the links given above, large number of ESPN’s links are vulnerable to those attacks.
The programming code flaw occurs at “espn.go.com”‘s “login?” & “register” pages with “redirect” parameter, i.e.
Tests were performed on Firefox (33.0) in Ubuntu (14.04) and IE (8.0. 7601) in Windows 8.

“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!” A great many of the fllowing web securities have been published here, Injection, Broken Authentication and Session Management, Cross-Site Scripting (XSS), Insecure Direct Object References, Security Misconfiguration, Sensitive Data Exposure, Missing Function Level Access Control, Cross-Site Request Forgery (CSRF), Using Components with Known Vulnerabilities, Unvalidated Redirects and Forwards. It also publishes suggestions, advisories, solutions details related to XSS and Open Redirect vulnerabilities and cyber intelligence recommendations.
(1) XSS Web Security Vulnerability
XSS 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. Base on Acunetix, exploited XSS is commonly used to achieve the following malicious results
- Identity theft
- Accessing sensitive or restricted information
- Gaining free access to otherwise paid for content
- Spying on user’s web browsing habits
- Altering browser functionality
- Public defamation of an individual or corporation
- Web application defacement
- Denial of Service attacks

(2) Dest Redirect Privilege Escalation Vulnerability Web Security Vulnerability
From OWASP, an open redirect is an application that takes a parameter and redirects a user to the parameter value without any validation. This vulnerability is used in phishing attacks to get users to visit malicious sites without realizing it. 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.
Use one of webpages for the following tests. The webpage address is “https://computerpitch.wordpress.com/“. Suppose that this webpage is malicious.
The vulnerabilities can be attacked without user login. Tests were performed on Microsoft IE (10.0.9200.16750) of Windows 8, Mozilla Firefox (34.0) & Google Chromium 39.0.2171.65-0 ubuntu0.14.04.1.1064 (64-bit) of Ubuntu (14.04)，Apple Safari 6.1.6 of Mac OS X Lion 10.7.
