Equibase.com HTML Injection
Posted on 04 February 2016
Vulnerability Type: HTML Injection (Possible XSS) Title: Equibase.com HTML Injection Site Description: Equibase.com is the official source for horse racing results, mobile racing data, statistics as well as all other horse racing and thoroughbred racing information. Details: The page http://www.equibase.com/profiles/results.cfm has a parameter called type (e.g. http://www.equibase.com/profiles/Results.cfm?type=Horse) that has a limited set of valid values. The input for this parameter is render unmodified in the output. This allows for reflected HTML injection and content spoofing such as: http://www.equibase.com/profiles/Results.cfm?type=%3Ch1%3E%3Cb%3EAn%20error%20occured.%20%20Please%20visit%20www.badguysite.com%20and%20log%20in%20to%20your%20equibase%20account%20to%20continue.%3C/b%3E%3C/h1%3E Various other HTML tags were accepted and rendered. Some limited filtering did appear to be in place for XSS mitigation, as basic XSS attacks did not work. Since this was not a sanctioned test by the site owner, extensive reflected XSS testing in this parameter was not tested but based on observation the filtering in place did not appear to be sufficient to stop an advanced reflected XSS attack. Vulnerability Severity: Medium Vendor Interaction: Vendor notified on 1/17 with full report. No response received.
