The vulnerability is one of several affecting eBay that were recently uncovered and shared with eWEEK by Nir Goldshlager, a researcher with Avnet Information Security Consulting. Among the vulnerabilities are cross-site scripting bugs in the eBay Live Help support page and eBay To Go, which the company fixed by validating user input. In addition, Goldshlager uncovered a blind SQL injection problem in the eBay donations Website.
All of the vulnerabilities have been patched except the CSRF (cross-site request forgery) flaw. According to Chad Greene, eBay's senior manager of global information security, the company has pushed code to the core site to measure the impact of potential fixes for the CSRF problem on the user and will make a decision about how to address the situation in the next three weeks.
