A new XSS vulnerability was identified on Paypal.com earlier today, found by d3v1l and disclosed on both Security-Shell and XSSed. The problem is with the parameter sender_country in a transaction called nvpsm.
Earlier today Wesley Kerfoot reported on the Full Disclosure mailing list that a page in the Paypal.com domain is susceptible to a non-persistent reflected cross site scripting attack (XSS). While non-persistent XSS bugs are somewhat common, this is quite serious for a site like PayPal, where user accounts are linked directly to bank accounts, debit, or credit cards and payment can be made to third parties without any additional authentication after user access is gained.
A Romanian hacker has on December 6th identified input validation deficiencies in URL parameter handling leading to security vulnerabilities on a section of the official site of the Pentagon, http://pentagon.afis.osd.mil, the headquarters of the U.S. Department of Defense. The hacker who identifies himself as Ne0h has posted images of the vulnerabilities, which are still active at the time of this blog post, on his blog.
