Description

Planetluc's SignMe 1.5 and earlier contain a flaw that allows remote cross site scripting. Cross-site scripting exists because the application does not validate the "hash" variable upon GET submission. This could allow a user to create a specially crafted URL that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity.
