Description:
ELOG is vulnerable to cross-site scripting, caused by improper validation of user-supplied input when requesting non-existent files to download. A remote attacker could exploit this vulnerability using an unspecified parameter in a specially-crafted URL to execute script in a victim's Web browser within the security context of the hosting Web site, once the URL is clicked. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.
