July 13, 2010

-- CVSS:
9.7, (AV:N/AC:L/Au:N/C:C/I:C/A:P)

-- Affected Vendors:
Oracle

-- Affected Products:
Oracle Secure Backup

-- Vulnerability Details:
This vulnerability allows remote attackers to bypass authentication on
vulnerable installations of Oracle Secure Backup. Authentication is not
required to exploit this vulnerability.

The specific flaw exists in the handling of user input to the uname
variable of the login.php script running on the administration page of
Oracle Secure Backup. Do to the lack of proper shell metacharacter
filtering it is possible to bypass the login check. Successful
exploitation of this vulnerability allows the attacker to access
sensitive information running on the administration server without
proper credentials.

Oracle has issued an update to correct this vulnerability. More
