ZDI-09-058: Oracle Secure Backup Administration Server Authentication Bypass Vulnerability http://www.zerodayinitiative.com/advisories/ZDI-09-058

-- CVE ID: CVE-2009-1977

-- 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. User interaction is not required to exploit this vulnerability.

The specific flaw exists in the logic used to authenticate a user to the administration server running on port 443. The script login.php does not properly sanitize the 'username' variable before using it in a database query. A specially crafted 'username' allows unauthorized attackers to log in with full administrative capabilities.
