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.

-- Vendor Response:
Oracle has issued an update to correct this vulnerability. More
