iDefense Security Advisory 01.13.09
http://labs.idefense.com/intelligence/vulnerabilities/ Jan 13, 2009
I. BACKGROUND Oracle Corp.'s Secure Backup is a tape backup management software, for more information, please visit following website: http://www.oracle.com/technology/products/secure-backup/index.html
II. DESCRIPTION Remote exploitation of two command injection vulnerabilities in the authentication component of Oracle Corp.'s Secure Backup Administration Server could allow an unauthenticated attacker to execute arbitrary commands in the context of the running server.
In both cases, the vulnerabilities exist in PHP scripts that authenticate a user attempting to use the service.
The first vulnerability is in "php/login.php". By making a login request with a specially crafted cookie value, an attacker can execute arbitrary code on the server.
The second vulnerability is in "php/common.php". This function is called from the "login.php" page. A variable is used to specify a command to be run. An attacker can supply any shell command for this variable and it will be executed in the context of the web server process.
III. ANALYSIS Exploitation allows an attacker to execute arbitrary shell commands in the context of the web server process. Under Windows, the Administration Server runs as SYSTEM, so the injected command will be executed as SYSTEM. Under Linux it runs as an unprivileged user. No authentication is required to exploit this vulnerability.
IV. DETECTION Oracle Corp.'s Secure Backup version 10.2.0.2 for Linux, and Secure Backup version 10.2.0.2 for Windows have been confirmed vulnerable. Other versions and other platforms may also be affected.
V. WORKAROUND Block access to the httpd interface of vulnerable servers.
