The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers). An example of a network attack is an attacker causing a denial of service by sending a specially crafted TCP packet across a wide area network (e.g., CVE-2004-0230).
Attack Complexity
Low
AC
The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Privileges Required
High
PR
The attacker requires privileges that provide significant (e.g., administrative) control over the vulnerable system allowing full access to the vulnerable system’s settings and files.
Scope
Unchanged
S
An exploited vulnerability can only affect resources managed by the same security authority. In the case of a vulnerability in a virtualized environment, an exploited vulnerability in one guest instance would not affect neighboring guest instances.
Confidentiality
High
C
There is total information disclosure, resulting in all data on the system being revealed to the attacker, or there is a possibility of the attacker gaining control over confidential data.
Integrity
High
I
There is a total compromise of system integrity. There is a complete loss of system protection, resulting in the attacker being able to modify any file on the target system.
Availability
High
A
There is a total shutdown of the affected resource. The attacker can deny access to the system or data, potentially causing significant loss to the organization.
CVE Number: CVE-2008-1094
Vulnerability: SQL Injection
Risk: Medium
Attack vector: From Remote
Vulnerability Discovered: 16th June 2008
Vendor Notified: 16th June 2008
Advisory Released: 15thDecember 2008
Abstract
Barracuda Networks Spam Firewall is vulnerable to various SQL Injection attacks. When exploited by an authenticated user, the identified vulnerability can lead to Denial of Service, Database Information Disclosure, etc.
Description
The index.cgi resource was identified as being susceptible to SQL Injection attacks.
When filtering user accounts in Users->Account View section, the pattern_x parameter (where x = 0..n) allows inserting arbitrary SQL code once filter_x parameter is set to search_count_equals� value.
/cgi-bin/index.cgi?&user=&password=&et=&auth_type=Local&locale=en_US&realm=&primary_tab=USERS&secondary_tab=
per_user_account_view&boolean_0=boolean_and&filter_0=search_count_equals&pattern_0=if(database() like concat(char(99),char(37)),5,0)
An attacker can exploit this vulnerability by injecting arbitrary SQL code to be executed as part of the SQL query.
