Security Bulletin: IBM Security Network Intrusion Prevention System can be affected by vulnerabilities in Ruby on Rails (CVE-2012-2660, CVE-2012-2694, CVE-2013-0156, CVE-2012-6496, CVE-2012-3424, and CVE-2012-2695)

IBM Security Network Intrusion Prevention System is affected by multiple vulnerabilities reported in Ruby on Rails. These vulnerabilities include multiple SQL injection, code execution, and denial of service vulnerabilities that could be exploited remotely by an attacker with access to the Local Management Interface (LMI).

Vulnerability Details:

The following information was provided by Ruby on Rails. In the case of IBM Security Network Intrusion Prevention System, the Local Management Interface requires single platform authentication specific to the IPS system, notwithstanding the information in the CVSS vectors specified below. Further for each vulnerability identified below, the vulnerability is remotely exploitable and no specialized knowledge is required.

CVE-2013-0155 identified on the affected version of Ruby on Rails has no impact on the Intrusion Prevention System.


CVE ID: CVE-2012-2660

DESCRIPTION:

A remote attacker could send specially-crafted SQL statements using an unspecified parameter, which could allow the attacker to view, add, modify or delete information in the back-end database.

CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/76015 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:P/A:P)


CVE ID: CVE-2012-2694

DESCRIPTION: A remote attacker could send specially-crafted SQL statements to Active Record used in conjunction with parameter parsing from Rack via Action Pack, which could allow the attacker to view, add, modify or delete information in the back-end database.

CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/76255 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:P/A:P)


CVE ID: CVE-2013-0156

DESCRIPTION: Ruby on Rails could allow a remote attacker to execute arbitrary code on the system, caused by multiple errors in the XML parameter parsing code. The XML processor decodes a request as a YAML document or as a Ruby Symbol allowing an attacker to inject SQL commands, inject and execute arbitrary code and cause a denial of service. This will allow the attacker to take full control of the system.

CVSS Base Score: 9.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/81119 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:C/I:C/A:C)


CVE ID: CVE-2013-6496

DESCRIPTION: A remote attacker could send specially-crafted SQL statements to the Active Record component which could allow the attacker to view, add, modify or delete information in the back-end database.

CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/81004 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:P/A:P)



CVE ID: CVE-2012-3424

DESCRIPTION: By sending specially-crafted data to the Action Pack digest authentication (authenticate_or_request_with_http_digest), an attacker could exploit this to cause the system to crash.

CVSS Base Score: 5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/77240 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)


CVE ID: CVE-2012-2695

DESCRIPTION: A remote attacker could send specially-crafted SQL statements to the Active Record interface using nested query parameters, which could allow the attacker to view, add, modify or delete information in the back-end database.

CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/76260 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:P/A:P)
