Vulnerability Details:


The following information was provided by Ruby on Rails. In the case of IBM Security Network Protection, the Local Management Interface is affected. For the vulnerabilities identified below, they are remotely exploitable, no specialized knowledge is required, and authentication is not required.



CVE ID: CVE-2013-1854

DESCRIPTION:

The Active Record component in Ruby on Rails 2.3.x before 2.3.18, 3.1.x before 3.1.12, and 3.2.x before 3.2.13 processes certain queries by converting hash keys to symbols, which allows remote attackers to cause a denial of service via crafted input to a where method. An exploit could impact the availability of the system, but the integrity of data and confidentiality of information are not compromised.

CVSS Base Score: 5.0
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/82922 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-2013-1857

DESCRIPTION: Ruby on Rails is vulnerable to cross-site scripting, caused by improper validation of user-supplied input by the sanitize helper. A remote attacker could exploit this vulnerability using a specially-crafted URL to execute script in a victim's Web browser within the security context of the hosting Web site, once the URL is clicked. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials. An exploit could impact the integrity of data of the system, but the confidentiality of information and the availability are not compromised.


CVSS Base Score: 4.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/82923 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)



CVE ID: CVE-2013-1855

DESCRIPTION: Ruby on Rails is vulnerable to cross-site scripting, caused by improper validation of user-supplied input. A remote attacker could exploit this vulnerability using the sanitize_css method in Action Pack to execute script in a victim's Web browser within the security context of the hosting Web site, once the URL is clicked. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials. An exploit could impact the integrity of data of the system, but the confidentiality of information and the availability are not compromised.

CVSS Base Score: 4.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/82920 for the current score
