Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Server Side Include (SSI) Injection An attacker can use Server Side Include (SSI) Injection to send code to a web application that then gets executed by the web server. Doing so enables the attacker to achieve similar results to Cross Site Scripting, viz., arbitrary code execution and information disclosure, albeit on a more limited scale, since the SSI directives are nowhere near as powerful as a full-fledged scripting language. Nonetheless, the attacker can conveniently gain access to sensitive files, such as password files, and execute shell commands.
- Cross Zone Scripting An attacker is able to cause a victim to load content into their web-browser that bypasses security zone controls and gain access to increased privileges to execute scripting code or other web objects such as unsigned ActiveX controls or applets. This is a privilege elevation attack targeted at zone-based web-browser security. In a zone-based model, pages belong to one of a set of zones corresponding to the level of privilege assigned to that page. Pages in an untrusted zone would have a lesser level of access to the system and/or be restricted in the types of executable content it was allowed to invoke. In a cross-zone scripting attack, a page that should be assigned to a less privileged zone is granted the privileges of a more trusted zone. This can be accomplished by exploiting bugs in the browser, exploiting incorrect configuration in the zone controls, through a cross-site scripting attack that causes the attackers' content to be treated as coming from a more trusted page, or by leveraging some piece of system functionality that is accessible from both the trusted and less trusted zone. This attack differs from "Restful Privilege Escalation" in that the latter correlates to the inadequate securing of RESTful access methods (such as HTTP DELETE) on the server, while cross-zone scripting attacks the concept of security zones as implemented by a browser.
- Cross Site Scripting through Log Files An attacker may leverage a system weakness where logs are susceptible to log injection to insert scripts into the system's logs. If these logs are later viewed by an administrator through a thin administrative interface and the log data is not properly HTML encoded before being written to the page, the attackers' scripts stored in the log will be executed in the administrative interface with potentially serious consequences. This attack pattern is really a combination of two other attack patterns: log injection and stored cross site scripting.
- Command Line Execution through SQL Injection An attacker uses standard SQL injection methods to inject data into the command line for execution. This could be done directly through misuse of directives such as MSSQL_xp_cmdshell or indirectly through injection of data into the database that would be interpreted as shell commands. Sometime later, an unscrupulous backend application (or could be part of the functionality of the same application) fetches the injected data stored in the database and uses this data as command line arguments without performing proper validation. The malicious data escapes that data plane by spawning new commands to be executed on the host.

The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2014-0472 Benjamin Bach discovered that Django incorrectly handled dotted Python paths when using the reverse() URL resolver function. An attacker able to request a specially crafted view from a Django application could use this issue to cause Django to import arbitrary modules from the Python path, resulting in possible code execution. - CVE-2014-0473 Paul McMillan discovered that Django incorrectly cached certain pages that contained CSRF cookies. A remote attacker could use this flaw to acquire the CSRF token of a different user and bypass intended CSRF protections in a Django application. - CVE-2014-0474 Michael Koziarski discovered that certain Django model field classes did not properly perform type conversion on their arguments, which allows remote attackers to obtain unexpected results. - CVE-2014-1418 Michael Nelson, Natalia Bidart and James Westby discovered that cached data in Django could be served to a different session, or to a user with no session at all. An attacker may use this to retrieve private data or poison caches. - CVE-2014-3730 Peter Kuma and Gavin Wahl discovered that Django incorrectly validated certain malformed URLs from user input. An attacker may use this to cause unexpected redirects. last seen 2020-03-17 modified 2014-05-20 plugin id 74097 published 2014-05-20 reporter This script is Copyright (C) 2014-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/74097 title Debian DSA-2934-1 : python-django - security update NASL family SuSE Local Security Checks NASL id OPENSUSE-2014-542.NASL description Python Django was updated to fix security issues and bugs.

The django.util.http.is_safe_url function in Django 1.4 before 1.4.13, 1.5 before 1.5.8, 1.6 before 1.6.5, and 1.7 before 1.7b4 does not properly validate URLs, which allows remote attackers to conduct open redirect attacks via a malformed URL, as demonstrated by http:\djangoproject.com. (CVE-2014-3730). The django.core.urlresolvers.reverse function in Django before 1.4.11, 1.5.x before 1.5.6, 1.6.x before 1.6.3, and 1.7.x before 1.7 beta 2 allows remote attackers to import and execute arbitrary Python modules by leveraging a view that constructs URLs using user input and a dotted Python path. (CVE-2014-0472). The caching framework in Django before 1.4.11, 1.5.x before 1.5.6, 1.6.x before 1.6.3, and 1.7.x before 1.7 beta 2 reuses a cached CSRF token for all anonymous users, which allows remote attackers to bypass CSRF protections by reading the CSRF cookie for anonymous users (CVE-2014-0473). The (1) FilePathField, (2) GenericIPAddressField, and (3) IPAddressField model field classes in Django before 1.4.11, 1.5.x before 1.5.6, 1.6.x before 1.6.3, and 1.7.x before 1.7 beta 2 do not properly perform type conversion, which allows remote attackers to have unspecified impact and vectors, related to MySQL typecasting. (CVE-2014-0474). The updated packages have been patched to correct these issues. last seen 2020-06-01 modified 2020-06-02 plugin id 74446 published 2014-06-11 reporter This script is Copyright (C) 2014-2019 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/74446 title Mandriva Linux Security Advisory : python-django (MDVSA-2014:113)
