Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Subverting Environment Variable Values The attacker directly or indirectly modifies environment variables used by or controlling the target software. The attacker's goal is to cause the target software to deviate from its expected operation in a manner that benefits the attacker.
- Footprinting An attacker engages in probing and exploration activity to identify constituents and properties of the target. Footprinting is a general term to describe a variety of information gathering techniques, often used by attackers in preparation for some attack. It consists of using tools to learn as much as possible about the composition, configuration, and security mechanisms of the targeted application, system or network. Information that might be collected during a footprinting effort could include open ports, applications and their versions, network topology, and similar information. While footprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
- Exploiting Trust in Client (aka Make the Client Invisible) An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
- Browser Fingerprinting An attacker carefully crafts small snippets of Java Script to efficiently detect the type of browser the potential victim is using. Many web-based attacks need prior knowledge of the web browser including the version of browser to ensure successful exploitation of a vulnerability. Having this knowledge allows an attacker to target the victim with attacks that specifically exploit known or zero day weaknesses in the type and version of the browser used by the victim. Automating this process via Java Script as a part of the same delivery system used to exploit the browser is considered more efficient as the attacker can supply a browser fingerprinting method and integrate it with exploit code, all contained in Java Script and in response to the same web page request by the browser.
- Session Credential Falsification through Prediction This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.

NASL family Mandriva Local Security Checks NASL id MANDRIVA_MDVSA-2015-185.NASL description Updated dokuwiki packages fix security vulnerabilities : inc/template.php in DokuWiki before 2014-05-05a only checks for access to the root namespace, which allows remote attackers to access arbitrary images via a media file details ajax call (CVE-2014-8761). The ajax_mediadiff function in DokuWiki before 2014-05-05a allows remote attackers to access arbitrary images via a crafted namespace in the ns parameter (CVE-2014-8762). DokuWiki before 2014-05-05b, when using Active Directory for LDAP authentication, allows remote attackers to bypass authentication via a password starting with a null (\0) character and a valid user name, which triggers an unauthenticated bind (CVE-2014-8763). DokuWiki 2014-05-05a and earlier, when using Active Directory for LDAP authentication, allows remote attackers to bypass authentication via a user name and password starting with a null (\0) character, which triggers an anonymous bind (CVE-2014-8764). dokuwiki-2014-09-29a allows swf (application/x-shockwave-flash) uploads by default. This may be used for Cross-site scripting (XSS) attack which enables attackers to inject client-side script into Web pages viewed by other users. (CVE-2014-9253). The dokuwiki-2014-09-29b hotfix source disables swf uploads by default and fixes the CVE-2014-9253 issue. DokuWiki before 20140929c has a security issue in the ACL plugins remote API component. The plugin failed to check for superuser permissions before executing ACL addition or deletion. This means everybody with permissions to call the XMLRPC API also had permissions to set up their own ACL rules and thus circumventing any existing rules (CVE-2015-2172). DokuWiki before 20140929d is vulnerable to a cross-site scripting (XSS) issue in the user manager.
