Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Fake the Source of Data An adversary provides data under a falsified identity. The purpose of using the falsified identity may be to prevent traceability of the provided data or it might be an attempt by the adversary to assume the rights granted to another identity. One of the simplest forms of this attack would be the creation of an email message with a modified "From" field in order to appear that the message was sent from someone other than the actual sender. Results of the attack vary depending on the details of the attack, but common results include privilege escalation, obfuscation of other attacks, and data corruption/manipulation.

NASL family CGI abuses NASL id DRUPAL_7_57.NASL description According to its self-reported version, the instance of Drupal running on the remote web server is 7.x prior to 7.57. It is, therefore, affected by multiple vulnerabilities : - A flaw exists with the Drupal.checkPlain() function due to improper handling of HTML injection. A remote attacker, with a specially crafted request, could potentially execute arbitrary script code within the trust relationship between the browser and server. (CVE-2017-6927) - A flaw exists with the private file system due to improper checking of permissions when modules provided conflicting access. A remote attacker could potentially access sensitive files. (CVE-2017-6928) - A flaw exists with the bundled jQuery due to improper handling of Ajax requests. A remote attacker, with a specially crafted request, could potentially execute arbitrary script code within the trust relationship between the browser and server. (CVE-2017-6929) - A flaw exists with the language switcher block due to improper validation of user input. A context-dependent attacker, with a specially crafted link, could redirect a user to a malicious site.
