Description

Webform Module of Drupal is prone to the following multiple security vulnerabilities: 1. An arbitrary-file-overwrite vulnerability 2. A cross-site scripting vulnerability An attacker may leverage these issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site and write arbitrary files in the context of the user running the affected application. Webform Module of Drupal versions prior to 7.x-3.29 and 7.x-4.21 are vulnerable.

Recommendations

Block external access at the network boundary, unless external parties require service.
If global access isn't needed, filter access to the affected computer at the network boundary. Restricting access to only trusted computers and networks might greatly reduce the likelihood of a successful attack.

Run all software as a nonprivileged user with minimal access rights.
To limit the consequences of a successful exploit, run server processes within a restricted environment using facilities such as chroot or jail.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity. This may indicate exploit attempts or activity that results from successful exploits.

Do not follow links provided by unknown or untrusted sources.
Do not follow links provided by unknown or untrusted sources. Web users should be cautious about following links to websites that are provided by unfamiliar or suspicious sources. Filtering HTML from emails may help remove a possible vector for transmitting malicious links to users.

Set web browser security to disable the execution of script code or active content.
Since exploiting cross-site scripting issues often requires the execution of malicious script code in web clients, consider disabling script code and active content support within a client browser as a way to prevent a successful exploit. Note that this mitigation tactic might adversely affect legitimate websites that rely on the execution of browser-based script code.
