Netsparker confirmed this vulnerability by analyzing the execution of injected JavaScript.

Permanent XSS (Cross-site Scripting) allows an attacker to execute dynamic scripts (Javascript, VbScript) in the context of the application. This allows several different attack opportunities, mostly hijacking the current session of the user or changing the look of the page by changing the HTML on the fly and to steal the user's credentials. This happens because the input entered by the user has been interpreted by HTML/Javascript/VbScript within the browser.

Permanent means that the attack will be stored in the back-end system. In normal XSS attacks an attack needs to e-mail the victim but in a permanent XSS an attacker can just execute the attack and wait for users to see the affected page. As soon as someone visits the page, the attacker's stored payload will get executed.

XSS targets the users of the application instead of the server. Although this is a limitation, since it only allows attackers to hijack other users' session the attacker might attack an administrator to gain full control over the application.

Impact

Permanent XSS is a dangerous issue that has many exploitation vectors, some of which includes:

Remedy

The issue occurs because the browser interprets the input as active HTML, Javascript or VbScript. To avoid this, all input and output from the application should be filtered. Output should be filtered according to the output format and location. Typically the output location is HTML. Where the output is HTML ensure that all active content is removed prior to its presentation to the server.

Prior to sanitizing user input, ensure you have a pre-defined list of both expected and acceptable characters with which you populate a white-list. This list needs only be defined once and should be used to sanitize and validate all subsequent input.

There are a number of pre-defined, well structured white-list libraries available for many different environments, good examples of these include, OWASP Reform and Microsoft Anti Cross-site Scripting libraries are good examples.

Cookie Not Marked As HttpOnly

Cookie Not Marked As HttpOnly

CONFIRMED

Cookie was not marked as HTTPOnly. HTTPOnly cookies can not be read by client-side scripts therefore marking a cookie as HTTPOnly can provide an additional layer of protection against Cross-site Scripting attacks..

Impact

During a Cross-site Scripting attack an attacker might easily access cookies and hijack the victim's session.

Actions to Take

  1. See the remedy for solution
  2. Consider marking all of the cookies used by the application as HTTPOnly (After these changes javascript code will not able to read cookies.

Remedy

Mark the cookie as HTTPOnly. This will be an extra layer of defence against XSS. However this is not a silver bullet and will not protect the system against Cross-site Scripting attacks. An attacker can use a tool such as XSS Tunnel to bypass HTTPOnly protection.

Apache Coyote Version Disclosure

Apache Coyote Version Disclosure
1 TOTAL
LOW
Netsparker identified that the target web server is disclosing Apache Coyote version in the HTTP response. This information can help an attacker to gain a greater understanding of the systems in use and potentially develop further attacks targeted at the specific version of Apache.

Impact

An attacker can look for specific security vulnerabilities for the version identified in the SERVER header. The attacker can also use this information in conjunction with the other vulnerabilities in the application or the web server.

Remedy

Configure your web server to prevent information leakage from the SERVER header of its HTTP response.
