Cross-site Scripting
Cross-site Scripting
XSS (Cross-site Scripting) allows an attacker to execute a dynamic script (
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 to steal the user's credentials. This happens because the input entered by a user has been interpreted as HTML/Javascript/VbScript by the browser.
XSS targets the users of the application instead of the server. Although this is a limitation, since it allows attackers to hijack other users' session, an attacker might attack an administrator to gain full control over the application.
Impact
There are many different attacks that can be leveraged through the use of XSS, including:
- Hi-jacking users' active session
- Changing the look of the page within the victims browser.
- Mounting a successful phishing attack.
- Intercept data and perform man-in-the-middle attacks.
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 Secure
Cookie Not Marked As Secure
A Cookie was not marked as secure and transmitted over HTTPS. This means the cookie could potentially be stolen by an attacker who can successfully intercept and decrypt the traffic or following a successful MITM (
Man in the middle) attack.
Impact
This cookie will be transmitted over a HTTP connection, therefore if this cookie is important (such as a session cookie) an attacker might intercept it and hijack a victim's session. If the attacker can carry out a MITM attack, he/she can force victim to make a HTTP request to steal the cookie.
Actions to Take
- See the remedy for solution.
- Mark all cookies used within the application as secure. (If the cookie is not related to authentication or does not carry any personal information you do not have to mark it as secure.))
Mark all cookies used within the application as secure.
Required Skills for Successful Exploitation
To exploit this issue, the attacker needs to be able to intercept traffic. This generally requires local access to the web server or victim's network. Attackers need to be understand layer 2, have physical access to systems either as way points for the traffic, or locally (have gained access to) to a system between the victim and the web server.

Open Policy Crossdomain.xml Identified
Netsparker identified Open Policy Crossdomain.xml file.
Impact
Open Policy Crossdomain.xml file allows other SWF files to make HTTP requests to your web server and see its response. This can be used for accessing one time tokens and CSRF nonces to bypass CSRF restrictions.
Configure your Crossdomain.xml to prevent access from everywhere to your domain.

Insecure Transportation Security Protocol (SSLv2) Supported
Insecure Transportation Security Protocol (SSLv2) Supported
Netsparker detected that your web server is configured to support secure communication over an insecure transporation protocol (SSLv2).
SSLv2 is an insecure protocol and has several flaws. Your secure traffic can be observed when you have established it over SSLv2.
Impact
Attackers can perform MITM attacks and observe the encryption traffic beetwen your website and the visitors.
Configure your webserver to disallow using weak ciphers.
For Apache, you should modify the SSLProtocol directive in the httpd.conf.
SSLProtocol -ALL +SSLv3 +TLSv1
For Microsoft IIS, you should make some changes on the system registry.
- Click Start, click Run, type regedt32 or type regedit, and then click OK.
- In Registry Editor, locate the following registry key :
HKey_Local_Machine\System\CurrentControlSet\Control\SecurityProviders \SCHANNEL\Protocols\SSL2\Server
- There may or may not be a DWORD value named 'Enabled'.
- Type 00000000 in Binary Editor to set the value of the new key equal to "0".

Weak Ciphers Detected
Weak Ciphers Detected
Netsparker detected your web server is configured to allow using weak ciphers during secure communication (SSL).
You should allow only strong ciphers on your web server to protect your secure communication with your visitors.
Impact
Attackers can mount brute-force attacks to decrypt your secure communication between your server and the visitors.
Configure your webserver to disallow using weak ciphers.
For Apache, you should modify the SSLCipherSuite directive in the httpd.conf.
SSLCipherSuite ALL:!aNULL:!ADH:!eNULL:!LOW:!EXP:RC4+RSA:+HIGH:+MEDIUM
For Microsoft IIS, you should make some changes to the system registry.

Internal Server Error
Internal Server Error
The Server responded with an HTTP status 500. This indicates that there is a server-side error. Reasons may vary. The behavior should be analysed carefully. If Netsparker is able to find a security issue in the same resource it will report this as a separate vulnerability.
Impact
The impact may vary depending on the condition. Generally this indicates poor coding practices, not enough error checking, sanitization and whitelisting. However there might be a bigger issue such as SQL Injection. If that's the case Netsparker will check for other possible issues and report them separately.
Analyse this issue and review the application code in order to handle unexpected errors, this should be a generic practice which does not disclose further information upon an error. All errors should be handled server side only.

Auto Complete Enabled
Auto Complete Enabled
"Auto Complete" was enabled in one or more of the form fields. These were either "password" fields or important fields such as "Credit Card".
Impact
Data entered in these fields will be cached by the browser. An attacker who can access the victim's browser could steal this information. This is especially important if the application is commonly used in shared computers such as cyber cafes or airport terminals.
Add the attribute autocomplete="off" to the form tag or to individual "input" fields.
Actions to Take
- See the remedy for the solution.
- Find all instances of inputs which store private data and disable autocomplete. Fields which contain data such as "Credit Card" or "CCV" type data should not be cached. You can allow the application to cache usernames and remember passwords, however, in most cases this is not recommended.
- Re-scan the application after addressing the identified issues to ensure that all of the fixes have been applied properly.
Required Skills for Successful Exploitation
Dumping all data from a browser can be fairly easy and there exist a number of automated tools to undertake this. Where the attacker cannot dump the data, he/she could still browse the recently visited websites and activate the auto-complete feature to see previously entered values.

Cookie Not Marked As HttpOnly
Cookie Not Marked As HttpOnly
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
- See the remedy for solution
- Consider marking all of the cookies used by the application as HTTPOnly (After these changes javascript code will not able to read cookies.
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.
