Web Application Vulnerabilities
Evidence
| URL | Cookie Name | Evidence |
|---|---|---|
| https://www.squarespace.com/ | SS_MID | Set-Cookie: .squarespace.com |
Vulnerability description
We found that the target application sets cookies with a domain scope that is too broad. Specifically, cookies intended for use within a particular application are configured in such a way that they can be accessed by multiple subdomains of the same primary domain.
Risk description
The risk is that a cookie set for example.com may be sent along with the requests sent to dev.example.com, calendar.example.com, hostedsite.example.com. Potentially risky websites under your main domain may access those cookies and use the victim session from the main site.
Recommendation
The `Domain` attribute should be set to the origin host to limit the scope to that particular server. For example if the application resides on server app.mysite.com, then it should be set to `Domain=app.mysite.com`

| https://www.squarespace.com/ | SS_MID | Set-Cookie: SS_MID=9507c31d-a563-479b-aacc-07c3d5551a7c |
Vulnerability description
We found that a cookie has been set without the Secure flag, which means the browser will send it over an unencrypted channel (plain HTTP) if such a request is made. The root cause for this usually revolves around misconfigurations in the code or server settings.
Risk description
The risk exists that an attacker will intercept the clear-text communication between the browser and the server and he will steal the cookie of the user. If this is a session cookie, the attacker could gain unauthorized access to the victim's web session.
Recommendation
Whenever a cookie contains sensitive information or is a session token, then it should always be passed using an encrypted channel. Ensure that the secure flag is set for cookies containing such sensitive information.

Vulnerability description
We found that a cookie has been set without the HttpOnly flag, which means it can be accessed by potentially malicious JavaScript code running inside the web page. The root cause for this usually revolves around misconfigurations in the code or server settings.
Risk description
The risk is that an attacker who injects malicious JavaScript code on the page (e.g. by using an XSS attack) can access the cookie and can send it to another site. In case of a session cookie, this could lead to session hijacking.
Recommendation
Ensure that the HttpOnly flag is set for all cookies.

Vulnerability description
We noticed that the target application is serving mixed content. This occurs when initial HTML is loaded over a secure HTTPS connection, but other resources (such as images, videos, stylesheets, scripts) are loaded over an insecure HTTP connection. This is called mixed content because both HTTP and HTTPS content are being loaded to display the same page, and the initial request was secure over HTTPS.
Risk description
The risk is that the insecurely loaded resources (HTTP) on an otherwise secure page (HTTPS) can be intercepted or manipulated by attackers, potentially leading to eavesdropping or content tampering.
Recommendation
Ensure that all external resources the page references are loaded using HTTPS.

| https://www.squarespace.com/ | Response headers do not include the Referrer-Policy HTTP security header as well as the |
Vulnerability description
We noticed that the target application's server responses lack the Referrer-Policy HTTP header, which controls how much referrer information the browser will send with each request originated from the current web application.
Risk description
The risk is that if a user visits a web page (e.g. "http://example.com/pricing/") and clicks on a link from that page going to e.g. "https://www.google.com", the browser will send to Google the full originating URL in the `Referer` header, assuming the Referrer-Policy header is not set. The originating URL could be considered sensitive information and it could be used for user tracking.
Recommendation
The Referrer-Policy header should be configured on the server side to avoid user tracking and inadvertent information leakage. The value `no-referrer` of this header instructs the browser to omit the Referer header entirely.

Vulnerability description
We noticed that server software and technology details are exposed, potentially aiding attackers in tailoring specific exploits against identified systems and versions.
Risk description
The risk is that an attacker could use this information to mount specific attacks against the identified software type and version.
Recommendation
We recommend you to eliminate the information which permits the identification of software platform, technology, server and operating system: HTTP server headers, HTML meta information, etc.

Evidence
| URL | Evidence |
|---|---|
| https://www.squarespace.com/ | Response does not include the HTTP Content-Security-Policy security header or meta tag |
Vulnerability description
We noticed that the target application lacks the Content-Security-Policy (CSP) header in its HTTP responses. The CSP header is a security measure that instructs web browsers to enforce specific security rules, effectively preventing the exploitation of Cross-Site Scripting (XSS) vulnerabilities.
Risk description
The risk is that if the target application is vulnerable to XSS, lack of this header makes it easily exploitable by attackers.
Recommendation
Configure the Content-Security-Header to be sent with each HTTP response in order to apply the specific policies needed by the application.

Evidence
Vulnerability description
We found the robots.txt on the target server. This file instructs web crawlers what URLs and endpoints of the web application they can visit and crawl. Website administrators often misuse this file while attempting to hide some web pages from the users.
Risk description
There is no particular security risk in having a robots.txt file. However, it's important to note that adding endpoints in it should not be considered a security measure, as this file can be directly accessed and read by anyone.
Recommendation
We recommend you to manually review the entries from robots.txt and remove the ones which lead to sensitive locations in the website (ex. administration panels, configuration files, etc).

Vulnerability description
We have noticed that the target application includes scripts from external domains. This may be problematic as such scripts have the same level of access as the application's own scripts, which means they can interact with application data and perform actions as the current user.
Risk description
The risk is that cross domain file inclusion can lead to a wide variety security breaches if the external scripts are malicious or become compromised.
Recommendation
You do not have any control over what is in that code. Ensure files on the site are loaded from only trusted sources.

Vulnerability description
We noticed that this web application exposes email addresses, which might be unintended. While not inherently a vulnerability, this information could be leveraged in social engineering or spam related activities.
Risk description
The risk is that exposed email addresses within the application could be accessed by unauthorized parties. This could lead to privacy violations, spam, phishing attacks, or other forms of misuse.
Recommendation
Compartmentalize the application to have 'safe' areas where trust boundaries can be unambiguously drawn. Do not allow email addresses to go outside of the trust boundary, and always be careful when interfacing with a compartment outside of the safe area.

Vulnerability description
We have noticed that the server is missing the security.txt file, which is considered a good practice for web security. It provides a standardized way for security researchers and the public to report security vulnerabilities or concerns by outlining the preferred method of contact and reporting procedures.
Risk description
There is no particular risk in not having a security.txt file for your server. However, this file is important because it offers a designated channel for reporting vulnerabilities and security issues.
Recommendation
We recommend you to implement the security.txt file according to the standard, in order to allow researchers or users report any security issues they find, improving the defensive mechanisms of your server.

| www.squarespace.com | A | IPv4 address | 198.185.159.180 |
Risk description
An initial step for an attacker aiming to learn about an organization involves conducting searches on its domain names to uncover DNS records associated with the organization. This strategy aims to amass comprehensive insights into the target domain, enabling the attacker to outline the organization's external digital landscape. This gathered intelligence may subsequently serve as a foundation for launching attacks, including those based on social engineering techniques. DNS records pointing to services or servers that are no longer in use can provide an attacker with an easy entry point into the network.
Recommendation
We recommend reviewing all DNS records associated with the domain and identifying and removing unused or obsolete records.
