Web Application Vulnerabilities

Evidence

URL	Cookie Name	Evidence
https://www.zendesk.com/help-center-closed/	georedirect	Set-Cookie: georedirect=false

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.

Classification

CWE	CWE-614
OWASP Top 10 - 2017
OWASP Top 10 - 2021

Evidence

URL	Cookie Name	Evidence
https://www.zendesk.com/help-center-closed/	georedirect	The server responded with Set-Cookie header(s) that does not specify the HttpOnly flag: Set-Cookie: georedirect=false

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.

Classification

CWE	CWE-1004
OWASP Top 10 - 2017
OWASP Top 10 - 2021

Evidence

URL	Evidence
https://www.zendesk.com/help-center-closed/	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.

Classification

CWE	CWE-693
OWASP Top 10 - 2017
OWASP Top 10 - 2021

Evidence

URL
Missing: https://www.zendesk.com/.well-known/security.txt

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.

Infrastructure Vulnerabilities

Domain Queried	DNS Record Type	Description	Value
www.zendesk.com	A	IPv4 address	104.18.34.51
www.zendesk.com	A	IPv4 address	172.64.153.205

www.zendesk.com	AAAA	IPv6 address	2606:4700:4400::ac40:99cd
www.zendesk.com	CNAME	Canonical name	www.zendesk.com.cdn.cloudflare.net

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.
