Web Application Vulnerabilities

https://nextcloud.kec.kz/index.php/login	Response headers include the HTTP Content-Security-Policy security header with the following security issues:img-src: img-src directive has an IP-Address as source: 172.23.161.149 (will be ignored by browsers!). form-action: Allow only resources downloaded over HTTPS. frame-ancestors: This directive tells the browser whether you want to allow your site to be framed or not. By preventing a browser from framing your site you can defend against attacks like clickjacking. The recommended value is 'none' or 'self'. form-action: form-action directive has an IP-Address as source: 172.23.161.149 (will be ignored by browsers!). frame-src: frame-src directive has an IP-Address as source: 172.23.161.149 (will be ignored by browsers!). img-src: Allow only resources downloaded over HTTPS. object-src: We recommend restricting object-src to 'none'. frame-ancestors: frame-ancestors directive has an IP-Address as source: 172.23.161.149 (will be ignored by browsers!). frame-src: Allow only resources downloaded over HTTPS. frame-ancestors: Allow only resources downloaded over HTTPS.

Vulnerability description

We noticed that the Content-Security-Policy (CSP) header configured for the web application includes unsafe directives. The CSP header activates a protection mechanism implemented in web browsers which prevents exploitation of Cross-Site Scripting vulnerabilities (XSS) by restricting the sources from which content can be loaded or executed.

Risk description

For example, if the unsafe-inline directive is present in the CSP header, the execution of inline scripts and event handlers is allowed. This can be exploited by an attacker to execute arbitrary JavaScript code in the context of the vulnerable application.

Recommendation

Remove the unsafe values from the directives, adopt nonces or hashes for safer inclusion of inline scripts if they are needed, and explicitly define the sources from which scripts, styles, images or other resources can be loaded.

Classification

CWE	CWE-693
OWASP Top 10 - 2017	A6 - Security Misconfiguration
OWASP Top 10 - 2021	A5 - Security Misconfiguration

Evidence

URL
https://nextcloud.kec.kz/robots.txt

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).

Infrastructure Vulnerabilities

Evidence

Domain Queried	DNS Record Type	Description	Value
nextcloud.kec.kz	A	IPv4 address	79.140.225.132

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.
