Web Application Vulnerabilities

Evidence

URL	Cookie Name	Evidence
https://www.uob.com.sg/index.html	TSf647e319027	Set-Cookie: TSf647e319027=0802d32c20ab2000cd42036fc5915fc5c205b1dd451bc23de4ae0128d9cb8b801e64db808d470ff508b79517561130003a68a80625979eddd6472b6f19fb68feee6ce2996c2192c44ea2574f37d92f2375d01d7024edfe37eacba7912e8dd551

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.

URL	Cookie Name	Evidence
https://www.uob.com.sg/index.html	TSf647e319027	The server responded with Set-Cookie header(s) that does not specify the HttpOnly flag: Set-Cookie: TSf647e319027=0802d32c20ab2000cd42036fc5915fc5c205b1dd451bc23de4ae0128d9cb8b801e64db808d470ff508b79517561130003a68a80625979eddd6472b6f19fb68feee6ce2996c2192c44ea2574f37d92f2375d01d7024edfe37eacba7912e8dd551

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.

Evidence

URL Evidence

URL	Evidence
https://www.uob.com.sg/index.html	Response headers include the HTTP Content-Security-Policy security header with the following security issues:base-uri: Missing base-uri allows the injection of base tags. They can be used to set the base URL for all relative (script) URLs to an attacker controlled domain. We recommend setting it to 'none' or 'self'. object-src: Missing object-src allows the injection of plugins which can execute JavaScript. We recommend setting it to 'none'. frame-ancestors: Allow only resources downloaded over HTTPS. default-src: The default-src directive should be set as a fall-back when other restrictions have not been specified. script-src: script-src directive is missing. 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'.

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.

Evidence

URL	Evidence
https://www.uob.com.sg/index.html	Response headers do not include the Referrer-Policy HTTP security header as well as the `<meta/>` tag with name 'referrer' is not present in the response.

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.

OWASP Top 10 - 2021	A5 - Security Misconfiguration

Evidence

URL
https://www.uob.com.sg/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).

Classification

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

Evidence

URL
Missing: https://www.uob.com.sg/.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

Evidence

Domain Queried	DNS Record Type	Description	Value
www.uob.com.sg	A	IPv4 address	61.8.33.40
www.uob.com.sg	CAA	Certificate Authority Authorization	0 issue "globalsign.com"
www.uob.com.sg	CNAME	Canonical name	www.uobgroup.com

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.
