Vertical privilege escalation attacks are more alarming to an organization because of the potential to affect other computers and access shares across the network. The above situations are classic examples of horizontal privilege escalations. ![]() Making HTTP cookies tamper-proof with digital certificates, and placing critical information related to cookies on the server side, are viable measures to prevent such exploits. Web servers are key internet-facing components, and since they are prone to web-based attacks, it is imperative to keep them secure and configured accurately. ![]() All this happens while the user is completely unaware of what is going on in the back end. Once this is done, the script runs and collects all information regarding the session and cookies, which it then sends to the hacker's web server instead of to the normal web server that hosts the site. Using XSS, attackers introduce malicious code within a website’s content and simply wait for users to click on the piece of content that contains the script. Cross-site Scripting (XSS)Īnother sophisticated method used for privilege escalation is called cross-site scripting, or XSS. An attacker may easily manipulate or steal this data to impersonate another user by loading the cookie on their browser, thereby tricking the web server into granting them the privileges and permissions of that user. Session identifiers keep vital information such as the session ID, user ID, and user roles. Web servers need to understand which system they are currently communicating with on each subsequent HTTP request. The attacker may tamper with the contents of an HTTP cookie when the session identifier is exchanged between the web server and browser whenever a user logs into the website. A privilege escalation attack can be carried out when a website makes access control decisions based on untrustworthy input returned by the browser. Let’s take a look at a privilege escalation attack in the context of a web server. How are privilege escalations carried out? Privilege escalation in the context of a web-server The following images show where one might find the user account control and application permission settings Intrusion of malware to perform malicious tasks such as keystroke logging.Modified system settings or the creation of new users.Theft of sensitive files and/or extortion.Damaged reputation from leakage of users' private data.What are the risks presented to an enterprise? How are privilege escalations carried out? How to thwart a privilege escalation attack? How can Vulnerability Manager Plus help? What are the risks presented to an enterprise? Then, we'll walk you through how you can safeguard your own network from such exploits. Let's first look at the risks presented by these threats to larger networks in a corporate environment. Vertical escalation occurs when the perpetrator uses a normal user account to gain elevated permissions equal to what an administrator would have. Horizontal escalation occurs when a user gains access to another account within the same range of permissions or privileges. There are essentially two ways that privileges can be escalated: horizontal escalation and vertical escalation. ![]() In either case, escalations are carried out with malicious intent. Privilege escalations also occur when a user tricks systems into granting permissions which are higher than what the application developers or IT admins intended to provide to a normal user account. Let us first examine what a privilege escalation attack is.Ī privilege escalation attack is when a standard user gains access to a different user's account by impersonating that user. This article helps you to understand more about privilege escalation attacks, how they differ from other exploits, and how to mitigate and take a stand against these threats.
