Cross-site scripting, commonly referred to as XSS, is an extraordinarily prevalent cyber security threat targeting web applications. XSS is a script injection attack, where an attacker introduces malicious content into a webpage for execution within another user’s browser. This results in horror shows of security attacks, which include stealing data, hijacking sessions, or unauthorized access.
The attack leaves far-reaching consequences, exposing sensitive information and aiding in phishing attacks, revenge against brands, and network security. The risk factor due to XSS attacks is now increasing with the expansion of businesses and individuals using online services. This blog describes the influence of XSS attacks on network security by focusing on various sensitive data leakages, user session hijacking, and the overall trustworthiness of the network. So, stay with us here and keep reading below.
Top 7 Ways Cross-Site Scripting Attack Affects Network Security
Cross-site scripting (XSS) is one of the most prevalent and dangerous cyber threats. XSS attacks occur when malicious scripts invade web pages viewed by other users, often to steal sensitive information, compromise user sessions, or manipulate the Web content. In this case, the repercussions of these attacks can severely compromise the network security, rendering systems vulnerable to a multitude of malicious activities. This blog will highlight the many ways cross-site scripting attack affects network security. So, keep an eye on this page to reveal the notion.
1. Exposes Sensitive Data
The exposure of sensitive user data could be the most serious consequence of an XSS attack. An XSS vulnerability allows an attacker to inject malicious JavaScript code into a site that executes whenever a user interacts with the site. It would execute the theft of any cookies, session tokens, or other relevant data stored in the user’s browser. The attackers would then use this information to impersonate the user and log in to their accounts, methods available to steal data, or manipulate personal information.
For example, if a website has an XSS on its login page, an attacker could inject a script that collects the login credentials entered by users. These credentials are sent to the attacker’s server for malicious purposes, such as account takeover or identity theft. This scenario gets disturbing for organizations as it can include loss of sensitive information, such as username, password, personal identification, and payment details, creating the risk of data breaches, compliance violations, and lawsuits.
2. Hijacks User Sessions
Session hijacking is another extreme effect of an XSS attack. An attacker has compromised an active session of the user by taking over the session on stealing the user’s session cookie. The session cookie, which is associated with the authentication of the user, allows access to the system. Now, in an XSS attack, malicious scripts go into that website, and user session cookies can be culled thereafter through that injection of XSS. By now, the attacker has taken these cookies into impersonating a user as well as using the account to which he or she would have been logged on without password knowledge.
This is particularly more serious when users are logged in to very crucial systems such as online banking access, social networks, or the enterprise. Once the session of the user is hijacked, it can carry out unauthorized operations such as money transfers, password changes, or access to certain confidential information. Damage from session hijacking may be severe since it may incur losses in finances, unauthorized data access, and the possibility of further attacks because compromised credentials can be used for lateral movement within networks.
3. Enables Phishing Attacks
XSS attacks also lead to phishing attacks wherein the victim gets deceived into revealing personal credentials such as login information or financial data. Traditionally, an attacker impersonating a genuine service or site would cause the occurrence through e-mails or fake websites. However, the major difference is that in the case of XSS, a direct injection attack is performed on valid sites. Thus, phishing attempts become more convincing as much authenticity is pushed towards the end.
When a user enters their credentials into this form, it sends the data to the attacker instead of the legitimate site. An attacker could gain unauthorized access to a user’s account or even perform another phishing attempt with this information. XSS will make detection of such phishing attacks near impossible since they now happen on things that a user would take as a trusted site. The increased trustworthiness may lead to higher chances of success in attacks, as well as much bigger damage that could happen to users and organizations.
4. Causes Reputation Damage
In this digital age, a company’s reputation is one of its most treasured assets. A successful XSS attack then reverberates on a brand’s reputation, especially if it results in data loss, compromise of accounts, or loss of trust of customers. If a consumer or user is affected by a breach, their confidence in a company is reduced on grounds of being unable to protect their data; thereby bringing down trust and losing business.
This is so because an XSS attack may end up being leveraged by taking possession of users’ data through theft or manipulation of data, which in turn could cause a backlash in public media and legal hindrance. To get the business established, customers always want security for their data when they relate to a brand.

5. Increases Network Load & Resource Drain
XSS attacks increase network load and resource drain. Network-based attacks might be more to the attackers’ liking- the stealing of sensitive data or session hijacking. While those attacks can be used to initiate more complex attacks needing huge network resources. An attacker could enter a script making the browsers of the users perform intensive calculations, e.g., sending numerous requests to one of its servers or even taking part in a Distributed Denial of Service (DDoS) attack.
In these types of attacks, the scripts steal information or hijack accounts; then they utilize compromised users’ machines to flood the targeted server with requests. It could lead to heavy server performance degradation, accumulate operational costs, and eventually impart service downtime.
Conclusion
Cross-site scripting (XSS) attacks are considered a potential risk to network security, exposing sensitive information, session hijacking, phishing attacks, and tarnishing the organizational reputation and trust for eternity. They exploit these vulnerabilities through web applications that may have adverse financial, legal, and operational consequences in respective organizations. Knowing what the risks entailed with XSS are, organizations can erect barriers to protect themselves and their users against the bane these attacks could bring forth. In such prevention, input validation, cookie handling, and regular security audits will mitigate XSS vulnerabilities from being exploited by malicious actors.
