- Weaknesses or misconfigurations in website or web application code that allow attackers to potentially gain control of the site and hosting server, often exploited through automated methods.
- Pose significant threats to eCommerce enterprises, affecting reputation and financial stability by enabling unauthorised access to sensitive data, compromising website integrity.
Web vulnerabilities present a critical challenge in today’s digital landscape, posing substantial risks to organisations across various sectors. These weaknesses in web application code can be exploited by cybercriminals to compromise data integrity, breach security measures, and tarnish reputations. Effective mitigation strategies are essential to safeguarding against these threats and maintaining trust among users and stakeholders alike.

What is web vulnerability?
A website vulnerability is a weakness or misconfiguration in a website or web application code that allows an attacker to gain some level of control of the site and potentially the hosting server. Many vulnerabilities are exploited through automated methods, such as botnets. Cybercriminals develop specialised tools that scour the internet for specific platforms, such as WordPress or Joomla, seeking common and publicly known vulnerabilities. Once identified, these vulnerabilities are exploited to steal data, disseminate malicious content, or inject defacement and spam content into the vulnerable site.
Impact of web vulnerabilities
Website vulnerabilities pose a significant threat to eCommerce businesses, impacting both their reputation and bottom line. When exploited, these vulnerabilities can lead to unauthorised access to sensitive data, compromising the integrity of the entire website. Personal data obtained through a user’s browser can also be exploited to execute malicious scripts, further exacerbating the cybersecurity threat. Website security is not a luxury but a necessity.
Increase in data breaches
In 2023, the global landscape faced a surge in cyber attacks and data breaches, with statistics revealing a staggering 694 reported breaches and over 612.4 million breached records worldwide. Among the notable incidents, the MOVEit breach in May 2023 impacted an estimated 17.5 million individuals, exploiting vulnerabilities in Progress MOVEit software. Affected organisations included prestigious institutions like Johns Hopkins University and the University of Utah.
These breaches underscore the critical need for robust security measures, especially in educational and healthcare sectors, which remain prime targets for cyber criminals.
Management and prevention
Addressing these vulnerabilities enhances a website’s security posture, protecting against malicious exploitation and safeguarding data integrity while maintaining user trust.
Input validation and sanitisation: Validate input against expected formats, data types, and length limits. Sanitise input by removing or escaping characters that could be interpreted as malicious code, such as SQL injection or XSS payloads.
Use parameterised queries: Employ parameterised queries or prepared statements when interacting with databases to prevent SQL injection attacks. Parameterised queries separate SQL logic from user input, ensuring input values are treated as data rather than executable code.
Least privilege principle: Adhere to the principle of least privilege by granting users and processes only the minimum permissions needed for their tasks. Restrict database and file system permissions to prevent unauthorised access and minimise potential security breach impacts.
Security headers:m Configure security headers in your web server settings to bolster browser security and mitigate various attack vectors. Common security headers include Content Security Policy (CSP), Strict-Transport-Security (HSTS), X-Content-Type-Options, X-Frame-Options, and X-XSS-Protection.
Secure authentication and session management: Implement robust authentication mechanisms, such as multi-factor authentication (MFA), strong password policies, and secure session management practices. Utilise industry-standard encryption techniques to protect sensitive data, including passwords and session tokens, during transmission and storage.
Security testing and code review: Regularly conduct security testing, including vulnerability assessments, penetration testing, and code reviews, to detect and rectify potential vulnerabilities in your website and web applications. Automated tools, manual testing, and peer reviews aid in identifying vulnerabilities before they can be exploited.
Incident response plan: Develop and maintain an incident response plan to efficiently address security incidents and data breaches. Define roles, establish communication channels, and outline procedures for containing, investigating, mitigating, and recovering from security incidents in a systematic manner.
Regular security patching: Keep your web server, operating system, web applications, frameworks, libraries, and plugins up to date with the latest security patches and updates. Software vendors frequently discover and fix vulnerabilities, making timely patching essential to address known security issues and minimise exploitation risks.
However, delays in implementing patches may occur due to factors such as the complexity of the software stack and dependencies on third-party components.
