Three Hidden Web Application Vulnerabilities You Need to Know About

In today’s hyper-connected world, web applications are the backbone of many organisations, driving everything from customer engagement to backend operations. Yet, as these applications become more complex, so too do the threats that target them. Relying on yesterday’s security measures is no longer enough. The stakes are too high, and the landscape is evolving at breakneck speed.

Cloudflare’s recently released State of Application Security 2024 report reveals that security teams are struggling to keep up with the risks associated with organisations’ reliance on modern applications—the essential technology behind today’s most widely used sites. The report not only offers a deep dive into the shifting terrain of web security but also reveals some unsettling trends that could catch enterprises off guard.

Among all these findings, three hidden vulnerabilities, in particular, urgently need to be addressed if companies want to stay ahead of the curve and avoid becoming the next headline.

The API Security Vulnerabilities

Application Programming Interfaces (APIs) are the lifeblood of modern web applications, enabling seamless communication between different services. However, many organisations are still relying on outdated security measures, particularly when it comes to securing APIs.

Traditional Web Application Firewall (WAF) rules that employ a “negative security model” are no longer sufficient. This approach assumes that most traffic is harmless and only blocks known threats. However, as API traffic continues to surge, this assumption becomes dangerously flawed.

Instead, what’s needed is a shift to a positive security model, where only explicitly allowed traffic is permitted, and everything else is blocked. This strict approach ensures that only legitimate requests get through, reducing the risk of exposing sensitive data through poorly secured APIs. Despite being widely accepted as the best practice, few organisations have made this switch, leaving their APIs vulnerable to various cyber attacks.

Yet, with the stakes as high as they are, the transition from a negative to a positive security model is no longer optional – it’s imperative.

22 Minutes to Disaster

In the digital arms race between cybercriminals and security professionals, speed is a critical factor. Cloudflare’s State of Application Security 2024 report highlights a chilling statistic; on average, attackers exploit zero-day vulnerabilities just 22 minutes after a Proof-of-Concept (PoC) is made public!

The term “zero-day” refers to vulnerabilities that are unknown to the software vendor and, therefore, have no patches available. The moment a PoC is released, cybercriminals around the world are alerted to a fresh opportunity, setting off a race to exploit the vulnerability before it can be patched.

This 22-minute window leaves organisations with virtually no time to respond, making pre-emptive measures and rapid incident response strategies more crucial than ever. Organisations that are slow to react or that lack the necessary tools to detect and mitigate these threats are at an increased risk of significant breaches!

To keep pace, organisations need to rethink their approach to security. It’s no longer enough to rely on periodic updates and traditional patch management cycles; there needs to be a focus on continuous monitoring, real-time threat intelligence, and automated response systems that can act in those critical first moments after vulnerabilities are discovered.

Cloudflare’s connectivity solutions, for instance, are designed to offer this level of agility, enabling organisations to mitigate zero-day threats almost as soon as they emerge!

The Hidden Risks of Third-Party Scripts

Third-party scripts are the unsung heroes of the web, powering everything from analytics and ads to social media widgets and tracking codes. On the surface, they offer immense value by enhancing website functionality and user experience.

According to Cloudflare’s report, the average organisation uses 47.1 third-party scripts and makes 49.6 outbound connections to third-party resources. These figures highlight the extent to which modern web applications depend on external code to deliver seamless services. However, this heavy reliance on third-party scripts introduces a new set of vulnerabilities that many organisations overlook.

One of the primary risks associated with third-party scripts is supply chain attacks. When you embed third-party code into your website, you are essentially extending your trust to another entity – one that does not adhere to the same rigorous security standards as your own organisation. If a third-party provider is compromised, so too is your website, potentially exposing your users to malicious code that can steal data, deface your site, or hijack user sessions.

In addition to security risks, there are also compliance and liability concerns to consider. Third-party scripts often collect and process user data, which can trigger regulatory obligations under laws like the General Data Protection Regulation (GDPR). If these scripts mishandle data or fail to comply with legal requirements, your organisation could be held liable, even if the fault lies with the third-party provider. With the sheer number of scripts in use, it became difficult to track and manage each one’s compliance status.
