CWE Top 25

CWE Top 25 Testing
for Dangerous Software Weaknesses.

The CWE Top 25 ranks the most dangerous and prevalent software weaknesses behind real-world breaches. QSECS tests your application and codebase against each one, turning abstract weakness classes into concrete, exploitable findings your engineers can fix.

What CWE Top 25 Testing Covers

We evaluate your software for the weakness classes MITRE ranks as the most dangerous, prioritised by real exploitability in your environment.

Where the OWASP Top 10 describes risk categories, the CWE Top 25 names the specific software weaknesses — the coding and design flaws — those risks are built on. It is the language your developers already use to classify and fix defects.

QSECS tests your application and codebase against each weakness class, tracing it from the vulnerable line of code to a working exploit. Every finding lands with a precise CWE identifier, so remediation is unambiguous and verifiable.

What We Test

Memory-safety and input-handling weaknesses such as out-of-bounds access, buffer issues and improper validation

Injection-class weaknesses (CWE-79, CWE-89, CWE-78) traced from source to sink in your code

Improper authentication, authorization and credential-management weaknesses

Insecure deserialization, SSRF and path-traversal weaknesses across services and integrations

Use of components with known vulnerabilities and unsafe default configurations

The Quantum Clock Is Ticking

Security experts estimate quantum computers capable of breaking RSA-2048 encryption could arrive by 2030-2035. Adversaries are already running "Harvest Now, Decrypt Later" campaigns — collecting encrypted data today to decrypt the moment quantum hardware matures. Every test we run is framed by that post-quantum reality, not just today's threats.

Our Approach

How QSECS Tests the CWE Top 25

We combine code-aware analysis with hands-on exploitation so each weakness is confirmed, not just flagged.

We map findings to precise CWE identifiers, giving developers an unambiguous, standards-aligned defect to fix

We trace each weakness from the vulnerable code path to a working proof of concept against the running application

We prioritise by real-world exploitability and business impact rather than raw weakness counts

We deliver Generative AI-supported remediation with secure-coding patterns specific to your language and framework

We verify fixes on retest to ensure the underlying weakness class is eliminated, not relocated
