Regulation text
Bespoke and custom software used in the cardholder data environment must be developed securely. Software-development processes shall incorporate security considerations from the start of the SDLC, including secure coding training, code review, security testing, and remediation of vulnerabilities discovered. Public-facing web applications are addressed by either pen-testing or a deployed automated solution.

| CWE | Why it persists | Confidence |
|---|---|---|
| CWE-79 | 1. Improper Neutralization of Input (Cross-site Scripting) is a common web application vulnerability. 2. Secure coding training and code review directly address this by enforcing proper input validation and output encoding. | 90% |
| CWE-89 | 1. Improper Neutralization of Special Elements (SQL Injection) is a critical vulnerability. 2. Secure coding practices, including parameterized queries and input sanitization, are fundamental to preventing this weakness. | 90% |
| CWE-20 | 1. Improper Input Validation is a root cause for numerous vulnerabilities. 2. Secure development processes, starting early in the SDLC, prioritize robust input validation to prevent many attack types. | 90% |
| CWE-352 | 1. Cross-Site Request Forgery (CSRF) is a common web application vulnerability. 2. Secure coding guidelines and security testing, including pen-testing, help identify and mitigate CSRF risks. | 80% |
| CWE-502 | 1. Deserialization of Untrusted Data can lead to remote code execution. 2. Secure development practices must include careful handling of deserialization, often identified through code review and security testing. | 80% |
| CWE-287 | 1. Improper Authentication allows unauthorized access to systems. 2. Secure development ensures robust authentication mechanisms are designed, implemented, and tested correctly throughout the software lifecycle. | 80% |
| CWE-611 | 1. Improper Restriction of XML External Entity Reference (XXE) can lead to information disclosure or SSRF. 2. Secure coding practices and security testing identify and prevent XXE vulnerabilities in XML parsers. | 70% |
What SQUR Covers
Web application + API pentesting for OWASP Top 10, business logic flaws, authentication bypass, injection attacks, and other application-layer vulnerabilities. €1,995 per scan, 24-hour turnaround, EU-only data.
What SQUR Does Not Cover
Internal network pentesting, endpoint security testing, physical security assessments, social engineering, or ICT third-party concentration risk reviews. Engage a complementary provider for those scope items.
