Онлайн касса – nanokassa.ru Security & Risk Analysis

The Nanokassa v1.0.2 plugin exhibits a generally positive security posture, with no known vulnerabilities (CVEs) or critical taint analysis findings. The absence of known vulnerabilities and the low number of code signals like dangerous functions and external HTTP requests are encouraging. The high percentage of properly escaped output (84%) also suggests good development practices for preventing cross-site scripting (XSS) vulnerabilities.

However, there are areas for improvement. The complete lack of nonce checks on AJAX handlers is a significant concern, potentially exposing the plugin to cross-site request forgery (CSRF) attacks if any AJAX functionality exists but is not explicitly detailed in the attack surface. Furthermore, the statistic indicating 100% of SQL queries are not using prepared statements is a critical security flaw. This widespread use of raw SQL queries without proper sanitization or parameterization opens the door to SQL injection vulnerabilities, allowing attackers to manipulate database queries and potentially access or modify sensitive data.

While the vulnerability history is clean, this can be due to the plugin's age or a lack of historical analysis. The current code analysis reveals a critical weakness in SQL query handling and a potential weakness in AJAX security due to missing nonce checks. The presence of file operations and external HTTP requests, while not inherently insecure, warrants attention to ensure they are handled safely and do not introduce further attack vectors. The plugin demonstrates a commitment to output sanitization but needs to address fundamental security practices related to database interactions and authentication mechanisms.
