Coin Miner – Coin Hive, and CoinImp monero miner Security & Risk Analysis

The "coin-miner" v1.0.0 plugin presents a mixed security posture. On the positive side, it demonstrates good practices by having no known vulnerabilities (CVEs) and a relatively small attack surface with all identified entry points (AJAX handlers) reportedly secured by authentication checks. The absence of taint analysis findings and critical code signals is also encouraging. However, there are significant concerns lurking within the static analysis results. The plugin executes a substantial number of SQL queries (10 total) with 0% utilizing prepared statements, creating a high risk of SQL injection vulnerabilities. Furthermore, while most output is properly escaped, there's still a percentage that is not, which could lead to cross-site scripting (XSS) issues if the unescaped output is user-controllable.

Despite the lack of historical vulnerabilities, the current code base exhibits weaknesses that could be exploited. The SQL query handling is a critical flaw that overshadows the otherwise clean code signals. The vulnerability history shows a clean slate, which is a positive indicator, but it doesn't negate the risks inherent in the current implementation. The plugin's strengths lie in its protected entry points and lack of critical code signals and CVEs. The primary weakness is the lack of prepared statements for all SQL queries.
