Add security rules for detecting plaintext HTTP links and unencrypted sockets #133
Conversation
WalkthroughThis pull request introduces two new security-focused rules: one for detecting plaintext HTTP links in HTML and another for identifying unencrypted socket connections in Java. The changes include creating corresponding rule definitions, test configurations, and snapshot files to validate the new security checks. These additions aim to enhance code security by flagging potential vulnerabilities related to insecure network communications and link protocols. Changes

9-23: LGTM! Thorough coverage of invalid cases.The invalid test cases comprehensively cover:
- Different quote styles (double, single, unquoted)
- Links with additional attributes
- Case sensitivity (HTTP vs http)
Fix trailing spaces in the file.
Remove trailing spaces from lines 12, 14, 16, 18, 20, and 22 to address the yamllint warnings.

1-10: Enhance rule metadata for better clarity and accuracy.Consider the following improvements:
- The message could better explain the security implications
- CWE-319 is about cleartext transmission in general. Consider also referencing CWE-650 (Trusting HTTP Permission Methods) for HTML-specific context.
message: >- - "This link points to a plaintext HTTP URL. Prefer an encrypted HTTPS URL if possible." + "This link uses an unencrypted HTTP URL, which could expose sensitive data during transmission. Use HTTPS to ensure secure communication." note: >- [CWE-319] Authentication Bypass by Primary Weakness + [CWE-650] Trusting HTTP Permission Methods [REFERENCES] - https://cwe.mitre.org/data/definitions/319.html + - https://cwe.mitre.org/data/definitions/650.html
44-44: Simplify and strengthen the HTTP URL pattern matching.The current regex pattern
^([Hh][Tt][Tt][Pp]://)could be simplified and made more robust:
- Use case-insensitive flag instead of character classes
- Add validation for common HTTP URL patterns
- regex: ^([Hh][Tt][Tt][Pp]://) + regex: ^(?i)(http://[^\s<>"']+)Also applies to: 79-79
11-11: Fix YAML formatting issues.The static analysis tool identified several formatting issues:
- Trailing spaces on lines 11, 56, 61, 64, and 80
- Inconsistent indentation on lines 31 and 66
- Missing newline at end of file

4-12: Enhance the security context in the message.While the current message explains the risk and solution well, consider adding:
- Examples of sensitive data that could be intercepted (passwords, tokens, etc.)
- Specific attack vectors (man-in-the-middle attacks)
- Additional secure alternatives (TLS configuration best practices)
tests/java/unencrypted-socket-java-test.yml (2)
2-6: Enhance SSL/TLS test coverage in valid cases.Consider adding test cases for:
- Explicit TLS version configuration
- Custom SSLSocketFactory implementations
- Socket upgrade scenarios (from plain to SSL)
7-23: Add more real-world invalid test scenarios.Consider adding test cases for:
- Socket reuse patterns
- Connection pooling scenarios
- Socket wrapper classes
- Factory method patterns

1-58: LGTM! Comprehensive snapshot coverage.The snapshots provide good coverage of various socket creation patterns with accurate label positioning.
Consider adding snapshots for:
- Socket creation through factory methods
- Custom socket wrapper classes
- Connection pooling scenarios

2-8: LGTM! Comprehensive coverage of valid cases.The valid test cases effectively cover HTTPS links, HTTP strings in paths, and JavaScript protocol usage.

15-22: Verify pattern coverage for socket creation.The current patterns might miss some cases:
- Socket creation through factory methods
- Socket creation through reflection
- Socket wrapper classes
Let's verify the coverage:
✅ Verification successful
Current socket creation patterns are sufficient ✅
The verification shows that the current patterns
new Socket($$$)andnew ServerSocket($$$)provide adequate coverage. No evidence was found of alternative socket creation patterns such as factory methods, reflection-based creation, or socket wrapper classes in the codebase.🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash # Search for additional socket creation patterns that might need coverage rg -l "Socket.*create|createSocket|getSocket" | grep -v "test|snapshot" # Search for custom socket wrapper classes ast-grep --pattern 'class $_ extends Socket { $$$ }'Length of output: 220
Script:
#!/bin/bash # Search for reflection-based socket creation and factory patterns rg -l "Socket\.class|SocketFactory|SSLSocketFactory" # Search for general Socket instantiation patterns ast-grep --pattern 'new Socket($$$)' ast-grep --pattern 'new ServerSocket($$$)' # Search for SSL socket patterns rg -l "javax\.net\.ssl"Length of output: 636
