Add security rules for cookie settings and XML processing in YAML config #66
Conversation
WalkthroughThis pull request introduces new security rules in YAML configuration files for Java applications, focusing on cookie security and XML processing. It adds rules to detect insecure cookie settings and to manage DOCTYPE declarations in XML parsing, both categorized with a severity level of "warning." Additionally, corresponding test cases and snapshots are created to validate these rules, ensuring that the application adheres to secure coding practices. Changes

14-19: Enhance security referencesThe security note section could be strengthened by:
- Fixing the typo in "mproper" to "Improper" for CWE-611
- Adding specific CVE references for real-world XXE vulnerabilities
- Including a link to the OWASP XXE Prevention Cheat Sheet
- [CWE-611]: mproper Restriction of XML External Entity Reference + [CWE-611]: Improper Restriction of XML External Entity Reference [OWASP A04:2017]: XML External Entities (XXE) [OWASP A05:2021 - Security Misconfiguration] [REFERENCES] https://blog.sonarsource.com/secure-xml-processor https://xerces.apache.org/xerces2-j/features.html + https://cheatsheetseries.owasp.org/cheatsheets/XML_External_Entity_Prevention_Cheat_Sheet.html + https://cve.mitre.org/cgi-bin/cvekey.cgi?keyword=XXE+Javatests/java/documentbuilderfactory-disallow-doctype-decl-false-java-test.yml (2)
2-40: Enhance test coverage with additional scenariosWhile the valid test cases are good, consider adding these scenarios for more comprehensive coverage:
- XMLReader configuration
- Chained builder creation and configuration
- Custom EntityResolver implementation

2-10: Enhance test coverage with additional scenariosWhile the basic cases are covered, consider adding more test scenarios:
Valid cases:
- Setting secure flag through a variable
- Setting secure flag in constructor
- Setting secure flag in builder pattern
Invalid cases:
- Not setting secure flag at all
- Setting secure flag through a false variable
- Setting secure flag to false in different contexts (constructor, builder)

rules/java/security/documentbuilderfactory-disallow-doctype-decl-false-java.yml (1)
20-46: LGTM: Pattern matching logic is robust
The utility section correctly identifies the dangerous pattern of explicitly setting disallow-doctype-decl to false. The pattern matching is comprehensive and will catch both direct and chained method calls.
tests/java/documentbuilderfactory-disallow-doctype-decl-false-java-test.yml (1)
41-51: LGTM: Invalid test cases cover the core scenarios
The invalid test cases appropriately verify that setting disallow-doctype-decl to false is caught for both DocumentBuilderFactory and SAXParserFactory.
rules/java/security/cookie-secure-flag-false-java.yml (1)
4-12: LGTM! Clear and well-documented message
The message and documentation are clear, actionable, and include relevant security references (CWE-614 and OWASP).
tests/__snapshots__/cookie-secure-flag-false-java-snapshot.yml (1)
1-9: LGTM! Snapshot correctly captures the test case
The snapshot format is correct and properly labels the source code segment.
