Fix CVE-2016-1000027: Upgrade Spring Framework to 6.2.0

[Copilot]

Critical RCE vulnerability in Spring Framework <6.0.0 due to unsafe Java deserialization. Current version 5.3.16 (via Spring Boot 2.5.10) is vulnerable.

Changes

• Upgraded Spring Boot: 2.5.10 → 3.4.0
  • Transitively upgrades org.springframework:spring-web from 5.3.16 to 6.2.0
  • Exceeds CVE remediation requirement of 6.1.21+
• Set Java compatibility to 17 (required for Spring Boot 3.x)

- implementation ("org.springframework.boot:spring-boot-starter-web:2.5.10")
+ implementation ("org.springframework.boot:spring-boot-starter-web:3.4.0")

+java {
+    sourceCompatibility = JavaVersion.VERSION_17
+    targetCompatibility = JavaVersion.VERSION_17
+}

Impact

Major version upgrade with no source code changes required. Application uses minimal Spring features; javax→jakarta namespace migration not applicable.

Note

Code review flagged additional pre-existing CVEs (Log4j 2.14.1, Jackson 2.8.11, Commons FileUpload 1.3.3, Guava 18.0). Out of scope for this fix.

Remediation Plan

Summary

A critical vulnerability (CVE-2016-1000027) exists in Pivotal Spring Framework prior to version 6.0.0, which may allow remote code execution (RCE) if the framework is used for Java deserialization of untrusted data. The risk is present in applications using the vulnerable library org.springframework:spring-web (version 5.3.16) and may be triggered depending on implementation details and authentication requirements.

Risk Assessment

• Severity: CRITICAL (CVSS 9.8)
• Type: Library Vulnerability (Remote Code Execution)
• Source: New Relic, GitHub Dependabot
• Impacted Library: org.springframework:spring-web (Java)
• Current Version: 5.3.16
• Suggested Remediation Version: 6.1.21 or higher
• Affected Entities:
  • AuthenticationService (GUID: MTI5MjIyMzV8QVBNfEFQUExJQ0FUSU9OfDcyNDE5ODI2)
  • InventoryManagementService (GUID: MTI5MjIyMzV8QVBNfEFQUExJQ0FUSU9OfDcyNDI5Mzg5)
  • FuzzyService (GUID: MTI5MjIyMzV8QVBNfEFQUExJQ0FUSU9OfDcyNDMwMjky)
  • UserMappingService (GUID: MTI5MjIyMzV8QVBNfEFQUExJQ0FUSU9OfDcyNDMwMjQy)
  • RoutingService (GUID: MTI5MjIyMzV8QVBNfEFQUExJQ0FUSU9OfDY1OTA0NDU1)

References

• Spring Framework Commit: Enhanced Documentation
• Deprecation of Impacted Classes
• Removal in v6.0.0

Your Task, @copilot

• Analyze the existing codebase for all usages of org.springframework:spring-web.
• Identify and modify the correct, existing file(s) where the vulnerable library is declared (e.g., pom.xml, build.gradle).
• Do NOT generate new files if a relevant source file already exists.
• Modify the existing resource block to upgrade the library to the suggested version and ensure no unsafe deserialization logic remains.
