Description
Spring MVC and WebFlux applications are vulnerable to Multipart request smuggling attacks. Affected versions: Spring Framework 7.0.0 through 7.0.7; 6.2.0 through 6.2.18; 6.1.0 through 6.1.27; 5.3.0 through 5.3.48.
A vulnerability allowing multipart request smuggling has been identified in Spring Framework versions 7.0.0 through 7.0.7, 6.2.0 through 6.2.18, 6.1.0 through 6.1.27, and 5.3.0 through 5.3.48. This vulnerability affects applications using Spring MVC or Spring WebFlux that accept multipart requests and are protected by a Web Application Firewall (WAF) or proxy capable of parsing multipart requests and performing content-based checks. Under these conditions, an attacker could craft malicious multipart requests that bypass WAF or proxy defenses.
Users of affected versions should upgrade to the fixed version. The following upgrade options are available: - For Spring Framework 7.0.x, upgrade to 7.0.8 (OSS) or 7.0.7.1 (Commercial). - For Spring Framework 6.2.x, upgrade to 6.2.19 (OSS) or 6.2.18.1 (Commercial). - For Spring Framework 6.1.x, upgrade to 6.1.28 (Commercial). - For Spring Framework 5.3.x, upgrade to 5.3.49 (Commercial).
