CVE-2022-24863:
vulnerability analysis and mitigation
Overview
CVE-2022-24863 affects http-swagger, an open source wrapper for automatically generating RESTful API documentation with Swagger 2.0. The vulnerability was discovered in versions prior to 1.2.6, where improper handling of HTTP methods could lead to security issues (GitHub Advisory).
Technical details
The vulnerability stems from improper handling of HTTP methods in http-swagger versions before 1.2.6. The issue allows attackers to perform unauthorized operations through non-GET HTTP methods, which could lead to memory exhaustion on the host system (GitHub Advisory, GitHub Commit).
Impact
The vulnerability enables attackers to perform denial of service (DoS) attacks through memory exhaustion on the host system. This could potentially affect the availability of services using the vulnerable versions of http-swagger (GitHub Advisory).
Mitigation and workarounds
Users are advised to upgrade to version 1.2.6 or later. For those unable to upgrade immediately, a workaround is available by restricting the path prefix to only accept GET methods. This can be implemented by using the Methods(http.MethodGet) restriction in the router configuration (GitHub Advisory, GitHub Release).
