In versions 1.11.3 and prior, the middleware functionality in Hoverfly is vulnerable to command injection vulnerability at `/api/v2/hoverfly/middleware` endpoint due to insufficient validation and sanitization in user input. The vulnerability exists in the middleware management API endpoint `/api/v2/hoverfly/middleware`. This issue is born due to combination of three code level flaws: Insufficient Input Validation in middleware.go line 94-96; Unsafe Command Execution in local_middleware.go line 14-19; and Immediate Execution During Testing in hoverfly_service.go line 173. This allows an attacker to gain remote code execution (RCE) on any system running the vulnerable Hoverfly service. Since the input is directly passed to system commands without proper checks, an attacker can upload a malicious payload or directly execute arbitrary commands (including reverse shells) on the host server with the privileges of the Hoverfly process. Commit 17e60a9bc78826deb4b782dca1c1abd3dbe60d40 in version 1.12.0 disables the set middleware API by default, and subsequent changes to documentation make users aware of the security changes of exposing the set middleware API.","title":"Description of the CVE"},{"category":"legal_disclaimer","text":"CSAF 2.0 data is provided by SUSE under the Creative Commons License 4.0 with Attribution (CC-BY-4.0).","title":"Terms of use"}],"publisher":{"category":"vendor","contact_details":"https://www.suse.com/support/security/contact/","name":"SUSE Product Security Team","namespace":"https://www.suse.com/"},"references":[{"category":"external","summary":"CVE-2025-54123","url":"https://www.suse.com/security/cve/CVE-2025-54123"},{"category":"external","summary":"SUSE Security Ratings","url":"https://www.suse.com/support/security/rating/"}],"title":"SUSE CVE CVE-2025-54123","tracking":{"current_release_date":"2025-09-19T23:22:48Z","generator":{"date":"2025-09-19T23:22:48Z","engine":{"name":"cve-database.git:bin/generate-csaf-vex.pl","version":"1"}},"id":"CVE-2025-54123","initial_release_date":"2025-09-19T23:22:48Z","revision_history":[{"date":"2025-09-19T23:22:48Z","number":"2","summary":"Current version"}],"status":"interim","version":"2"}},"product_tree":{"branches":[{"branches":[{"branches":[{"category":"product_name","name":"openSUSE Tumbleweed","product":{"name":"openSUSE Tumbleweed","product_id":"openSUSE Tumbleweed","product_identification_helper":{"cpe":"cpe:/o:opensuse:tumbleweed"}}},{"category":"product_version","name":"govulncheck-vulndb-0.0.20250917T170349-1.1","product":{"name":"govulncheck-vulndb-0.0.20250917T170349-1.1","product_id":"govulncheck-vulndb-0.0.20250917T170349-1.1","product_identification_helper":{"purl":"pkg:rpm/suse/govulncheck-vulndb@0.0.20250917T170349-1.1?upstream=govulncheck-vulndb-0.0.20250917T170349-1.1.src.rpm"}}}],"category":"product_family","name":"SUSE Linux Enterprise"}],"category":"vendor","name":"SUSE"}],"relationships":[{"category":"default_component_of","full_product_name":{"name":"govulncheck-vulndb-0.0.20250917T170349-1.1 as component of openSUSE Tumbleweed","product_id":"openSUSE Tumbleweed:govulncheck-vulndb-0.0.20250917T170349-1.1"},"product_reference":"govulncheck-vulndb-0.0.20250917T170349-1.1","relates_to_product_reference":"openSUSE Tumbleweed"}]},"vulnerabilities":[{"cve":"CVE-2025-54123","ids":[{"system_name":"SUSE CVE Page","text":"https://www.suse.com/security/cve/CVE-2025-54123"}],"notes":[{"category":"general","text":"Hoverfly is an open source API simulation tool.
