Kerentanan Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection'). Skor CVSS 3.1 9.9 (Critical) menurut github.com.

Deskripsi (NVD)

Semaphore UI is a web interface for managing DevOps tools. Prior to 2.18.17 and 2.19.5-beta2, repository git_url handling passes an attacker-controlled --upload-pack option to CmdGitClient.GetLastRemoteCommitHash through POST /api/project/{id}/repositories and scheduled commit-hash polling, allowing a project Manager or Owner to execute arbitrary OS commands in the Semaphore server process. This issue is fixed in versions 2.18.17 and 2.19.5-beta2.
