Configuration entry injection via unsanitized path input
Published Jun 23, 2023 · Updated Nov 27, 2024
Configuration injection in Haibao Tang JCVI 1.3.5 and earlier allows attackers to add entries to the ~/.jcvirc file via path input. The getpath() function passes stripped console input to RawConfigParser.set() without validation and later writes the resulting configuration to ~/.jcvirc. Command execution requires another code path to interpolate an injected value into a shell command; the demonstrated direct effect is persistent configuration modification.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
