Name of the Vulnerable Software and Affected Versions OliveTin versions 3000.2.0 through 3000.16.0

Description OS command injection is possible because the checkShellArgumentSafety() function in service/internal/executor/arguments.go fails to treat regex: custom argument types as unsafe for Shell mode actions. This allows values that pass the typeSafetyCheckRegex to be interpolated by wrapCommandInShell() into an sh -c command string.

Recommendations Update to version 3000.17.0.
