- Summary
- Deno contains a permission escalation via open of privileged files with missing `--deny` flag
- Details
-
Deno is a JavaScript, TypeScript, and WebAssembly runtime with secure defaults. The Deno sandbox may be unexpectedly weakened by allowing file read/write access to privileged files in various locations on Unix and Windows platforms. For example, reading
/proc/self/environmay provide access equivalent to--allow-env, and writing/proc/self/memmay provide access equivalent to--allow-all. Users who grant read and write access to the entire filesystem may not realize that these access to these files may have additional, unintended consequences. The documentation did not reflect that this practice should be undertaken to increase the strength of the security sandbox. Users who run code with--allow-reador--allow-writemay unexpectedly end up granting additional permissions via file-system operations. Deno 1.43 and above require explicit--allow-allaccess to read or write/etc,/devon unix platform (as well as/procand/syson linux platforms), and any path starting with\\on Windows. - Database specific
