Improper Handling of Exceptional Conditions in detect-character-encoding
Impact
In detect-character-encoding v0.6.0 and earlier, data matching no charset causes the Node.js process to crash.
Patches
The problem has been patched in detect-character-encoding v0.7.0.
CVSS score
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/RL:O/RC:C
Base Score: 7.5 (High) Temporal Score: 7.2 (High)
Since detect-character-encoding is a library, the scoring is based on the “reasonable worst-case implementation scenario”, namely, accepting data from untrusted sources over a network and passing it directly to detect-character-encoding. Depending on your specific implementation, the vulnerability’s severity in your program may be different.
Proof of concept
printf "\xAA" | curl --request POST --header "Content-Type: application/octet-stream" --data-binary @- http://localhost:3000 crashes the server.
