Remote Code Execution Exploit for Citrix Application Delivery Controller and Citrix Gateway [ CVE-2019-19781 ]
While going through the exploit code I found the /dev/urandom
used give out byte sequence instead of texted output and tr
utility can only work upon text data encoded in UTF-8.
Issue:
Fix:
export LC_CTYPE=C
filenameid=$(cat /dev/urandom | tr -dc 'a-zA-Z0-9' | fold -w 32 | head -n 1);
Simply setting the LC_CTYPE=C
in the environment variable prior to the filenameid
initialisation fixes the issue. Under the hood we are just setting the locale to C
type which avoid any fancy byte sequences.
Anyway Good work done.
Cheers
