"description": "A mitigation bypass technique was recently identified that led to the deployment of a custom webshell tracked as BUSHWALK. Successful exploitation would bypass the initial mitigation provided by Ivanti on Jan. 10, 2024. At this time, Mandiant assesses the mitigation bypass activity is highly targeted, limited, and is distinct from the post-advisory mass exploitation activity. BUSHWALK is written in Perl and is embedded into a legitimate CS file, querymanifest.cgi. BUSHWALK provides a threat actor the ability to execute arbitrary commands or write files to a server. BUSHWALK executes its malicious Perl function, validateVersion, if the web request platform parameter is SafariiOS. It uses Base64 and RC4 to decode and decrypt the threat actor’s payload in the web request’s command parameter.",

It first assigns a string scalar variable to $useCompOnly. Next, it will use the Perl tr operator to transform the string using a character-by-character translation. The key is then Base64-decoded and used to RC4 decrypt the incoming request. Finally, the issued command is executed by calling eval.",

Note that the legitimate categories endpoint only accepts GET requests./nThe web shell employs two methods of accepting commands from an attacker. It first attempts to retrieve the command stored in the value of a cookie named DSID from the current HTTP request. If the cookie is not present or is not of the expected length, it will attempt to decompress zlib data within the request's POST data. Lastly, FRAMESTING will then pass the decrypted POST data into a Python exec() statement to dynamically execute additional Python code./nNote that DSID is also the name of a cookie used by Ivanti Connect Secure appliances for maintaining user VPN sessions.
