description: diag_routes.php in pfSense 2.5.2 allows sed data injection. Authenticated users are intended to be able to view data about the routes set in the firewall. The data is retrieved by executing the netstat utility, and then its output is parsed via the sed utility. Although the common protection mechanisms against command injection (i.e., the usage of the escapeshellarg function for the arguments) are used, it is still possible to inject sed-specific code and write an arbitrary file in an arbitrary location.

FlyteConsole prior to version 0.52.0 is vulnerable to server-side request forgery when FlyteConsole is open to the general internet. An attacker can exploit any user of a vulnerable instance to access the internal metadata server or other unauthenticated URLs. Passing of headers to an unauthorized actor may occur.
|
||||
remediation: FlyteConsole is the web user interface for the Flyte platform. The patch for this issue deletes the entire `cors_proxy`, as this is not required for console anymore. A patch is available in FlyteConsole version 0.52.0. Or, disable FlyteConsole availability on the internet as a workaround.
