Description

DataDog::DogStatsd versions through 0.07 for Perl allow metric injections.

DataDog::DogStatsd does not properly sanitise input, allowing metric injections of data from untrusted sources.

The send_stats method does not remove newlines from metric names ($stat variable), allowing attackers to change the metric name prefix.

The send_stats method does not validate the content of the value ($delta variable), allowing attackers to inject metrics, especially from methods that do not restrict the data type for the value, such as set, gauge, count and histogram.

The send_stats method does not validate the content of the tags, which may contain newlines, pipes and colons that allow metric injections.

Note that the SYNOPSIS shows an example of passing a website form "loginName" parameter as a tag, which is unsafe.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.

Weaknesses

Improper Neutralization of CRLF Sequences ('CRLF Injection')

The product uses CRLF (carriage return line feeds) as a special element, e.g. to separate lines or records, but it does not neutralize or incorrectly neutralizes CRLF sequences from inputs. Learn more on MITRE.
