DLL Injection in kerberos

High severity GitHub Reviewed Published Sep 4, 2020 to the GitHub Advisory Database • Updated Aug 21, 2023

Package

npm kerberos (npm)

Affected versions

< 1.0.0

Patched versions

1.0.0

Description

Version of kerberos prior to 1.0.0 are vulnerable to DLL Injection. The package loads DLLs without specifying a full path. This may allow attackers to create a file with the same name in a folder that precedes the intended file in the DLL path search. Doing so would allow attackers to execute arbitrary code in the machine.

Recommendation

Upgrade to version 1.0.0 or later.

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.
