npm find-my-way (npm)

Affected versions

< 8.2.2; 9.0.0

Patched versions

>= 8.2.2; >= 9.0.1

Description

Impact

A bad regular expression is generated any time you have two parameters within a single segment, when adding a - at the end, like /:a-:b-.

Patches

Update to find-my-way v8.2.2 or v9.0.1. or subsequent versions.

Workarounds

No known workarounds.

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

Inefficient Regular Expression Complexity

The product uses a regular expression with an inefficient, possibly exponential worst-case computational complexity that consumes excessive CPU cycles. Learn more on MITRE.
