superagent vulnerable to zip bomb attacks

Moderate severity GitHub Reviewed Published Aug 9, 2018 to the GitHub Advisory Database • Updated Sep 8, 2023

Package

npm superagent (npm)

Affected versions

< 3.7.0

Patched versions

3.7.0

Description

Affected versions of superagent do not check the post-decompression size of ZIP compressed HTTP responses prior to decompressing. This results in the package being vulnerable to a ZIP bomb attack, where an extremely small ZIP file becomes many orders of magnitude larger when decompressed.

This may result in unrestrained CPU/Memory/Disk consumption, causing a denial of service condition.

Recommendation

Update to version 3.7.0 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.
