Uses of deprecated API can be used to cause DoS in user-facing endpoints

High severity GitHub Reviewed Published Jun 13, 2022 in argoproj/argo-events • Updated Jan 27, 2023

Package

gomod github.com/argoproj/argo-events (Go)

Affected versions

< 1.7.1

Patched versions

1.7.1

Description

Impact

Several HandleRoute endpoints make use of the deprecated ioutil.ReadAll(). ioutil.ReadAll() reads all the data into memory. As such, an attacker who sends a large request to the Argo Events server will be able to crash it and cause denial of service.

Eventsources susceptible to an out-of-memory denial-of-service attack:

  • AWS SNS
  • Bitbucket
  • Bitbucket
  • Gitlab
  • Slack
  • Storagegrid
  • Webhook

Patches

A patch for this vulnerability has been released in the following Argo Events version:

v1.7.1

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.
