Moderate severity GitHub Reviewed Published Sep 21, 2022 to the GitHub Advisory Database • Updated Jan 31, 2023

Package

composer microweber/microweber (Composer)

Affected versions

<= 1.3.1

Patched versions

1.3.2

Description

HTML injection attack is closely related to Cross-site Scripting (XSS). HTML injection uses HTML to deface the page. XSS, as the name implies, injects JavaScript into the page. Both attacks exploit insufficient validation of user input. A patch is available on commit f20abf30a1d9c1426c5fb757ac63998dc5b92bfc and is anticipated to be part of version 1.3.2.

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.
