Package

composer pimcore/pimcore (Composer)

Affected versions

< 10.5.19

Patched versions

10.5.19

Description

Impact

Since a user with 'report' permission can already write arbitrary SQL queries and given the fact that this endpoint is using the GET method (no CSRF protection), an attacker can inject an arbitrary query by manipulating a user to click on a link.

The impact of this path traversal and arbitrary extension is limited (creation of arbitrary files and
appending data to existing files) but when combined with the SQL Injection, the exported data can be controlled and a webshell can be uploaded. Attackers can use that to execute arbitrary PHP code on the server with the permissions of the webserver.

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

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. Learn more on MITRE.

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Learn more on MITRE.
