Server Side Template Injection in reports

High
whikernel published GHSA-m64w-f7fg-hpcr Apr 25, 2024

Package

iris-web

Affected versions

<= 2.4.5

Patched versions

2.4.6

Description

Impact

Due to an improper setup of Jinja2 environment, reports generation in iris-web is prone to a Server Side Template Injection (SSTI). Successful exploitation of the vulnerability can lead to an arbitrary Remote Code Execution.

An authenticated administrator has to upload a crafted report template containing the payload. Upon generation of a report based on the weaponised report, any user can trigger the vulnerability.

Patches

The vulnerability is patched in IRIS v2.4.6.

Workarounds

No workaround is available. It is recommended to update as soon as possible. Until patching, review the report templates and keep the administrative privileges that include the upload of report templates limited to dedicated users.

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.
