Critical
Molkobain published GHSA-g652-q7cc-7hfc Apr 15, 2024

Package

iTop (SourceForge)

Affected versions

2.7.9, 3.0.3, 3.1.0

Patched versions

2.7.10, 3.0.4, 3.1.1, 3.2.0

Description

Impact

Files from the env-production folder can be retrieved even though they should have restricted access.
Hopefully, there is no sensitive files stored in that folder natively, but there could be from a third-party module.

Patches

The pages/exec.php script has been fixed to limit execution of PHP files only. Other file types won't be retrieved and exposed.

Workarounds

No workaround, any file within env-production folder can be retrieved. But again, there is no sensitive data in that folder natively.

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.
