Detailsinfo

A vulnerability classified as problematic has been found in Rocket.Chat up to 4.1.2 on macOS. Affected is some unknown functionality of the component TCC Policy Handler. The manipulation with an unknown input leads to a authorization vulnerability. CWE is classifying the issue as CWE-863. The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check. This allows attackers to bypass intended access restrictions. This is going to have an impact on confidentiality. CVE summarizes:

The macOS Rocket.Chat application is affected by a vulnerability that allows bypassing Transparency, Consent, and Control (TCC) policies, enabling the exploitation or abuse of permissions specified in its entitlements (e.g., microphone, camera, automation, network client). Since Rocket.Chat was not signed with the Hardened Runtime nor set to enforce Library Validation, it is vulnerable to DYLIB injection attacks, which can lead to unauthorized actions or escalation of permissions. Consequently, an attacker gains capabilities that are not permitted by default under the Sandbox and its application profile.

The weakness was presented by Carlos Garrido. This vulnerability is traded as CVE-2024-8270 since 08/28/2024. The exploitability is told to be easy. The attack needs to be approached locally. There are neither technical details nor an exploit publicly available.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
