Server crash via Elasticsearch certificate file

Mattermost versions 9.5.x <= 9.5.7 and 9.10.x <= 9.10.0 fail to time limit and size limit the CA path file in the ElasticSearch configuration which allows a System Role with access to the Elasticsearch system console to add any file as a CA path field, such as /dev/zero and, after testing the connection, cause the application to crash.

Munged email address used for password resets and notifications

Mattermost versions 9.9.x <= 9.9.1, 9.5.x <= 9.5.7, 9.10.x <= 9.10.0 and 9.8.x <= 9.8.2 fail to ensure that remote/synthetic users cannot create sessions or reset passwords, which allows the munged email addresses, created by shared channels, to be used to receive email notifications and to reset passwords, when they are valid, functional emails.

A SQL injection vulnerability in "/music/ajax.php?action=find_music" in Kashipara Music Management System v1.0 allows an attacker to execute arbitrary SQL commands via the "search" parameter.

A SQL injection vulnerability in "/music/ajax.php?action=login" of Kashipara Music Management System v1.0 allows remote attackers to execute arbitrary SQL commands and bypass Login via the email parameter.

YouDianCMS ydLib.php curl_exec server-side request forgery

A vulnerability has been found in YouDianCMS 7 and classified as critical. Affected by this vulnerability is the function curl_exec of the file /App/Core/Extend/Function/ydLib.php. The manipulation of the argument url leads to server-side request forgery. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. The identifier VDB-273253 was assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.

An Unrestricted file upload vulnerability was found in "/music/ajax.php?action=save_genre" in Kashipara Music Management System v1.0. This allows attackers to execute arbitrary code via uploading a crafted PHP file.

One-click Client-Side Path Traversal Leading to CSRF in User Management admin page

Mattermost versions 9.9.x <= 9.9.1, 9.5.x <= 9.5.7, 9.10.x <= 9.10.0, 9.8.x <= 9.8.2 fail to sanitize user inputs in the frontend that are used for redirection which allows for a one-click client-side path traversal that is leading to CSRF in User Management page of the system console.

An Unrestricted file upload vulnerability was found in "/music/ajax.php?action=signup" of Kashipara Music Management System v1.0, which allows attackers to execute arbitrary code via uploading a crafted PHP file.

An Unrestricted file upload vulnerability was found in "/music/ajax.php?action=save_music" in Kashipara Music Management System v1.0. This allows attackers to execute arbitrary code via uploading a crafted PHP file.

User creation date manipulation in POST /api/v4/users

Mattermost versions 9.9.x <= 9.9.1, 9.5.x <= 9.5.7, 9.10.x <= 9.10.0, 9.8.x <= 9.8.2 fail to restrict the input in POST /api/v4/users which allows a user to manipulate the creation date in POST /api/v4/users tricking the admin into believing their account is much older.

IDOR when marking read a user's channel

Mattermost versions 9.5.x <= 9.5.7, 9.10.x <= 9.10.0 fail to enforce proper access controls which allows any authenticated user, including guests, to mark any channel inside any team as read for any user.

System Role with edit access to permissions can elevate themselves to system admin

Mattermost versions 9.9.x <= 9.9.1, 9.5.x <= 9.5.7, 9.10.x <= 9.10.0 and 9.8.x <= 9.8.2 fail to restrict which roles can promote a user as system admin which allows a System Role with edit access to the permissions section of system console to update their role (e.g. member) to include the `manage_system` permission, effectively becoming a System Admin.

IBM OpenPages information disclosure

IBM OpenPages with Watson 8.3 and 9.0 could allow authenticated users access to sensitive information through improper authorization controls on APIs.

YouDianCMS information disclosure

A vulnerability, which was classified as problematic, has been found in YouDianCMS 7. This issue affects some unknown processing of the file /t.php?action=phpinfo. The manipulation leads to information disclosure. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. The associated identifier of this vulnerability is VDB-273251. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.

Malicious remote can create arbitrary reactions on arbitrary posts

Mattermost versions 9.9.x <= 9.9.0, 9.5.x <= 9.5.6 fail to properly validate synced reactions, when shared channels are enabled, which allows a malicious remote to create arbitrary reactions on arbitrary posts

Existing local user overwritten by malicious remote

Mattermost versions 9.9.x <= 9.9.0, 9.5.x <= 9.5.6, 9.7.x <= 9.7.5, 9.8.x <= 9.8.1 fail to disallow the modification of local users when syncing users in shared channels. which allows a malicious remote to overwrite an existing local user.

Malicious remote can add users to arbitrary teams and channels

Mattermost versions 9.9.x <= 9.9.0, 9.5.x <= 9.5.6, 9.7.x <= 9.7.5 and 9.8.x <= 9.8.1 fail to properly validate that the channel that comes from the sync message is a shared channel, when shared channels are enabled, which allows a malicious remote to add users to arbitrary teams and channels

Malicious remote can invite itself to an arbitrary local channel

Mattermost versions 9.9.x <= 9.9.0, 9.5.x <= 9.5.6, 9.7.x <= 9.7.5 and 9.8.x <= 9.8.1 fail to disallow unsolicited invites to expose access to local channels, when shared channels are enabled, which allows a malicious remote to send an invite with the ID of an existing local channel, and that local channel will then become shared without the consent of the local admin.

Permanently local data deletion by malicious remote

Mattermost versions 9.9.x <= 9.9.0, 9.5.x <= 9.5.6, 9.7.x <= 9.7.5, 9.8.x <= 9.8.1 fail to properly safeguard an error handling which allows a malicious remote to permanently delete local data by abusing dangerous error handling, when share channels were enabled.

Insufficient data validation in Installer in Google Chrome on Windows prior to 128.0.6613.84 allowed a local attacker to perform privilege escalation via a malicious file. (Chromium security severity: Medium)
