Description

This security bulletin contains information about 5 vulnerabilities.


1) Missing Authentication for Critical Function (CVE-ID: N/A)

CWE-ID: CWE-306 - Missing Authentication for Critical Function

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to disclose sensitive information.

The vulnerability exists due to missing authentication for a critical function in /modules/forum.php when handling unauthenticated requests to read-only forum modes. A remote attacker can send a specially crafted HTTP GET request with mode parameters to disclose sensitive information.

The issue occurs only when the forum module is configured in login-only mode, and read operations such as cards, list, and topic are exposed without authentication.


2) Cross-site scripting (CVE-ID: N/A)

CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to execute arbitrary JavaScript in the browser of a user who visits a crafted SSO/SAML URL.

The vulnerability exists due to cross-site scripting in the modules/sso/index.php SSO/SAML endpoint when echoing exception messages generated during SAML request processing. A remote attacker can send a specially crafted SSO/SAML request to execute arbitrary JavaScript in the browser of a user who visits a crafted SSO/SAML URL.

Only instances with the SAML SSO feature enabled are vulnerable.


3) Cross-site request forgery (CVE-ID: N/A)

CWE-ID: CWE-352 - Cross-Site Request Forgery (CSRF)

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:N/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote user to cause unauthorized configuration changes.

The vulnerability exists due to cross-site request forgery (CSRF) in modules/category-report/preferences.php when processing state-changing GET requests for Category Report preferences. A remote user can cause an authenticated administrator to visit a crafted URL to cause unauthorized configuration changes.

User interaction is required, and exploitation is possible through top-level cross-site GET navigation when the Category Report module is enabled and at least one configuration exists.


4) Authorization bypass through user-controlled key (CVE-ID: N/A)

CWE-ID: CWE-639 - Authorization Bypass Through User-Controlled Key

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote user to modify other users' list configurations.

The vulnerability exists due to authorization bypass through a user-controlled key in the save_temporary mode of modules/groups-roles/mylist_function.php when processing a user-supplied list_uuid. A remote user can submit a crafted request referencing another user's or a global list UUID to modify other users' list configurations.

Successful exploitation can transfer ownership of the referenced list to the current user and convert a global list into a personal one, causing it to disappear from other users' selectors.


5) Missing Authorization (CVE-ID: N/A)

CWE-ID: CWE-862 - Missing Authorization

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote user to modify or delete roles across organizations.

The vulnerability exists due to improper access control in groups_roles.php and RolesService::save() when handling requests for role management actions using a supplied role UUID. A remote privileged user can send a specially crafted request referencing a role UUID from another organization to modify or delete roles across organizations.

Exploitation requires the role administrator right in one organization and knowledge of a target role UUID belonging to another organization on the same installation.
