Description
This security bulletin contains information about 4 vulnerabilities.
1) Authorization bypass through user-controlled key (CVE-ID: N/A)
CWE-ID: CWE-639 - Authorization Bypass Through User-Controlled Key
CVSSv4: 7.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote user to disclose sensitive information.
The vulnerability exists due to improper access control in the import handlers for temp_file operations when processing a user-supplied operation_id. A remote user can supply another user's operation_id to read parsed import data and disclose sensitive information.
Exploitation requires access to /index.php?page=import with allow_import enabled, and the victim must have a pending import task.
2) Missing Authorization (CVE-ID: N/A)
CWE-ID: CWE-862 - Missing Authorization
CVSSv4: 7.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N]
The vulnerability allows a remote user to bypass folder-based authorization and create items in unauthorized folders.
The vulnerability exists due to missing authorization in the CSV import pipeline when importing staged rows into an attacker-supplied folder id. A remote user can submit a crafted import request with an arbitrary folderId to bypass folder-based authorization and create items in unauthorized folders.
Exploitation requires access to /index.php?page=import with allow_import enabled and a staged CSV import operation.
3) Incorrect Comparison (CVE-ID: N/A)
CWE-ID: CWE-697 - Incorrect Comparison
CVSSv4: 7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote user to cause a denial of service.
The vulnerability exists due to incorrect comparison in app/sources/admin.queries.php when handling administrative action requests. A remote privileged user can send a specially crafted request to cause a denial of service.
The issue affects 13 administrative switch cases, and the outer page-access gate restricts access to admin users while the inverted inner check blocks those same users from executing the operations.
4) Cross-site scripting (CVE-ID: N/A)
CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVSSv4: 5.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N]
The vulnerability allows a remote user to execute arbitrary script in a victim's browser.
The vulnerability exists due to improper neutralization of input during web page generation in the One-Time View page (`app/core/otv.php`) when rendering a stored item URL field into HTML. A remote user can create an item with a crafted URL and send an OTV link to a victim to execute arbitrary script in a victim's browser.
User interaction is required to open the crafted OTV link, and the feature may be shared with recipients who do not have a TeamPass account.
