Title
MISP improper authorization allows organization administrators to modify site administrator user settings
Summary
An improper authorization vulnerability in MISP allowed an authenticated organization administrator to access or modify user settings belonging to site administrator accounts within the same organization. The affected access-control checks scoped administrative actions by organization membership but did not exclude higher-privileged site administrator users. As a result, an organization administrator could potentially view or alter site administrator user settings and related login profile information, crossing the intended privilege boundary between organization administration and site-wide administration.
The patch hardens the ACL logic by excluding site administrator accounts from organization administrator–managed user sets, adding explicit authorization failure when a target user is not administrable, and ensuring user setting and login profile operations fail closed.

Title
MISP CRUDComponent delete validation bypass via operator precedence error
Summary
A logic error in the MISP CRUD component delete handler allowed validation failures to be bypassed when requests used the HTTP DELETE method. Due to missing parentheses in the delete condition, the expression was evaluated as ($validationError === null && POST) || DELETE, meaning a DELETE request could proceed even when the delete validation callback had rejected the operation. An authenticated attacker with access to an affected delete endpoint could abuse this flaw to delete records that should have been protected by application-level validation or authorization checks.

Title
ISE information disclosure
Summary
A vulnerability in the web-based management interface of Cisco ISE could allow an authenticated, remote attacker to obtain sensitive information from network users that are outside the security group that the attacker is assigned to.
This vulnerability exists because certain files lack proper authorization enforcement. An attacker with administrative privileges and management rights over network users could exploit this vulnerability by exporting the users. A successful exploit could allow the attacker to view passwords that are normally not visible to administrators.

Title
MISP object edit authorization bypass allows unauthorized sharing group assignment
Summary
An authorization flaw in MISP’s object add/edit handling allowed an authenticated user with object editing permissions to assign a MISP object, or attributes contained within an object, to a sharing group that the user was not authorized to use or view. When editing objects, the sharing group validation was performed against the wrong request data structure after object fields had been merged to the top level, causing the check to be bypassed. In addition, attributes embedded in objects were not individually validated for authorized sharing group use.
An attacker could craft a request with distribution set to 4 and an arbitrary sharing_group_id, potentially disclosing the existence or name of otherwise non-visible sharing groups and improperly modifying the distribution metadata of objects or contained attributes.

Title
MISP Dashboard Template ACL Bypass Due to VARCHAR-to-Integer Type Coercion in Permission Flag Comparison
Summary
Affected versions of MISP incorrectly filter dashboard templates that are restricted to a specific permission flag.
DashboardsController::listTemplates() allowed a template when either:
- its restrict_to_permission_flag matched one of the current user’s permission flags, or
- restrict_to_permission_flag equaled integer 0
However, restrict_to_permission_flag is a varchar. MySQL therefore performed numeric coercion when comparing the column against integer 0. Strings such as perm_site_admin convert numerically to zero, making expressions such as perm_site_admin = 0 evaluate true and causing the “unrestricted” branch to match permission-restricted templates as well.
Version affected: ≤2.5.45

fix: [acl] Compare the dashboard template permission flag as | ac03cd1103d5… |
Fix summary
The fix corrects the type mismatch in the permission flag comparison by replacing the integer literal 0 with the explicit string values '' and '0', which are the actual database values representing an unrestricted dashboard template. This ensures MySQL performs a proper string-to-string comparison, so only rows genuinely marked as unrestricted are returned, restoring the intended per-permission-level access control on dashboard templates.
Patch summary
In app/Controller/DashboardsController.php, the listTemplates() method's query condition was changed from ['Dashboard.restrict_to_permission_flag' => 0] to ['Dashboard.restrict_to_permission_flag' => ['', '0']]. A multi-line comment was added explaining that restrict_to_permission_flag is a VARCHAR column and that comparing it to integer 0 causes MySQL to coerce the column, making the clause a no-op. The two values that actually represent unrestricted access are the empty string (column default) and the string '0' (posted by the save form).
CVSS rationale
The vulnerability is exploitable over the network (AV:N) via the MISP web interface with low attack complexity (AC:L) and no attack target manipulation (AT:N). It requires a low-privilege authenticated user (PR:L) and no user interaction (UI:N). The impact is limited to confidentiality (VC:L) as restricted dashboard template definitions are disclosed to unauthorized users; there is no integrity or availability impact (VI:N, VA:N) and no secondary effects (SC:N, SI:N, SA:N). The severity is moderate because the disclosed data is dashboard template metadata rather than raw threat intelligence, but it still represents a breach of the intended access control boundary.
Weakness rationale
- CWE-863 The permission-based filter on dashboard templates was effectively bypassed because the type-coerced comparison matched all rows, allowing any authenticated user to access templates restricted to higher-privilege roles. The authorization check was present in code but did not function correctly.
- CWE-697 The root cause is a comparison between a VARCHAR column and an integer literal. MySQL's implicit type coercion caused the comparison to evaluate to TRUE for all non-numeric string values, making the intended filter a no-op. This is a classic incorrect comparison due to type mismatch.
Assumptions to verify
- The affected version range is inferred from the tag_version_boundary (v2.5.46 with 200 commits after fix); no explicit affected or fixed version is stated in the patch metadata.
- The vulnerability requires an authenticated MISP user with any role; the exact minimum privilege level needed to access the listTemplates endpoint is not specified in the patch.
- The impact is assessed as Low confidentiality because the disclosed data is dashboard template definitions (layout, widget configuration) rather than raw threat intelligence or user credentials.
- The MySQL type-coercion behavior described in the commit message and code comments is assumed to be accurate for the MySQL versions supported by MISP.

Title
MISP template builder exposes non-visible custom galaxies across organisations
Summary
An incorrect visibility condition in the MISP event template builder allowed authenticated non-site-admin users to view galaxies that should not have been visible to their organisation. The custom access-control condition intended to restrict galaxies to those owned by the user’s organisation or distributed beyond it used a PHP comparison expression instead of a query condition. As a result, enabled galaxies, including organisation-only custom galaxies belonging to other organisations, could be exposed in the template builder galaxy list. This could disclose metadata about private galaxy definitions to unauthorised users.

Title
MISP organization administrators can target site administrator accounts for password reset
Summary
An incorrect authorization vulnerability in MISP allows an organization administrator to target site administrator accounts belonging to the same organization through the administrative email functionality. The affected code restricted organization administrators to users within their own organization, but did not exclude accounts assigned a site administrator role from recipient queries. As a result, an organization administrator could perform privileged account-management actions, such as initiating a password reset workflow, against a higher-privileged site administrator account in the same organization.
Successful exploitation may allow an authenticated organization administrator to interfere with or potentially take over a site administrator account, resulting in privilege escalation and full compromise of the MISP instance’s confidentiality, integrity, and availability.
Attack prerequisites:
The attacker must be authenticated as an organization administrator in the same organization as a site administrator account.

Title
MISP: Improper sharing group authorization check when adding attributes
Summary
An improper authorization check in MISP’s attribute creation endpoint allowed an authenticated user with permission to add attributes to submit a sharing_group_id without triggering the corresponding sharing group authorization check, as long as the attribute distribution value was not explicitly set to 4 — “sharing group”.
As a result, a user could reference or associate an attribute with a sharing group they were not authorized to use. This could lead to an access-control bypass affecting the integrity of attribute sharing metadata and potentially expose or misuse restricted sharing group relationships.
The patch changes the authorization logic so that the sharing group permission check is performed whenever a non-empty sharing_group_id is provided, regardless of the selected distribution value.

Title
PackageKit: dnf5 backend ignores SIMULATE on RepoRemove
Summary
A flaw was found in PackageKit. PackageKit skips the polkit authorization check for transactions carrying the SIMULATE (dry-run) flag. In the dnf5 backend, the RepoRemove handler ignores that contract and always executes the real transaction because its guard is written as (role == REPO_REMOVE || !SIMULATE), which is always true for RepoRemove. An unprivileged local user can therefore perform a genuine package uninstall while claiming to simulate. This vulnerability only affects systems using PackageKit with the dnf5 backend.

Mitigation
Architecture and Design
- Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) [REF-229] to enforce the roles at the appropriate boundaries.
- Note that this approach may not protect against horizontal authorization, i.e., it will not protect a user from attacking others with the same role.
Mitigation
Architecture and Design
Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records. For example, a database may restrict access for medical records to a specific database user, but each record might only be intended to be accessible to the patient and the patient's doctor [REF-7].
Mitigation MIT-4.4
Architecture and Design
Strategy: Libraries or Frameworks
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
- For example, consider using authorization frameworks such as the JAAS Authorization Framework [REF-233] and the OWASP ESAPI Access Control feature [REF-45].
Mitigation
Architecture and Design
- For web applications, make sure that the access control mechanism is enforced correctly at the server side on every page. Users should not be able to access any unauthorized functionality or information by simply requesting direct access to that page.
- One way to do this is to ensure that all pages containing sensitive information are not cached, and that all such pages restrict access to requests that are accompanied by an active and authenticated session token associated with a user who has the required permissions to access that page.
Mitigation
System Configuration
Installation
Use the access control capabilities of your operating system and server environment and define your access control lists accordingly. Use a "default deny" policy when defining these ACLs.
