CVE-2025-62520 is a medium-severity Improper Authorization (CWE-285) vulnerability in Mantisbt Mantisbt. Its CVSS base score is 5.3 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Local Groups (T1069.001); ranked at the 15th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and AC-4 (Information Flow Enforcement) — see the control section below for these in your framework.

Mantis Bug Tracker (MantisBT) is an open source issue tracker. In versions 2.27.1 and below, due to insufficient access-level checks, any non-admin user with access to manage_config_columns_page.php can use the Copy From action to retrieve the columns configuration from a…

Why these techniques?
The vulnerability allows non-admin users to access configuration data (column settings) from private projects they should not have access to via insufficient authorization checks on manage_config_columns_page.php. This directly maps to Local Permission Groups Discovery (T1069.001) and Local Account Discovery (T1087.001) as the attacker can enumerate or access project-specific configuration information beyond their authorized scope.

Mitigating Controls (NIST 800-53 r5) AI
Directly enforces access-level checks on manage_config_columns_page.php to block unauthorized Copy From actions on private project data.
Ensures non-admin users receive only the minimum privileges needed, preventing access to private project column configurations.
Enforces information flow rules between projects so column configuration data cannot cross private-project boundaries.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
PR.AA-05 mostly prevents CWE-285 via enforced policy, reviews, and least-privilege authorization decisions, yet CWE-285 remains only partially prevented because code-level check omissions or errors can still occur outside that single control.
Secure SDLC practices catch and eliminate most authorization defects before release, yet a single broad outcome cannot address every design, role, and runtime facet of CWE-285.
PR.AA-01 supplies managed identities and access-request workflows that can support downstream authorization decisions, yet does nothing to enforce or verify authorization checks inside a product, leaving CWE-285 fully unaddressed by this control alone.
Network segmentation/zero-trust limits external reachability (partial prevention of exploitation) but leaves application-level authorization logic untouched, so the CWE remains fully introducible and only one facet of its risk is addressed.
PR.PS-05 blocks unauthorized binaries/DNS while CWE-285 is an in-product authorization-check defect, so the control neither prevents the weakness nor removes any of its risk.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Granular, policy-driven assignment of permissions and dynamic enforcement of those permissions prevent the incorrect or missing authorization decisions that lead to improper authorization flaws.
By requiring documented authorization rules and periodic policy reviews, the control makes it less likely that authorization decisions will be omitted or implemented inconsistently across applications.
Mapping access rights to information classification and business requirements forces correct enforcement of authorization decisions, blocking the incorrect authorization weakness at the policy and implementation stage.
Independent reviewers evaluate whether authorization logic matches policy, thereby reducing the window in which incorrect or missing authorization checks remain in production.
By requiring managers to verify that authorization decisions match policy and to remediate deviations, the control limits the persistence of incorrect or missing authorization checks.
Requiring authorization processes and privilege assignments to be specified during project initiation prevents downstream components from receiving overly broad or incorrect rights that would allow unauthorized actions.
