DescriptionCVE.org

Snipe-IT is an IT asset/license management system. Prior to 8.6.3, a restricted user can request /api/v1/users/{target_id}/eulas to obtain another user's randomized EULA filename and then download the signed file through /account/stored-eula-file/{filename}. The primary /stored-eula-file/{filename} route correctly denies access, but app/Http/Controllers/ProfileController.php and app/Http/Controllers/Api/UsersController.php do not consistently enforce ownership and target-user authorization. This issue is fixed in version 8.6.3.

AnalysisAI

Insecure direct object reference in Snipe-IT prior to 8.6.3 allows any authenticated low-privilege user to read signed EULA documents belonging to other users by exploiting inconsistent authorization enforcement across two Laravel controllers. The attacker calls /api/v1/users/{target_id}/eulas to learn the target's randomized EULA filename, then retrieves the file via the /account/stored-eula-file/{filename} route, which bypasses the stricter checks enforced by the primary /stored-eula-file/{filename} endpoint. …

Vulnerability AssessmentAI

Exploitation The attacker must hold a valid Snipe-IT account with at least restricted-user access - unauthenticated exploitation is not possible. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 score of 7.1 (AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N) accurately reflects the realistic threat profile: the attack is remotely exploitable with no special conditions, requires only a valid low-privilege account, and yields high confidentiality impact on the vulnerable system. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An authenticated restricted user - such as a helpdesk technician with standard Snipe-IT access - sends a GET request to /api/v1/users/42/eulas where 42 is a manager's user ID, obtaining the randomized filename of the manager's signed EULA document. The attacker then fetches /account/stored-eula-file/{filename} and downloads the PDF, bypassing the ownership check that the primary route would have enforced. …
Remediation The primary fix is to upgrade Snipe-IT to version 8.6.3, which tightens authorization to object-level checks in both app/Http/Controllers/Api/UsersController.php and app/Http/Controllers/ProfileController.php. … Detailed patch versions, workarounds, and compensating controls in full report.
