| 标题 | sanluan publiccms 5.0 Authorization Bypass Through User-Controlled SQL Primary Key |
|---|
| 描述 | PublicCMS has a missing authorization vulnerability in GET /admin/cmsContent/exportExcel and GET /admin/cmsContent/exportData. The authenticated account can export site content outside its intended user or department scope, including content owned by another administrator. The tested impact is read-only bulk disclosure within the site; no cross-site impact was established
Attack precondition: The attacker is an authenticated backend administrator who can cause a target SysUser record to contain an integer outside the valid content permission values. In the isolated local test, this was done through the authorized sysUser/save workflow while the account was marked as a superuser
Affected endpoint: GET /admin/cmsContent/exportExcel and GET /admin/cmsContent/exportData
Affected authorization property: SysUser.contentPermissions, CmsContentQuery.userId, and CmsContentQuery.deptId
Security impact: The authenticated account can export site content outside its intended user or department scope, including content owned by another administrator. The tested impact is read-only bulk disclosure within the site; no cross-site impact was established |
