Vulnerabilities in the My Account and User Management components in CIPPlanner CIPAce before 9.17 allows attackers to escalate their access levels. A low-privileged authenticated user can gain access to other people's accounts by tampering with the client's user id to change their account information. A low-privileged authenticated user can elevate his or her system privileges by modifying the information of a user role that is disabled in the client.
Vulnerabilities in the File Download and Get File handler components in CIPPlanner CIPAce before 9.17 allow attackers to download unauthorized files. An authenticated user can easily change the file id parameter or pass the physical file path in the URL query string to retrieve the files. (Retrieval is not intended without correct data access configured for documents.)
Unrestricted Upload of File with Dangerous Type vulnerabilities exist in the rich text editor and document manage components in CIPPlanner CIPAce before 9.17. An authorized user can upload executable files when inserting images in the rich text editor, and upload executable files when uploading files on the document management page. Those executables can be executed if they are not stored in a shared directory or if the storage directory has executed permissions.
A Use of Single-factor Authentication vulnerability in the Authentication component of CIPPlanner CIPAce before 9.17 allows attackers to bypass a protection mechanism. When the system is configured to allow login with internal accounts, an attacker can possibly obtain full authentication if the secret in a single-factor authentication scheme gets compromised.
