Sandboxie is a sandbox-based isolation software for 32-bit and 64-bit Windows NT-based operating systems. In versions 1.16.1 and below, a critical security vulnerability exists in password handling mechanisms. During encrypted sandbox creation, user passwords are transmitted via shared memory, exposing them to potential interception. The vulnerability is particularly severe during password modification operations, where both old and new passwords are passed as plaintext command-line arguments to the Imbox process without any encryption or obfuscation. This implementation flaw allows any process within the user session, including unprivileged processes, to retrieve these sensitive credentials by reading the command-line arguments, thereby bypassing standard privilege requirements and creating a significant security risk. This is fixed in version 1.16.2.

Sandboxie is a sandbox-based isolation software for 32-bit and 64-bit Windows NT-based operating systems. Starting in version 1.3.0 and prior to version 1.15.12, Api_SetSecureParam fails to sanitize incoming pointers, and implicitly trusts that the pointer the user has passed in is safe to read from. SetRegValue then reads an arbitrary address, which can be a kernel pointer, into a HKLM Security SBIE registry value. This can later be retrieved by API_GET_SECURE_PARAM. Version 1.15.12 fixes the issue.

Sandboxie is a sandbox-based isolation software for 32-bit and 64-bit Windows NT-based operating systems. Starting in version 1.3.0 and prior to version 1.15.12, Api_GetSecureParam fails to sanitize incoming pointers, and implicitly trusts that the pointer the user has passed in is safe to write to. GetRegValue then writes the contents of the SBIE registry entry selected to this address. An attacker can pass in a kernel pointer and the driver dumps the registry key contents we requested to it. This can be triggered by anyone on the system, including low integrity windows processes. Version 1.15.12 fixes the issue.

Sandboxie is a sandbox-based isolation software for 32-bit and 64-bit Windows NT-based operating systems. Starting in version 1.3.0 and prior to 1.15.12, API_GET_SECURE_PARAM has an arithmetic overflow leading to a small memory allocation and then a extremely large copy into the small allocation. Version 1.15.12 fixes the issue.

Sandboxie is a sandbox-based isolation software for 32-bit and 64-bit Windows NT-based operating systems. Starting in version 0.0.1 and prior to 1.15.12, API_SET_SECURE_PARAM may have an arithmetic overflow deep in the memory allocation subsystem that would lead to a smaller allocation than requested, and a buffer overflow. Version 1.15.12 fixes the issue.

Sandboxie is a sandbox-based isolation software for 32-bit and 64-bit Windows NT-based operating systems. An authenticated user (**UserA**) with no privileges is authorized to read all files created in sandbox belonging to other users in the sandbox folders `C:\Sandbox\UserB\xxx`. An authenticated attacker who can use `explorer.exe` or `cmd.exe` outside any sandbox can read other users' files in `C:\Sandbox\xxx`. By default in Windows 7+, the `C:\Users\UserA` folder is not readable by **UserB**. All files edited or created during the sandbox processing are affected by the vulnerability. All files in C:\Users are safe. If `UserB` runs a cmd in a sandbox, he will be able to access `C:\Sandox\UserA`. In addition, if **UserB** create a folder `C:\Sandbox\UserA` with malicious ACLs, when **UserA** will user the sandbox, Sandboxie doesn't reset ACLs ! This issue has not yet been fixed. Users are advised to limit access to their systems using Sandboxie.
