Sandbox escape with SYSTEM-level code execution in Sandboxie-Plus before 1.17.6 allows a process confined inside a sandbox to run arbitrary code in an unsandboxed host process. The privileged GuiServer service trusts attacker-supplied thread and function-pointer values from a GUI window-hook registration request and dispatches them via QueueUserAPC while running as SYSTEM, defeating the core isolation guarantee of the product. No public exploit identified at time of analysis and the flaw is not listed in CISA KEV, but the mechanism is a full sandbox-to-host escape.
Stack-based buffer overflow in Sandboxie-Plus SbieSvc service enables sandboxed processes to escape isolation and execute code as SYSTEM. Affected versions 1.17.2 and earlier allow malicious sandboxed code to overflow a fixed 160-wide-character stack buffer in NamedPipeServer::OpenHandler via crafted named pipe open requests, bypassing the fundamental security boundary Sandboxie provides. Fixed in version 1.17.3. EPSS data unavailable, no CISA KEV listing or public exploit identified at time of analysis, but the security boundary violation represents a complete defeat of Sandboxie's core function.
Stack-based buffer overflow in Sandboxie-Plus ProcessServer handlers allows local authenticated attackers to execute arbitrary code as SYSTEM or crash the SbieSvc service. The vulnerability affects versions 1.17.2 and earlier, stems from unsafe wcscpy operations on unchecked WCHAR fields from service pipe requests, and has been patched in version 1.17.3. The service pipe's NULL DACL permits any local process to connect and trigger the flaw before authorization checks execute, enabling privilege escalation from low-privileged local accounts. No public exploit code identified at time of analysis, though the technical details in the GitHub advisory provide sufficient information for skilled attackers to develop exploits.
Local privilege escalation to SYSTEM in Sandboxie-Plus 1.17.2 and earlier allows low-privileged interactive users to trigger stack buffer overflow in SbieSvc service via unauthenticated IPC, bypassing sandbox isolation controls. The vulnerability exists in the RunSbieCtrl handler which processes crafted messages before security checks and copies unbounded input into a 128-character stack buffer. Fixed in version 1.17.3. EPSS data unavailable; not listed in CISA KEV at time of analysis, but publicly disclosed via GitHub Security Advisory with technical details sufficient for exploit development.
Stack buffer overflow in Sandboxie-Plus SbieSvc proxy service enables SYSTEM privilege escalation from sandboxed processes, including Security Hardened Sandboxes. Attackers chain an information disclosure (returning up to 32KB uninitialized stack memory with ASLR/stack cookie bypass) with an unbounded memcpy overflow in the GetRawInputDeviceInfoSlave IPC handler. Intel CET shadow stacks block ROP exploitation but not the information leak itself. Vendor-released patch available in version 1.17.3. No public exploit identified at time of analysis, but attack complexity is rated high (AC:H) with low privilege requirements (PR:L), making this viable for motivated attackers targeting sandbox environments.
INI injection in Sandboxie-Plus versions 1.17.2 and earlier enables any local low-privilege user to bypass EditAdminOnly and ConfigPassword protections, inject malicious directives into the global Sandboxie.ini file, create unrestricted sandbox sections, and escalate to SYSTEM privileges. The background service fails to authorize IPC messages for UserSettings_* sections and does not sanitize CRLF characters in MSGID_SBIE_INI_ADD_SETTING and MSGID_SBIE_INI_SET_SETTING parameters, allowing section header injection. Fixed in version 1.17.3 released by the vendor. No CISA KEV listing or public exploit identified at time of analysis, but technical details in GitHub advisory provide sufficient information for exploit development.
Local denial of service in Sandboxie 1.17.2 and earlier allows unprivileged processes inside Standard Sandbox configurations to crash the Windows kernel (BSOD) by sending malformed IOCTL requests to the SandboxieDriverApi kernel driver. Fixed in version 1.17.3 released by Sandboxie-Plus. Security Hardened Sandbox configurations are not affected. No active exploitation confirmed (not in CISA KEV), but the vulnerability is trivially exploitable by any process within an affected sandbox, enabling local attackers or malicious sandboxed applications to force immediate system-wide service disruption.
Sandboxie-Plus versions 1.17.2 and earlier are vulnerable to privilege escalation via a Time-of-Check-to-Time-of-Use (TOCTOU) race condition during addon installation. When a user initiates addon installation through the SandMan interface, the UpdUtil.exe process runs as SYSTEM and stages files in the user-writable %TEMP%\sandboxie-updater directory. An unprivileged local attacker can exploit the window between hash verification and file extraction to replace the addon cabinet file with a malicious executable, resulting in arbitrary code execution as SYSTEM without UAC prompts. Patch version 1.17.3 addresses this flaw; no active exploitation has been publicly confirmed, though the attack is trivially reproducible given local access and user interaction.
Sandboxie-Plus versions 1.17.2 and earlier contain a cryptographic implementation flaw in SbieIniServer::HashPassword that reduces SHA-1 password hash entropy from 160 bits to 80 bits by incorrectly shifting the high nibble of each byte right by 8 instead of 4, combined with an unsalted hashing scheme. This makes leaked or backed-up EditPassword hashes significantly easier to brute-force, enabling attackers with local access and low privileges to recover plaintext passwords through offline attack. The vulnerability is fixed in version 1.17.3.
Sandboxie 5.30 contains a denial of service vulnerability that allows local attackers to crash the application by supplying an excessively long string in the Program Alerts configuration field. Rated medium severity (CVSS 6.2), this vulnerability is no authentication required, low attack complexity. Public exploit code available and no vendor patch available.
