CVE intelligence and bounded remediation
CVE-2022-23104 — Win-911 Win-911 2021 R1 security vulnerability
High
CVSS 7.8
WIN-911 2021 R1 and R2 are vulnerable to a permissions misconfiguration that may allow an attacker to locally write files to the program Operator Workspace directory, which holds DLL files and executables. A low-privilege attacker could write a malicious DLL file to the Operator Workspace directory to achieve privilege escalation and the permissions of the user running the program.

Matched remediation archetype
Privilege escalation and unsafe privilege management
This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.
Check exposure
- Map service accounts, operating-system identities, roles, capabilities, impersonation, set-user transitions, and administrative helper paths.
- Determine whether untrusted users or lower-privilege processes can reach the affected transition or modify inputs it trusts.
- Review file, socket, registry, device, job, container, and cloud-role permissions used before and after privilege changes.
Remediate safely
- Apply the supported fix and redesign privileged operations as a minimal, authenticated, allowlisted interface.
- Drop privileges before processing untrusted input, verify the drop succeeds, and remove unnecessary roles, capabilities, and write permissions.
- Validate ownership and permissions at time of use and add explicit lower-to-higher privilege boundary tests.
