Quest KACE Desktop Authority insecure named pipe permissions leading to SYSTEM/local admin RCE

IdentifiersCVE-2025-67813CWE-732

Quest KACE Desktop Authority (through 11.3.1) exposes a SYSTEM-run agent service IPC endpoint via the named pipe ScriptLogic_Server_NamedPipe_9300 (also accessible remotely over SMB). The pipe’s access controls are overly permissive, allowing any authenticated domain user to connect and invoke high-risk RPC-style operations implemented by the service (custom MFC CArchive-based protocol). Supported operations include AdminExec (arbitrary command execution with elevated/local admin context), DllInjection (inject an arbitrary DLL into a specified process, including loading from a UNC path), InvokeCOM (instantiate/invoke COM objects under an elevated token), ImpersonateAdmin (token impersonation), and Credentials (returning the Desktop Authority service account username/password in plaintext). This design/permission flaw enables network-based abuse of privileged functionality on hosts running the Desktop Authority agent.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

A remote authenticated domain user can achieve remote code execution on affected endpoints by invoking privileged operations over the named pipe (notably AdminExec), effectively executing commands with elevated privileges (described as local administrator / SYSTEM-context service actions). Additional impact includes potential credential disclosure (plaintext service account credentials), arbitrary DLL injection into processes, and privileged COM invocation/token impersonation, enabling full host compromise and follow-on lateral movement.

Mitigation

If you can’t patch tonight, do this now.

If patching is delayed: restrict/segment SMB access to endpoints running the Desktop Authority agent (block inbound TCP/445 from untrusted/user segments), isolate management infrastructure from general user networks, disable/uninstall the agent where not required, and monitor for unusual remote connections/usage of ScriptLogic_*_NamedPipe_9300 named pipes.

Remediation

Patch, then assume compromise.

Apply Quest’s fix/update that corrects the named pipe permissions/design (Quest KB: “Quest KACE Desktop Authority Insecure Named Pipe Permissions (CVE-2025-67813) (4381743)”). Practically, upgrade to a release newer than Desktop Authority 11.3.1 that includes the vendor-validated remediation.
