Compensating controls
- Restrict local access and enforce least privilege on affected hosts.
- Monitor vendor guidance and exploitation sources for a material change.
Verification
- Confirm that the asset runs Cisco Cisco Meraki Systems Manager Agent and falls inside the recorded affected range.
- Recheck the vendor advisory before scheduling a change because no verified fixed version is currently retained.
- Validate exposure, authentication requirements and compensating controls in the actual environment.
- Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.

What, why and how
A vulnerability in Cisco Meraki Systems Manager (SM) Agent for Windows could allow an authenticated, local attacker to execute arbitrary code with elevated privileges. This vulnerability is due to incorrect handling of directory search paths at runtime. A low-privileged attacker could exploit this vulnerability by placing both malicious configuration files and malicious DLL files on an affected system, which would read and execute the files when Cisco Meraki SM launches on startup. A successful exploit could allow the attacker to execute arbitrary code on the affected system with SYSTEM privileges.
What
A vulnerability in Cisco Meraki Systems Manager (SM) Agent for Windows could allow an authenticated, local attacker to execute arbitrary code with elevated privileges. This vulnerability is due to incorrect handling of directory search paths at runtime. A low-privileged attacker could exploit this vulnerability by placing both malicious configuration files and malicious DLL files on an affected system, which would read and execute the files when Cisco Meraki SM launches on startup. A successful exploit could allow the attacker to execute arbitrary code on the affected system with SYSTEM privileges.
Why
The product uses a fixed or controlled search path to find resources, but one or more locations in that path can be under the control of unintended actors.
How
An attacker operating through local access may attempt exploitation with low privileges. If successful, the issue may execute code or commands in the affected security context.

Exploit reality and attack path
CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
Observed exploitation No confirmed evidence
?
Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
Public PoC / exploit material None recorded
?
Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
- Likely attack path
- local access → Uncontrolled Search Path Element → execute code or commands in the affected security context
- Attack surface
- Local
- Privileges required
- Low: a basic authenticated account is required
- User interaction
- Required interaction required
- Attack complexity
- Low: no specialised conditions are recorded
- Security boundary
- Unchanged: impact remains within the vulnerable component's security authority
- Weakness
?
CWE means Common Weakness Enumeration: a standard category for the underlying weakness. - CWE-427 ↗
CWE-427: Uncontrolled Search Path Element. The product uses a fixed or controlled search path to find resources, but one or more locations in that path can be under the control of unintended actors.
- CVSS vector
?
CVSS means Common Vulnerability Scoring System. The vector records the metric values used to calculate technical severity. CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:HCommon Vulnerability Scoring System 3.1: the compact vector below is decoded into plain language.
AVLocalAttack vector: The attacker needs local access to the vulnerable system.ACLowAttack complexity: No specialised conditions are required beyond attacker-controlled input.PRLowPrivileges required: The attacker needs basic user-level privileges.UIRequiredUser interaction: Another user must perform an action for exploitation to succeed.SUnchangedScope: The security impact remains within the vulnerable component's authority.CHighConfidentiality impact: A successful attack can cause a major loss.IHighIntegrity impact: A successful attack can cause a major loss.AHighAvailability impact: A successful attack can cause a major loss.- Post-exploitation / living off the land
- After compromise, an attacker may use built-in shells, scripting engines, scheduled tasks and native network utilities for discovery, persistence or movement. This is a plausible LoTL path, not evidence that it has occurred for every attack.

Patch and workaround
Operational remediation based on structured source evidence.
- Status
?
Patch availability is based on structured fixed-version fields and authoritative update references. If no fix is verified, check the vendor advisory before making a change. - Fix not verified
- Affected
- Cisco Meraki Systems Manager Agent: 4.1.5, 4.1.4, 4.1.1, 4.0, 3.8.2, 3.7.2, 3.7.1, 3.7.0, 3.6.0, 3.5.2, 3.1.4, 3.1.3, 3.1.2, 3.1.1, 3.0.3, 3.0.2, 3.0.1, 3.0.0, 2.0.0, 1.0.99, 1.0.98
- Fixed
- No fixed version is explicitly recorded in the structured CVE data.
- Action
- No verified patch reference is present in the current structured sources. Check the vendor advisory before making a change.
- Workaround
