Patch only the product branches with a verified fix
Fix availability varies by productMedium technical severity with no CISA KEV confirmation; remediate through the normal risk-based patch cycle unless local exposure raises the priority. Verified remediation exists for at least one product or source, but 3 structured product or package states remain unresolved. Apply remediation only to the exact product branch confirmed by its source.

Compensating controls
- Apply the linked authoritative mitigation while planning the permanent fix.
- 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 Telit Cinterion BGS5 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.
Remediation availability differs by product scope
Verified remediation exists for at least one product or source, but 3 structured product or package states remain unresolved. Apply remediation only to the exact product branch confirmed by its source.

The vendor explicitly identifies these products as affected by this CVE.
- Arctic Wireless Gateway ARG600 with Telit PLS62-W wireless modem module.
- Arctic Wireless Gateway ARC600 with Telit PLS62-W wireless modem module.
- Arctic Wireless Gateway ARR600 with Telit PLS62-W wireless modem module.
- Summary
- Files or Directories Accessible to External Parties vulnerability that could allow an attacker with physical access to the target system to obtain a read/write access to any files and directories on the wireless modem module, including hidden files and directories.
- Remediation
- The following mitigations can be considered • Obtain a private cellular access point to limit impact of any potential exploit. Contact your cellular provider for availability. • Mitigate the cellular module vulnerabilities by contacting the mobile network operator and requesting to disable binary SMS for your mobile subscription. o Note that binary SMS service is often disabled by default based on operator restrictions. o If SMS services are not used in the solution, consider disabling them completely. • Establish remote connections through OpenVPN. If the SSH protocol is used for remote administration of Arctic wireless gateway, it is to be considered logging in to the wireless gateway through an OpenVPN tunnel. • Do not expose SSH port to public networks. Keep the SSH port closed to public networks and thus limit the number of potential attackers who can attempt to exploit the vulnerability. This way only devices within your private network or those connected through a secure VPN can access the SSH server. • Restrict physical access to the product. Refer to section General security recommendations for further advice on how to keep your system secure.

Fix availability varies by product01
What, why and how
A CWE-552: Files or Directories Accessible to External Parties vulnerability exists in Telit Cinterion BGS5, Telit Cinterion EHS5/6/8, Telit Cinterion PDS5/6/8, Telit Cinterion ELS61/81, Telit Cinterion PLS62 that could allow an attacker with physical access to the target system to obtain a read/write access to any files and directories on the targeted system, including hidden files and directories.
What
A CWE-552: Files or Directories Accessible to External Parties vulnerability exists in Telit Cinterion BGS5, Telit Cinterion EHS5/6/8, Telit Cinterion PDS5/6/8, Telit Cinterion ELS61/81, Telit Cinterion PLS62 that could allow an attacker with physical access to the target system to obtain a read/write access to any files and directories on the targeted system, including hidden files and directories.
Why
A file or directory that should be restricted can be reached by an external party because its access controls or placement are unsafe.
How
An attacker operating through physical access may attempt exploitation without authentication or user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

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
- physical access → Files or Directories Accessible to External Parties → cause the confidentiality, integrity or availability impact described by the vendor
- Attack surface

- Privileges required
- None: unauthenticated exploitation is possible
- User interaction

- 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-552 ↗
CWE-552: Files or Directories Accessible to External Parties. The product makes files or directories accessible to unauthorized actors, even though they should not be.

- No specific living-off-the-land technique is confirmed in the structured sources. Monitor normal administration tools for activity inconsistent with the affected service's baseline.

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 availability varies by product
- Affected
- Action
- Use the product-specific evidence above. Patch only products with a verified fixed release, and keep every affected or under-investigation state without a matching fix in the remediation queue.
- Workaround
- The following mitigations can be considered • Obtain a private cellular access point to limit impact of any potential exploit. Contact your cellular provider for availability. • Mitigate the cellular module vulnerabilities by contacting the mobile network operator and requesting to disable binary SMS for your mobile subscription. o Note that binary SMS service is often disabled by default based on operator restrictions. o If SMS services are not used in the solution, consider disabling them completely. • Establish remote connections through OpenVPN. If the SSH protocol is used for remote administration of Arctic wireless gateway, it is to be considered logging in to the wireless gateway through an OpenVPN tunnel. • Do not expose SSH port to public networks. Keep the SSH port closed to public networks and thus limit the number of potential attackers who can attempt to exploit the vulnerability. This way only devices within your private network or those connected through a secure VPN can access the SSH server. • Restrict physical access to the product.
