iStoreOS: Remote code execution via task_id in tasks-lib.lua
Summary
iStoreOS firmware up to version 24.10.7 contains a flaw in tasks-lib.lua that allows a remote attacker to execute arbitrary code on the device via the task_id parameter. The CVE record classifies the issue as CWE-94 (code injection) with a CVSS 3.1 score of 9.8. The NVD text does not state whether authentication is required, and no vendor advisory or confirmed fix was found, so the exact preconditions remain unverified.
Affected
- iStoreOS istoreos-24.10.7 and earlier (CVE record)
- Third-party list (VulDB): 24.10.0 through 24.10.7
- Versions before 24.10.0, such as 22.03: unknown
Fixed in
- Vendor fix: Unknown.
- VulDB recommends upgrading to 24.10.8 or later; this is not a vendor statement and has not been verified.
Workaround
- No vendor-confirmed workaround found.
- Do not expose the web interface or management services to the internet.
- Limit access to trusted LAN addresses and review who can reach the web UI.
- Monitor for unexpected processes or outbound connections.
Exploitation
- CISA SSVC: exploitation status PoC, automatable yes, technical impact total.
- VulDB: no exploit available at last update.
- EPSS about 0.6 to 0.8 percent; KEV status listed as No by a third-party site (not checked directly).
- Referenced pastebin and PRISMI-Team write-up not reviewed; content unverified.
Our recommendation
- Identify all iStoreOS devices, including their versions and whether they are internet-facing.
- Upgrade to the newest available release from the vendor and confirm the fix once the vendor publishes it.
- Until a fix is confirmed, remove internet exposure of admin interfaces and restrict access to trusted addresses.
- Monitor logs and network traffic for unexpected processes or connections.
- Treat devices that serve as gateways for business networks as high priority.
