g5_digital_fault_recorder: Path Traversal: '../filedir'
CVE-2024-22079 is a high-severity path traversal: '../filedir' vulnerability in g5_digital_fault_recorder from Elspec-ltd, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 1.1.4.15 as the first without the flaw, so updating g5_digital_fault_recorder to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 1.02% chance of exploitation within 30 days, higher than 64% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update g5_digital_fault_recorder to 1.1.4.15 or a later version.
- Update G5dfr Firmware to 1.2.1.12 or a later version.
- Read the advisory on elspec-ltd.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
An issue was discovered in Elspec G5 digital fault recorder versions 1.1.4.15 and before. Directory traversal can occur via the system logs download mechanism.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Path Traversal: '../filedir'
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize../ sequences that can resolve to a location that is outside of that directory.
How developers prevent this class of flaw
- Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174). Such errors could be used to bypass allowlist validation schemes by introducing dangerous inputs after they have been checked.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: yes, technical impact: partial).
- Record last changed materially (score, affected products, status or references).
