Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

AI-suggested

Until an official patch is released, organizations should implement network-level controls to restrict access to Elspec G5 digital fault recorders. This includes isolating these devices within secure network segments, applying strict firewall rules to limit access to trusted management hosts, and disabling or restricting the logs download feature if possible. Monitoring network traffic for unusual access patterns to the logs download endpoint can help detect exploitation attempts. Employing intrusion detection or prevention systems with custom signatures targeting directory traversal attempts against these devices is advisable. Additionally, organizations should conduct thorough audits of device configurations and logs to identify any unauthorized access. Coordination with Elspec for timely patch deployment is critical once updates become available. Finally, incorporating these devices into a broader industrial control system security framework with regular vulnerability assessments will reduce exposure.

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.

Impact

The primary impact of CVE-2024-22079 is unauthorized disclosure of sensitive information stored on Elspec G5 digital fault recorders. Attackers exploiting this vulnerability can access system files that may contain configuration details, user credentials, or operational logs. Such information disclosure can facilitate further attacks, including lateral movement within industrial control systems or disruption of power grid operations. Although the vulnerability does not allow modification or disruption of device functionality, the exposure of sensitive data can undermine the security posture of critical infrastructure operators. Organizations relying on these devices for fault recording and analysis in electrical grids face risks of espionage, data leakage, and potential preparation for more damaging attacks. The lack of authentication and user interaction requirements increases the risk of automated scanning and exploitation attempts, especially in environments where these devices are accessible from less trusted networks.

CWE-24Path Traversal: '../filedir' (opens in a new tab)
Variant weakness
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.
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
Implementation · Input Validation
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).
