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

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, 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: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: High: There is a total loss of confidentiality, resulting in all information within the Vulnerable System being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact. For example, an attacker steals the administrator's password, or private encryption keys of a web server.
Vulnerable system integrity: None: There is no loss of integrity within the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.

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 2026-10-26.

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 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.

AI-suggested

Immediate mitigation should focus on network-level controls: restrict access to Digitek ADT1100 and DT950 devices to trusted internal networks and management stations only, using firewalls and network segmentation. Implement strict ingress filtering to prevent unauthorized external access. Monitor device logs and network traffic for suspicious requests containing directory traversal patterns or unusual file access attempts. Until official patches are released, consider deploying web application firewalls (WAFs) or intrusion prevention systems (IPS) with custom rules to detect and block URL-encoded traversal sequences targeting these devices. Review and harden device configurations to minimize exposed services and disable unnecessary features. Engage with PRIMION DIGITEK for patch availability and apply updates promptly once released. Conduct security awareness training for administrators managing these devices to recognize exploitation indicators. Finally, perform regular vulnerability assessments and penetration tests focusing on these devices to identify and remediate exposure.

Description

Path Traversal vulnerability in Digitek ADT1100 and Digitek DT950 from PRIMION DIGITEK, S.L.U (Azkoyen Group). This vulnerability allows an attacker to access arbitrary files in the server's file system, thet is, 'http://<host>/..%2F..% 2F..%2F..%2F..%2F..%2F..%2F..%2F..%2Fetc%2Fpasswd'. By manipulating the input to include URL encoded directory traversal sequences (e.g., %2F representing /), an attacker can bypass the input validation mechanisms ans retrieve sensitive files outside the intended directory, which could lead to information disclosure or further system compromise.

Impact

For European organizations, this vulnerability poses a significant risk of unauthorized disclosure of sensitive files, including configuration files, credentials, or other critical data stored on the affected devices. Such exposure could facilitate further attacks, including privilege escalation or lateral movement within networks. Organizations in sectors such as government, critical infrastructure, manufacturing, and building security that deploy PRIMION DIGITEK devices for access control or security monitoring are particularly vulnerable. The compromise of these devices could undermine physical security controls and lead to broader operational disruptions. Additionally, the ability to remotely exploit this vulnerability without authentication increases the attack surface, especially if devices are accessible from less secure network segments or the internet. The potential impact extends beyond confidentiality to operational integrity if attackers leverage disclosed information to disrupt or manipulate device functions.

CWE-22Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') (opens in a new tab)
Base weaknessLikelihood of exploit: HighCWE Top 25 (2025): #6OWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted 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.
Architecture and Design
For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks…
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).
