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

Attack Vector: Adjacent: The vulnerable system is bound to a protocol stack, but the attack is limited at the protocol level to a logically adjacent topology. This can mean an attack must be launched from the same shared proximity (e.g., Bluetooth, NFC, or IEEE 802.11) or logical network (e.g., local IP subnet), or from within a secure or otherwise limited administrative domain (e.g., MPLS, secure VPN within an administrative network zone).
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.

Exploitation evidence

Disclosed: evidence found.
CVE published 2 Oct 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

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 2026-10-25.

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

1. Immediately restrict file system permissions for the ChangeFlow application to limit accessible directories strictly to necessary paths. 2. Implement network segmentation and firewall rules to restrict access to ChangeFlow servers to trusted hosts and networks only, minimizing exposure to adjacent network attackers. 3. Monitor logs and network traffic for unusual file access patterns or unexpected downloads from ChangeFlow instances. 4. Employ application-layer controls such as web application firewalls (WAFs) with custom rules to detect and block path traversal attempts targeting ChangeFlow. 5. If possible, disable or restrict features that allow downloading of code or external resources until a vendor patch is available. 6. Engage with GTONE support to obtain patches or official remediation guidance as soon as they are released. 7. Conduct internal audits to identify all ChangeFlow deployments and prioritize remediation based on criticality and exposure. 8. Educate IT and security teams about this vulnerability to ensure rapid detection and response to potential exploitation attempts.

Description

Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal'), Download of Code Without Integrity Check vulnerability in GTONE ChangeFlow allows Path Traversal.This issue affects ChangeFlow: All versions to v9.0.1.1.

Impact

For European organizations, exploitation of CVE-2025-11182 could lead to unauthorized access to sensitive internal files and the potential introduction of malicious code into critical workflows. This threatens confidentiality and could disrupt business processes if attackers manipulate or exfiltrate data. Industries such as finance, manufacturing, and government agencies using GTONE ChangeFlow are particularly vulnerable, as they often handle regulated or sensitive information. The path traversal flaw could be exploited by attackers within the same network segment, including insider threats or lateral movement by external attackers who have breached perimeter defenses. The lack of integrity checks on downloaded code further increases the risk of supply chain or internal compromise. Given the interconnected nature of European IT environments and regulatory requirements like GDPR, a breach could result in significant legal and financial consequences. Organizations may face operational downtime, reputational damage, and regulatory penalties if this vulnerability is exploited.

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).
