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 29 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.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), 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

Upgrade ZwickRoell GmbH & Co. KG Test Data Management to 3.0.8.

ZwickRoell GmbH & Co. KGTest Data Management	Affected <3.0.8	Fixed in 3.0.8

AI-suggested

Upgrade to ZwickRoell Test Data Management version 3.0.8 or later, where this vulnerability is fixed.
If immediate patching is not possible, implement network-level access controls to restrict access to the /server/node_upgrade_srv.js endpoint, limiting it to trusted internal IP addresses only.
Employ web application firewalls (WAFs) with custom rules to detect and block directory traversal patterns in the firmware parameter.
Conduct regular audits of server file permissions to ensure sensitive files are not accessible by the application user beyond what is necessary.
Monitor logs for suspicious requests containing directory traversal sequences targeting the vulnerable endpoint.
Implement strict input validation and sanitization on all parameters, especially those related to file paths, to prevent traversal attacks.
Isolate the Test Data Management server in a segmented network zone to reduce exposure.
Educate security teams about this vulnerability to enable rapid detection and response to potential exploitation attempts.

Description

CVE-2026-29522 is a high-severity local file inclusion (LFI) vulnerability affecting ZwickRoell GmbH & Co. KG Test Data Management software versions prior to 3.0.8. The vulnerability exists in the /server/node_upgrade_srv.js endpoint, where an unauthenticated attacker can exploit improper pathname limitation (CWE-22) by supplying directory traversal sequences via the firmware parameter. This allows attackers to access arbitrary files on the server, leading to sensitive information disclosure. The vulnerability requires no authentication or user interaction and can be exploited remotely over the network. Although no known exploits are currently reported in the wild, the CVSS 4.0 base score of 8.

Impact

The primary impact of CVE-2026-29522 is unauthorized disclosure of sensitive information due to local file inclusion via directory traversal. Attackers can access configuration files, credentials, logs, or other sensitive data stored on the server, potentially enabling further attacks such as privilege escalation or lateral movement. This compromises the confidentiality of the affected systems and may lead to intellectual property theft, exposure of personally identifiable information (PII), or disruption of business operations if sensitive operational data is leaked. Since the vulnerability requires no authentication and can be exploited remotely, it poses a significant risk to organizations using the affected software globally. The lack of known exploits in the wild currently reduces immediate risk, but the high CVSS score and ease of exploitation make it a critical issue that could be targeted by threat actors once exploit code becomes available. Industries relying on ZwickRoell Test Data Management for quality assurance and testing, especially in manufacturing, automotive, and materials testing sectors, are particularly at risk.

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).
