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: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

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 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.

2) Network segmentation: Restrict access to the QConvergeConsole management interface to trusted internal networks and limit exposure to the internet or untrusted zones using firewalls and access control lists. 3) Implement strict input validation: If custom integrations or scripts interact with QConvergeConsole, ensure they enforce strict validation and sanitization of file path inputs to prevent exploitation. 4) Monitor and log: Enable detailed logging of access to the QConvergeConsole and monitor for unusual file access patterns or repeated failed attempts that may indicate exploitation attempts. 5) Incident response readiness: Prepare to respond to potential denial-of-service incidents by having fallback procedures and backups for network management configurations. 6) Vendor engagement: Engage with Marvell support to obtain guidance, timelines for patches, and any recommended workarounds. 7) Access control hardening: Enforce strong authentication and authorization policies around network management tools to reduce risk from other vectors, even though this vulnerability does not require authentication.

Description

Marvell QConvergeConsole compressConfigFiles Directory Traversal Information Disclosure and Denial-of-Service Vulnerability. This vulnerability allows remote attackers to disclose sensitive information or to create a denial-of-service condition on affected installations of Marvell QConvergeConsole. Authentication is not required to exploit this vulnerability. The specific flaw exists within the implementation of the compressConfigFiles method. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to disclose sensitive information or to create a denial-of-service condition on the system. Was ZDI-CAN-24915.

Impact

For European organizations, the impact of this vulnerability can be substantial, especially for those relying on Marvell QConvergeConsole for network management and configuration tasks. Disclosure of sensitive information could lead to exposure of network configurations, credentials, or other critical operational data, which attackers could leverage for further intrusion or lateral movement within the network. The denial-of-service aspect could disrupt network management operations, potentially causing outages or degraded performance in critical infrastructure. This is particularly concerning for sectors such as telecommunications, manufacturing, and critical infrastructure operators where Marvell products are commonly deployed. The lack of authentication requirement means that attackers can exploit this vulnerability remotely without prior access, increasing the risk of widespread attacks. Given the critical nature of network management consoles, successful exploitation could undermine the integrity and availability of network services, impacting business continuity and regulatory compliance under frameworks like GDPR if personal or sensitive data is exposed.

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).
