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.

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

To mitigate CVE-2025-6799 effectively, European organizations should implement the following specific measures: 1) Immediate inventory and identification of all systems running Marvell QConvergeConsole version 5.5.0.78 to assess exposure. 3) Employ strict access control lists (ACLs) to limit which IP addresses or networks can reach the affected service, ideally restricting it to trusted internal management networks. 4) Monitor network traffic and system logs for unusual file access patterns or unauthorized requests targeting the getFileUploadBytes method or related endpoints. 5) Consider deploying Web Application Firewalls (WAFs) or Intrusion Prevention Systems (IPS) with custom rules to detect and block path traversal attempts. 6) Conduct security awareness and incident response drills focused on this vulnerability to ensure rapid detection and response. 7) Evaluate the feasibility of disabling or replacing the vulnerable component if patching is delayed, especially in high-risk environments. These targeted actions go beyond generic advice by focusing on immediate risk reduction and detection tailored to the vulnerability's characteristics.

Description

Marvell QConvergeConsole getFileUploadBytes Directory Traversal Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Marvell QConvergeConsole. Authentication is not required to exploit this vulnerability. The specific flaw exists within the implementation of the getFileUploadBytes 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 information in the context of SYSTEM. Was ZDI-CAN-24919.

Impact

For European organizations, the impact of CVE-2025-6799 can be significant, especially for those relying on Marvell QConvergeConsole for network device management or monitoring. The ability for unauthenticated attackers to remotely access sensitive system files can lead to exposure of confidential configuration data, credentials, or other critical information, potentially facilitating further attacks such as lateral movement, privilege escalation, or targeted espionage. Given that the vulnerability operates at SYSTEM privilege level, the confidentiality breach could be extensive. This risk is heightened in sectors with stringent data protection requirements, such as finance, healthcare, and critical infrastructure, where unauthorized disclosure could result in regulatory penalties, operational disruption, or reputational damage. Additionally, the vulnerability's network accessibility means attackers can exploit it remotely without needing to be on the internal network, increasing the attack surface. The absence of known exploits in the wild currently provides a window for proactive mitigation, but the high severity score and ease of exploitation necessitate urgent remediation to prevent potential future attacks.

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).
