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: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to 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

Detectable: no evidence on record.
No public nuclei template indexed

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 26 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.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, 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.

2) Implement network segmentation to isolate systems running RICOH Streamline NX V3 PC Client from critical infrastructure and sensitive data repositories, limiting lateral movement in case of compromise. 3) Employ application whitelisting and endpoint detection and response (EDR) solutions to monitor and block unauthorized code execution attempts originating from the affected client. 4) Conduct thorough audits of file system permissions and restrict write access to directories used by the application to minimize the impact of path traversal exploitation. 5) Enhance network perimeter defenses with intrusion detection/prevention systems (IDS/IPS) configured to detect anomalous file access patterns or exploitation attempts related to path traversal. 6) Educate IT and security teams about the vulnerability specifics to ensure rapid incident response readiness. 7) Temporarily disable or restrict remote access to the RICOH Streamline NX V3 PC Client where feasible until patches are applied. These targeted measures go beyond generic advice by focusing on containment, detection, and minimizing attack surface specific to this vulnerability’s exploitation vector.

Description

Path traversal vulnerability exists in RICOH Streamline NX V3 PC Client versions 3.5.0 to 3.242.0. If this vulnerability is exploited, arbitrary code may be executed on the PC where the product is running by tampering with specific files used on the product.

Impact

For European organizations, the impact of CVE-2025-46783 could be substantial. Given that RICOH Streamline NX V3 PC Client is widely deployed in corporate and governmental environments for document and print management, exploitation could lead to unauthorized access to sensitive documents, intellectual property theft, and disruption of critical business operations. The ability to execute arbitrary code remotely without authentication means attackers could deploy malware, ransomware, or establish persistent footholds within networks. This could result in operational downtime, financial losses, reputational damage, and regulatory non-compliance, especially under stringent data protection laws like GDPR. Organizations in sectors such as finance, healthcare, government, and manufacturing, which rely heavily on secure document workflows, are particularly at risk. Additionally, the vulnerability could be leveraged as an initial entry point for broader cyber espionage or sabotage campaigns targeting European enterprises and public institutions.
