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: None: There is no loss of confidentiality within the impacted component.
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: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the impacted component are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 13 Jun 2025
Detectable: no evidence on record.
No public nuclei template indexed

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 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.

AI-suggested

Immediate mitigation should focus on restricting network access to the RICOH Streamline NX V3 PC Client to trusted internal networks only, using network segmentation and firewall rules to block unauthorized external traffic.
Monitor network traffic for unusual or malformed requests targeting the client application to detect potential exploitation attempts.
Implement application-level input validation and sanitization for file path parameters if possible through configuration or vendor updates.
Engage with Ricoh support channels to obtain and apply any forthcoming patches or updates addressing this vulnerability as soon as they become available.
As a temporary workaround, consider running the client with least privilege user accounts to limit the impact of file overwrites.
Regularly back up critical configuration and system files to enable quick recovery in case of file corruption or overwriting.
Conduct internal audits to identify all instances of the affected software across the organization to ensure comprehensive coverage of mitigation efforts.
Educate IT staff about this vulnerability to increase awareness and readiness to respond to potential incidents.

Description

External control of file name or path issue exists in RICOH Streamline NX V3 PC Client versions 3.5.0 to 3.242.0. If an attacker sends a specially crafted request, arbitrary files in the file system can be overwritten with log data.

Impact

For European organizations using RICOH Streamline NX V3 PC Client within the affected version range, this vulnerability poses a moderate risk. The ability to overwrite arbitrary files can disrupt document management workflows, potentially corrupting configuration files, logs, or other critical data. This could lead to denial of service conditions or data integrity issues, impacting business continuity. Organizations in sectors relying heavily on document processing and printing infrastructure, such as legal, financial, healthcare, and government institutions, may experience operational disruptions. Additionally, if critical system files are overwritten, it could require system restoration or reinstallation, increasing downtime and operational costs. While confidentiality is not directly impacted, the integrity and availability of systems are at risk. The lack of authentication requirement increases the attack surface, allowing remote attackers to exploit the vulnerability without prior access. Given the widespread use of Ricoh products in Europe, particularly in office environments, the threat could affect a broad range of organizations if exploited.
