Scope: Unchanged
Confidentiality: None
Integrity: Low
Availability: None

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Local: The vulnerable component is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either: the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or remotely (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., tricking a legitimate user into opening a malicious document).
Attack Complexity: High: A successful attack depends on conditions beyond the attacker's control. That is, a successful attack cannot be accomplished at will, but requires the attacker to invest in some measurable amount of effort in preparation or execution against the vulnerable component before a successful attack can be expected. For example, a successful attack may require an attacker to: gather knowledge about the environment in which the vulnerable target/component exists; prepare the target environment to improve exploit reliability; or inject themselves into the logical network path between the target and the resource requested by the victim in order to read and/or modify network communications (e.g., a man in the middle attack).
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
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: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 13 Jun 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
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 2026-10-25.

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

1. Network Segmentation: Restrict network access to the RICOH Streamline NX V3 PC Client upgrade servers and ensure that upgrade traffic is confined within trusted network segments to reduce the risk of MitM attacks. 2. Use of VPN or Encrypted Channels: Where possible, enforce the use of secure VPN tunnels or encrypted communication channels (e.g., TLS with certificate pinning) for upgrade requests to prevent interception and tampering. 3. Monitor Network Traffic: Implement network monitoring and intrusion detection systems to detect unusual traffic patterns or attempts at MitM attacks targeting upgrade processes. 4. Vendor Communication: Engage with Ricoh to obtain official patches or updates addressing this vulnerability as soon as they become available. 5. Application Whitelisting: Employ application control mechanisms to restrict execution of unauthorized DLLs or code on endpoints running the affected client. 6. Privilege Management: Limit user privileges on systems running the client to minimize the impact of potential code execution. 7. Regular Auditing: Conduct regular audits of client versions in use and upgrade to versions beyond 3.7.0 once patches are released. 8. Network Infrastructure Hardening: Harden network devices to prevent ARP spoofing or other MitM enabling techniques within local networks.

Description

RICOH Streamline NX V3 PC Client versions 3.5.0 to 3.7.0 contains an issue with use of less trusted source, which may allow an attacker who can conduct a man-in-the-middle attack to eavesdrop upgrade requests and execute a malicious DLL with custom code.

Impact

For European organizations using RICOH Streamline NX V3 PC Client versions 3.5.0 to 3.7.0, this vulnerability poses a risk primarily to the integrity of their systems. An attacker capable of conducting a MitM attack could inject malicious DLLs during the upgrade process, potentially leading to unauthorized code execution. While the vulnerability does not directly compromise confidentiality or availability, the execution of arbitrary code could be leveraged for further lateral movement, privilege escalation, or persistence within the affected environment. Organizations with sensitive printing workflows, document management, or confidential data processed through this client could face indirect risks if attackers manipulate or intercept upgrade processes. However, the requirement for local network access and high attack complexity limits the threat to environments where attackers can position themselves within the same network segment or have control over network infrastructure. Given that no exploits are currently known in the wild and the vulnerability does not require user interaction, the immediate risk is low but should not be ignored, especially in high-security environments or where Ricoh products are widely deployed.
