CVE-2025-58422 is a vulnerability identified in Ricoh Company, Ltd.'s RICOH Streamline NX product, specifically affecting versions 3.5.1 through 24R3. The vulnerability arises from the use of a less trusted source in handling HTTP requests within the product's management tool. An attacker capable of executing a man-in-the-middle (MitM) attack can intercept and modify the HTTP requests sent to the management tool. This manipulation can lead to tampering with the operation history logs maintained by the product. The operation history is critical for auditing and tracking administrative actions and system events. Altering these logs can undermine the integrity of audit trails, potentially concealing malicious activities or unauthorized changes. The vulnerability has a CVSS v3.0 base score of 3.1, classified as low severity. The vector string (AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:N) indicates that the attack is network-based, requires high attack complexity, no privileges, and user interaction is necessary. The impact is limited to integrity (I:L) with no confidentiality or availability impact. No known exploits are reported in the wild, and no patches or mitigation links are currently provided. The vulnerability emphasizes the risk of relying on untrusted or insufficiently secured communication channels within management tools, especially when sensitive audit data is involved.

For European organizations using RICOH Streamline NX, this vulnerability poses a risk primarily to the integrity of operational audit logs. Since the operation history can be tampered with, attackers could potentially cover their tracks after unauthorized access or malicious activities, complicating incident response and forensic investigations. This undermines trust in the system's audit capabilities, which are often critical for compliance with European regulations such as GDPR and NIS Directive that mandate reliable logging and monitoring. However, the low CVSS score and the requirement for a man-in-the-middle attack with user interaction reduce the likelihood of widespread exploitation. The impact is less severe on confidentiality and availability, but the integrity compromise could still facilitate insider threats or targeted attacks aiming to evade detection. Organizations relying heavily on RICOH Streamline NX for document workflow and management should be aware of this risk, especially in environments where sensitive or regulated data is processed.

To mitigate this vulnerability, European organizations should implement the following specific measures: 1) Ensure all communications with RICOH Streamline NX management tools are conducted over secure, encrypted channels such as HTTPS with strong TLS configurations to prevent MitM attacks. 2) Employ network segmentation and strict firewall rules to limit access to the management interface only to trusted administrative hosts and networks. 3) Use VPNs or other secure remote access solutions when remote management is necessary to reduce exposure to interception. 4) Monitor network traffic for unusual patterns that may indicate MitM attempts or unauthorized access. 5) Regularly review and verify operation history logs for inconsistencies or signs of tampering. 6) Engage with Ricoh support channels to obtain patches or updates as they become available and apply them promptly. 7) Educate users and administrators about the risk of interacting with suspicious links or prompts that could facilitate user interaction required for exploitation. These targeted actions go beyond generic advice by focusing on securing communication channels and monitoring integrity of audit logs specific to this vulnerability.
