Threat metrics

Exploit Maturity: POC

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

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, 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: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction: Passive: Successful exploitation of this vulnerability requires limited interaction by the targeted user with the vulnerable system and the attacker’s payload. These interactions would be considered involuntary and do not require that the user actively subvert protections built into the vulnerable system.
Vulnerable system confidentiality: None: There is no loss of confidentiality within the Vulnerable System.
Vulnerable system 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 to the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), CVSS vector, 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

To mitigate this vulnerability effectively, European organizations should: 1) Immediately verify if their Konica Minolta bizhub devices are running affected firmware versions (up to 20250202) and monitor vendor communications for official patches or firmware updates addressing CVE-2025-5885. 2) Implement network segmentation to isolate multifunction printers from critical network segments, limiting potential lateral movement if a device is compromised. 3) Employ web filtering and security awareness training to reduce the risk of users visiting malicious websites that could trigger CSRF attacks. 4) Disable or restrict remote web management interfaces on bizhub devices unless strictly necessary, and enforce strong access controls and authentication mechanisms for device management. 5) Monitor device logs and network traffic for unusual activity indicative of exploitation attempts. 6) If possible, apply compensating controls such as web application firewalls (WAFs) or intrusion prevention systems (IPS) to detect and block CSRF attack patterns targeting these devices. 7) Establish incident response procedures specific to multifunction device compromise scenarios to ensure rapid containment and remediation.

Description

A vulnerability has been found in Konica Minolta bizhub up to 20250202 and classified as problematic. This vulnerability affects unknown code. The manipulation leads to cross-site request forgery. The attack can be initiated remotely. The exploit has been disclosed to the public and may be used.

Impact

For European organizations, this vulnerability poses a moderate risk primarily to the integrity and availability of multifunction printer devices within corporate networks. Since bizhub devices are widely used in office environments across Europe, successful exploitation could disrupt business operations by altering device settings, interrupting printing services, or potentially exposing internal network segments if the device is used as a pivot point. Confidential data leakage is unlikely directly from this vulnerability, but operational disruption and unauthorized device control could have downstream effects on business continuity and information workflows. Organizations with large deployments of Konica Minolta bizhub devices, especially in sectors with high document processing needs such as finance, legal, and government, may face increased risk. The remote nature of the attack and lack of required authentication make it easier for attackers to attempt exploitation, especially if users are tricked into visiting malicious websites. However, the requirement for user interaction somewhat limits mass exploitation. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate it, especially as exploit code has been publicly disclosed.

Summary

CVE-2025-5885 is a Cross-Site Request Forgery (CSRF) vulnerability identified in Konica Minolta's bizhub product line, specifically affecting versions up to 20250202. CSRF vulnerabilities allow an attacker to trick an authenticated user into submitting a forged HTTP request to a web application in which they are currently authenticated, without their knowledge or consent. In this case, the vulnerability is remotely exploitable without requiring any authentication or privileges, and no user interaction beyond visiting a maliciously crafted webpage is necessary. The vulnerability does not affect confidentiality directly but can impact the integrity and availability of the affected system by enabling unauthorized commands or changes to be executed on the bizhub device. The CVSS v4.0 base score is 5.3, indicating a medium severity level. The attack vector is network-based (remote), with low attack complexity and no privileges or authentication required, but user interaction is needed (e.g., visiting a malicious site). The vulnerability does not involve confidentiality compromise but can cause limited integrity impact and low availability impact. No patches or mitigation links are currently provided, and no known exploits are reported in the wild yet. Given the nature of bizhub devices as multifunction printers often integrated into enterprise networks, exploitation could lead to unauthorized configuration changes, disruption of printing services, or potential pivoting points for further network attacks.
