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: 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: 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: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

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.

What to do

AI-suggested

Organizations should monitor Sharp Corporation advisories closely and apply firmware updates or patches as soon as they become available to address this vulnerability. Until patches are deployed, restrict physical and network access to MFP devices to trusted personnel only. Disable or tightly control coredump generation and storage on affected devices, ensuring that coredump files are encrypted or inaccessible to unauthorized users. Implement network segmentation to isolate MFPs from critical systems and sensitive data repositories. Regularly audit device logs and access records for signs of suspicious activity. Employ strong authentication mechanisms for device management interfaces and consider using network access control (NAC) to limit device connectivity. Educate IT staff about the risks of credential exposure in embedded devices and incorporate MFP security into broader endpoint protection strategies. Finally, consider replacing legacy or unsupported devices with models that follow modern security best practices for credential handling.

Description

User passwords are decrypted and stored on memory before any user logged in. Those decrypted passwords can be retrieved from the coredump file. As for the details of affected product names, model numbers, and versions, refer to the information provided by the respective vendors listed under [References].

Impact

For European organizations, the exposure of user passwords stored in recoverable plaintext format on Sharp MFPs poses a significant confidentiality risk. Multifunction printers often handle sensitive documents and are integrated into corporate networks, making them attractive targets for attackers seeking lateral movement or data exfiltration. If attackers gain access to coredump files or device memory, they could extract credentials and potentially access the device management interface or connected network resources. This could lead to unauthorized document access, interception of print jobs, or further compromise of internal systems. The impact is particularly critical in sectors such as government, finance, healthcare, and legal services, where document confidentiality is paramount. Additionally, the vulnerability could undermine trust in device security and compliance with data protection regulations like GDPR if sensitive information is leaked. However, the high attack complexity and lack of known exploits reduce immediate risk, though targeted attacks remain possible.

Summary

CVE-2024-32151 is a vulnerability identified in multiple Sharp Corporation multifunction printers (MFPs) where user passwords are handled insecurely. Specifically, user passwords are decrypted and stored in device memory before any user logs in. This decrypted password data can be retrieved from coredump files generated by the device, which are typically used for debugging but may be accessible to attackers with sufficient access. The vulnerability does not require any privileges or user interaction to exploit but has a high attack complexity, meaning it is not trivial to leverage without specific conditions or knowledge. The CVSS 3.1 base score is 5.9, reflecting a medium severity level, with a vector indicating network attack vector (AV:N), high attack complexity (AC:H), no privileges required (PR:N), no user interaction (UI:N), unchanged scope (S:U), high confidentiality impact (C:H), no integrity impact (I:N), and no availability impact (A:N). The main risk is confidentiality compromise through exposure of plaintext passwords, which could lead to unauthorized access to the MFP or connected systems if attackers retrieve and use these credentials. The affected product versions are detailed by Sharp Corporation in their advisories. No known exploits are currently reported in the wild. This vulnerability highlights the risk of improper credential handling in embedded systems and the importance of secure memory management and coredump protections.
