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 2026-10-26.

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

1. Immediately review Sharp Corporation’s official advisories and apply any available firmware updates or patches addressing CVE-2024-29146. 2. Restrict network access to MFP management interfaces and disable unnecessary services to reduce exposure. 3. Limit physical access to devices to prevent unauthorized extraction of memory dumps or coredump files. 4. Implement network segmentation to isolate MFPs from sensitive network segments and critical assets. 5. Monitor logs and network traffic for unusual access patterns or attempts to retrieve memory dumps. 6. Enforce strong, unique passwords for device accounts and avoid credential reuse across systems. 7. Consider deploying endpoint detection and response (EDR) solutions capable of detecting anomalous activities related to MFPs. 8. Educate IT and security teams about the risks of credential exposure in embedded devices and incorporate MFPs into regular vulnerability management and security audits. 9. If possible, disable coredump generation or secure storage locations to prevent unauthorized access to memory snapshots. 10. Coordinate with Sharp support for guidance on secure configuration and incident response procedures related to this vulnerability.

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 decrypted user passwords from Sharp MFPs could lead to unauthorized access to the printers themselves and potentially lateral movement within the corporate network if the same credentials are reused or if the printer is integrated with network authentication systems. Confidentiality is the primary concern, as sensitive credentials could be harvested without alerting users or administrators. This could facilitate further attacks such as data exfiltration, interception of print jobs containing sensitive information, or use of the printer as a foothold for broader network compromise. The lack of integrity and availability impact means the device's operation is not directly disrupted, but the confidentiality breach alone can have serious consequences, especially in regulated industries like finance, healthcare, and government sectors prevalent in Europe. The medium severity rating suggests that while exploitation is not trivial due to high attack complexity, the potential damage from credential exposure warrants prompt attention. Organizations with large deployments of Sharp MFPs or those in critical infrastructure sectors should prioritize assessment and mitigation to reduce risk.

Summary

CVE-2024-29146 is a vulnerability identified in multiple Sharp Corporation multifunction printers (MFPs) whereby user passwords are decrypted and stored in the device's memory before any user logs in. This decrypted password data can be retrieved from coredump files generated by the device, which may be accessible to an attacker with network access or physical access to the device. The vulnerability does not require prior authentication or user interaction, increasing its risk profile. The CVSS 3.1 base score is 5.9, reflecting a 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 core issue is the insecure handling of sensitive credentials in memory, which can be exposed through memory dumps. While no known exploits are currently reported in the wild, the vulnerability could be leveraged by attackers to obtain user credentials, potentially facilitating unauthorized access to the printer or connected network resources. The affected product versions are detailed by Sharp Corporation in their advisories, and organizations should consult these for precise identification of impacted devices. This vulnerability highlights the importance of secure credential management in embedded devices such as MFPs, which are often overlooked in enterprise security strategies.
