Attack Vector: Network

Confidentiality: High
Integrity: High
Availability: None

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: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
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: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 26 Nov 2024
Detectable: evidence found.
nuclei template: Sharp Multifunction Printers - Cookie Exposure
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
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
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 2026-10-26.

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 consult Sharp Corporation’s official security advisories to identify affected models and apply vendor-provided patches or firmware updates as soon as they become available. 2. Until patches are deployed, restrict network access to Sharp MFP web interfaces by implementing network segmentation and firewall rules that limit access to trusted management networks only. 3. Disable or restrict access to the vulnerable web endpoints ('sessionlist.html' and 'sys_trayentryreboot.html') if possible through device configuration or web server controls. 4. Monitor network traffic and device logs for unusual access patterns or repeated requests to these endpoints, which may indicate exploitation attempts. 5. Enforce strong authentication and session management policies on MFPs, including session timeouts and use of secure cookies, to minimize session hijacking risks. 6. Conduct regular security assessments of networked printing devices and include them in vulnerability management programs. 7. Educate IT and security teams about the risks of embedded device web interfaces and the importance of timely patching and access controls. 8. Consider isolating MFPs on dedicated VLANs with strict ingress and egress filtering to reduce exposure.

Description

"sessionlist.html" and "sys_trayentryreboot.html" are accessible with no authentication. "sessionlist.html" provides logged-in users' session information including session cookies, and "sys_trayentryreboot.html" allows to reboot the device. 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, this vulnerability presents a significant risk to the confidentiality and integrity of sensitive information processed or stored on Sharp MFP devices. Attackers exploiting this flaw can hijack active sessions to gain unauthorized administrative access, potentially leading to data leakage, manipulation of print jobs, or configuration changes. The ability to reboot devices without authentication can disrupt business operations, causing denial of service and impacting productivity. Organizations in sectors such as government, finance, healthcare, and critical infrastructure that rely heavily on multifunction printers for document handling are particularly vulnerable. The exposure of session cookies can also facilitate lateral movement within internal networks if attackers gain footholds. Given the network-exploitable nature and lack of required privileges or user interaction, the threat surface is broad, especially in environments where MFPs are accessible from less secure network segments or exposed to the internet. This vulnerability could also undermine compliance with data protection regulations like GDPR if sensitive data is compromised.
