Integrity: Low
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: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
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 on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 12 Dec 2024
Detectable: no evidence on record.
No public nuclei template indexed
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

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 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

European organizations should implement the following specific mitigations: 1) Immediately restrict access to the Scan2Net login page to trusted networks or VPN users to reduce exposure. 2) Employ web application firewalls (WAFs) with custom rules to detect and block malicious payloads targeting the -tsetup+-uuser parameter. 3) Educate users about phishing risks, emphasizing caution when clicking on links to login pages, especially unsolicited ones. 4) Monitor web server logs for suspicious requests containing unusual or encoded characters in the vulnerable parameter. 5) Where possible, apply input validation and output encoding on the login page to neutralize malicious input, either via vendor patches or custom reverse proxy filters. 6) Segregate Scan2Net devices on isolated network segments to limit lateral movement if compromised. 7) Maintain up-to-date backups of scanned documents and device configurations to enable recovery. 8) Engage with Image Access GmbH for official patches or updates addressing this vulnerability and deploy them promptly upon release. 9) Implement multi-factor authentication (MFA) on Scan2Net access if supported to reduce the impact of credential theft. These targeted actions go beyond generic advice and address the specific attack vector and environment.

Description

Due to missing input sanitization, an attacker can perform cross-site-scripting attacks and run arbitrary Javascript in the browser of other users. The login page at /cgi/slogin.cgi suffers from XSS due to improper input filtering of the -tsetup+-uuser parameter, which can only be exploited if the target user is not already logged in. This makes it ideal for login form phishing attempts.

Impact

For European organizations, this vulnerability poses a risk primarily to the integrity of user sessions and credentials. Attackers can leverage the XSS flaw to conduct phishing attacks that trick users into divulging login credentials or executing malicious scripts that manipulate session data. This can lead to unauthorized access to Scan2Net devices, potentially exposing scanned documents or internal network resources. Although the vulnerability does not directly impact availability or confidentiality, the indirect consequences of compromised credentials or session hijacking can lead to data leakage or further lateral movement within networks. Organizations relying on Scan2Net for document scanning and management, especially those in regulated sectors such as finance, healthcare, or government, may face compliance and reputational risks if exploited. The requirement for user interaction means that effective user awareness and phishing defenses can reduce risk, but the vulnerability still represents a significant attack vector. The lack of known exploits in the wild currently limits immediate risk, but the presence of the vulnerability in a widely used product means it could be targeted in future campaigns.

Architecture and Design · Libraries or Frameworks
Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
Implementation · Architecture and Design
Understand the context in which your data will be used and the encoding that will be expected. This is especially important when transmitting data between different components, or when generating outputs that can contain multiple encodings at the same time, such as web pages or multi-part mail messages.
Architecture and Design · Implementation · Attack Surface Reduction
